How to polish your car – a complete guide to car polishing

Do you want more shine in the paintwork? Is your car full of wash swirls? Or do you want to prep the paint perfectly before applying a ceramic coating?

Then polishing your car is the next step.

A proper polish can make a huge difference to tired paint. Minor wash swirls, oxidation, holograms, and other superficial defects can be reduced or removed, while giving the paint significantly more shine and depth.

But there is one important thing to understand:

Polishing is not just cleaning the paintwork.

With corrective polishing, you are working on the paint surface itself, removing a very small amount of material to level out defects in the clear coat.

That is why it must be done correctly.

In this guide, we walk you through the entire process from car washing and decontamination to choosing a polisher, polish, and polishing pad – and, of course, what to do with the paint afterward.

---

What is car polishing?

When a car is polished, you work the paint surface using a polishing agent and typically a polishing machine.

The goal can be to:

• Remove or reduce wash swirls

• Reduce holograms

• Remove oxidation

• Reduce minor paint defects

• Restore gloss

• Create more depth in the paint

• Prepare the paint for coating or other paint protection

On most modern cars, the paint structure generally consists of:

Primer → color coat → clear coat.

It is usually the clear coat that we work with during polishing.

---

How can polishing remove scratches?

It might sound strange.

How can something that is already scratched become smooth again?

Imagine a small scratch in the clear coat.

Scratches make the surface uneven and affect how light is reflected.

In corrective polishing, an abrasive polishing agent works together with the polishing pad on the paint surface.

Instead of "filling in" the scratches, you remove a microscopic amount of the surface around the defect.

When the difference between the surface and the scratch area is reduced, the scratches become less visible – or, in some cases, can be removed completely.

Therefore, in practice, polishing is:

Controlled paint correction.

---

Can all scratches be polished away?

No.

And that is an important point.

Not all scratches should or can be polished away.

Superficial wash swirls and minor defects in the clear coat can often be corrected very nicely.

However, if a scratch is very deep or goes all the way through the clear coat and color coat, polishing cannot magically restore missing paint.

A very simple rule of thumb is:

If the scratches are only superficial in the clear coat, there are often good possibilities for improvement.

If the scratches are very deep, they may require a different form of paint repair.

We will later provide a complete guide on scratches in the paint and which scratches can be polished away.

---

What are wash swirls?

The classic small, circular marks that you especially see in sunlight are often called:

Swirls or wash scratches.

They typically arise from many small mechanical influences on the paint.

This can, for example, be:

• Incorrect hand washing

• Dirty wash mitts

• Low-quality microfiber cloths

• Automatic car wash with brushes

• Drying a dirty car

• Lack of pre-washing

• Incorrect drying techniques

On a black car, wash swirls can be extremely visible in direct sunlight.

On a light-colored car, those exact same defects can be far harder to see.

But they may still be there.

---

Should the car be washed before polishing?

Yes. Absolutely.

You should never begin polishing a dirty car.

Before polishing, the paint must be as clean as possible.

Among other things, we want to remove:

• General road grime

• Traffic film

• Tar

• Iron fallout

• Insects

• Other stuck-on contaminants

If there is contamination on the paint, you risk dragging it around during polishing.

Therefore, a good polish actually starts long before the polishing machine is turned on.

---

Step 1 – wash the car thoroughly

Start with a proper car wash.

We recommend:

Pre-wash → thorough rinsing → hand wash → rinsing.

The goal is to get the car as clean as possible without creating new wash swirls.

If you want the entire process explained from start to finish, you can read our complete guide to proper car washing.

You can also read our guide to proper pre-washing.

---

Step 2 – remove iron fallout

Even if the paint looks clean after washing, there may still be iron-based contamination on the surface.

This is often called:

Iron fallout or iron contamination.

Especially on light-colored cars, it can appear as small orange or brownish dots.

Before major polishing, it makes good sense to have this type of contamination removed.

Use a suitable iron remover according to the manufacturer's instructions.

Read our complete guide to iron fallout on the car.

---

Step 3 – remove tar

Tar and asphalt spots should also not be dragged around under the polishing pad.

Tar is often seen as small black dots, especially on:

• The lower part of the doors

• Fenders

• Side skirts

• The area behind the wheels

Use a dedicated tar remover.

Read our guide to removing tar spots.

---

Step 4 – mechanical decontamination as needed

After chemical decontamination, there may still be bonded contamination on the paint.

Here, clay can be used.

Clay is available as, for example:

• Clay bar

• Clay mitt

• Clay towel

• Clay pad

The purpose is to remove bonded contamination that regular washing and chemical decontamination haven't removed.

However, clay must be used correctly and with sufficient lubrication.

Clay can in fact leave minor marks on the paint itself.

Therefore, clay makes particular sense before a planned polishing, where any minor marks can subsequently be corrected.

Do not use clay just for the sake of it.

Use it when the paint needs it.

---

How do you know if the paint needs clay?

After washing and chemical decontamination, you can carefully feel the paint.

Clean paint should feel very smooth.

If the surface still feels:

rough, bumpy, or like sandpaper, there may be bonded contamination.

Then mechanical decontamination may be relevant.

---

Step 5 – dry the car thoroughly

Before polishing, the car must be dry.

Be especially aware of water hiding:

• Around mirrors

• In emblems

• By trim

• Around handles

• By panel edges

There is almost nothing more annoying than starting to polish and having a stream of water running down the panel.

---

Step 6 – inspect the paintwork

Now comes an important part.

Look at the paint.

Not just in regular ceiling light.

Feel free to use a good inspection light or a strong point light source.

Here you can identify:

• Wash swirls

• Holograms

• Deeper scratches

• Oxidation

• Etchings

• Other paint defects

Only when you know what you are trying to correct can you choose the right combination of machine, pad, and polishing agent.

---

Which polishing machine should you choose?

There are several types of polishing machines.

The most common are:

DA polisher

DA stands for Dual Action.

The machine combines rotation with an oscillating movement.

This makes the DA machine very popular among both enthusiasts and professionals.

For the beginner, a modern DA polisher will often be a really good place to start.

Forced rotation / gear-driven

Here, the movement is forced through the machine's gear mechanism.

This provides a different workflow and high corrective capacity.

Rotary polisher

Here, the pad rotates around one fixed axis.

A rotary machine can be extremely effective, but also requires more experience and control.

For many hobby users, we would therefore typically recommend starting with:

A good DA polisher.

---

Can a beginner polish their own car?

Yes.

Modern DA polishers and polishing systems have made machine polishing far more accessible.

But:

That does not mean you should just turn on the machine and attack the entire car.

Start in a controlled manner.

Get to know the product.

And most importantly:

Do a test spot first.

---

Test spot – the most important step in polishing

Before you polish the whole car, choose a smaller area.

For example, around:

40 x 40 cm.

Here you test the combination of:

• Polishing machine

• Polishing pad

• Polishing agent

• Speed

• Working time

• Technique

Once the area is polished, wipe off the product residue and inspect the result.

Ask yourself:

Have I achieved the correction and finish I want?

If yes:

Fantastic.

Then you have found a combination that works on that specific paint.

If no:

Then you adjust.

---

Do not start with the coarsest combination

A classic beginner mistake is:

“There are scratches. I need to use the coarsest compound and the hardest pad.”

Not necessarily.

A good principle in polishing is:

Start with the least aggressive combination that can solve the task satisfactorily.

If a milder combination gives 90% of the desired result, there is not necessarily any reason to go extremely aggressive.

Remember:

When you correct the paint, you are working with a limited amount of clear coat.

Clear coat does not grow back.

---

What is polishing agent?

Polishing agent contains, among other things, abrasives that help correct the paint surface.

But polishing agents come in different grades.

One often speaks of:

Compound

Higher corrective effect.

Used for more severe defects.

Medium polish

A compromise between heavy correction and high finish.

Finishing polish

Focus on maximum finish, gloss, and removal of minor defects.

But modern polishing agents are making these boundaries more fluid.

Some products can deliver both good correction and a really nice finish in one step.

---

What is one-step polishing?

One-step means that you try to achieve both:

correction + nice finish

in one polishing process.

It is extremely popular.

And for good reason.

On many cars, the goal is not necessarily to chase every single microscopic defect.

The goal can be:

To make the car significantly nicer in a reasonable amount of time.

Here, a one-step polish can be perfect.

It can reduce a large portion of the wash swirls while giving significantly more shine.

---

What is two-step polishing?

On more neglected paint, you can work in two steps.

Step 1 – cutting

Here you focus on correction with a coarser combination.

Step 2 – finishing

Then you use a finer combination to maximize the finish and remove any haze or traces from the first step.

It takes longer.

But on very scratched or demanding paint, the result can be significantly better.

---

Which polishing pad should you choose?

The polishing pad is at least as important as the polishing agent.

Pads come in different materials and hardnesses.

Typically, we see:

Wool

High corrective capacity in the right systems.

Microfiber

Can provide powerful correction and is often used together with DA polishers.

Foam

Available in many different hardnesses from cutting to ultrafine finishing.

Therefore, there is not one:

“best polishing pad”.

You choose a pad based on:

paint + defect + polishing agent + desired result.

---

Hard or soft polishing pad?

Roughly speaking:

Harder/aggressive pad → more correction

Softer/finer pad → more focus on finish

But the system must be evaluated as a whole.

A pad works together with:

• The machine

• The polishing agent

• The paint type

• Your technique

Therefore, the test spot is again your best friend.

---

How much polishing agent should you use?

More is not automatically better.

If the pad is drowning in product, the system does not necessarily work better.

Follow the recommendations for the specific polishing agent and the specific pad.

With a new/dry pad, it may require a little product to be correctly primed.

After that, typically much less product is used per section.

You should polish the car – not marinate it.

---

How to use a DA polisher

The precise method depends on the machine and the polishing system, but the basic principles are:

1. Distribute the product

Distribute the polishing agent over the work area so that you do not start the machine with all the product in one spot.

2. Hold the pad correctly against the paint

With a DA polisher, you generally want the pad to work stably against the surface.

3. Work in smaller sections

Do not try to polish an entire hood at once.

Work systematically.

4. Use controlled movements

Work in overlapping passes.

5. Keep an eye on temperature and product

You do not need to keep working the product forever.

6. Wipe off

Use a clean, soft microfiber cloth.

7. Inspect

See the result in good light.

And repeat as needed.

---

How hard should you press the polisher?

This depends on the machine, pad, and polishing system.

More pressure does not automatically mean more correction.

Too much pressure can affect the machine's movement, create unnecessary heat, and make the process less effective.

Use controlled pressure according to the recommendations for your system.

And let:

the machine + the pad + the abrasives

do the work.

---

How fast should the polisher be moved?

Not like a vacuum cleaner five minutes before guests arrive.

If you move the machine extremely quickly over the paint, the polishing system does not get proper time to work.

Use calm and controlled movements with overlapping passes.

It is all about:

control over speed.

---

Be careful with edges and body lines

Edges and sharp body lines require extra attention.

The paint structure and working conditions are not necessarily the same as on a large, flat surface.

Therefore, you should not treat a sharp edge the same way as the middle of a large hood.

Be conservative.

Especially if you do not know the car's history.

---

Do you know how much paint is left?

On an older or previously polished car, you do not necessarily know:

• Whether the car has been wet sanded previously

• How many times it has been polished

• Whether panels have been repainted

• How much clear coat has been removed previously

Professional detailers may therefore use a paint thickness gauge as part of the assessment.

A paint thickness gauge does not tell you everything, but it can provide valuable information.

Especially when working with heavy correction.

---

Should you tape off the car?

It can be a very good idea.

Masking tape can be used to protect, for example:

• Untreated plastic

• Rubber trim

• Sensitive edges

• Emblems

• Other areas you do not want polish on

It also makes the work more controlled.

---

How many polishing pads should you use for a car?

More than one.

A classic mistake is trying to polish the entire car with one pad.

During work, the pad collects:

• Polish

• Removed material

• Paint residue

• Contamination

This affects the pad's ability to work correctly.

Therefore, pads must be cleaned regularly and replaced during work.

For an entire car, it makes a lot of sense to have several identical pads ready.

---

Clean the polishing pad as you go

A clean pad works better.

Depending on the pad type, it can be cleaned as you go using, for example, a suitable pad brush, compressed air, or another method recommended for the system.

You do not want a pad that, after half the car, is completely saturated with polish and residue.

Clean pads = more uniform work.

---

How do you wipe off polish?

Use a clean and soft microfiber cloth.

Avoid applying heavy pressure to the paint.

Fold the cloth so you have several clean sides available, and change the cloth as needed.

It would be a real shame to spend hours correcting wash scratches only to create new ones during wipe-off.

---

Must the car be absolutely perfect?

That is up to you.

And it is actually an important part of polishing.

On a regular daily driver, it can be much more sensible to achieve:

a major visual improvement

rather than chasing:

100% defect-free paint.

Removing the last deep defects can require a disproportionate amount of paint correction.

Sometimes the right decision is simply:

That scratch is allowed to stay.

Paint preservation is more important than perfection.

---

Can you polish a new car?

Yes.

A new car does not necessarily mean perfect paint.

A factory-new car may already have:

• Transport marks

• Wash scratches

• Small defects

• Holograms from preparation

• Bonded contamination

If you want to ceramic coat a new car, a light polish can therefore still be relevant.

But:

Assess the paint first.

If it only requires a very light finishing, there is no reason to perform heavy correction.

---

Can you polish the car by hand?

Yes, but the possibilities are more limited.

On small areas, hand polishing can be fine.

But if the goal is real paint correction on an entire car, a polishing machine provides much more uniform and effective work.

For an entire car, we would therefore clearly prefer:

machine polishing.

---

Can you polish the car outside?

It is possible, but the conditions are far worse.

Ideally, we want to polish:

• In the shade

• On cool paint

• Without rain

• Without heavy wind

• Without dust

• With good working light

A garage or other covered workspace is therefore clearly preferred.

Direct sunlight and hot paint make the work unnecessarily difficult.

---

Does the paint need to be cleaned after polishing?

If you are subsequently going to apply a ceramic coating, proper preparation is extremely important.

Polishes can leave behind:

• Oils

• Residue

• Other ingredients

on the surface.

Therefore, a suitable panel wipe / paint prep is typically used before coating.

The purpose is to leave the surface:

clean and ready for the coating's bonding.

Always follow the coating manufacturer's preparation instructions.

---

What should be done after polishing?

After polishing, the paint looks great.

But it should also be protected.

You can, for example, choose:

• Wax

• Paint sealant

• Spray coating

• Ceramic coating

The choice depends on the desired durability, properties, and how much work you want to put into the process.

If you want long-lasting protection and easier maintenance, a ceramic coating is an interesting choice.

Read our complete guide to ceramic coating.

---

Ceramic coating does not make the car scratch-proof

It is important that we get this established.

A ceramic coating can, among other things, provide:

• Chemical resistance

• Hydrophobic properties

• Easier maintenance

• Gloss

• Protection of the surface against various environmental influences

But:

Ceramic coating does not make the paint scratch-proof.

And it does not replace physical protection against, for example, stone chips.

If you want physical protection against stone chips and other mechanical impacts, it is PPF – Paint Protection Film – you should look at.

---

How long does it take to polish a car?

It depends heavily on the level of ambition.

A faster one-step polish and a comprehensive multi-step paint correction are two completely different projects.

The time depends, among other things, on:

• The size of the car

• The condition of the paint

• Paint type

• Number of polishing steps

• Experience

• Number of defects

• How detailed the work is performed

If it is your first time polishing:

Set aside plenty of time.

Polishing does not get better from stress.

---

What do I need to polish the car?

A good beginner's kit will typically consist of:

• DA polisher

• Polish

• Appropriate polishing pads

• Several pads of the same type

• Microfiber cloths

• Inspection light

• Masking tape

• Panel wipe, if the car is subsequently to be protected/coated

And before you even get there:

• Car shampoo

• Pre-wash

• Fallout remover

• Tar remover

• Possibly clay

At Carfreak.dk, you will find equipment for the entire process from washing and decontamination to polishing and subsequent paint protection.

12 classic mistakes when polishing a car

1. You are polishing a dirty car

The paint must be cleaned and decontaminated first.

2. You start with the coarsest combination

Do a test spot and start as mild as possible.

3. You try to remove all scratches

Some scratches should be allowed to remain.

4. You use one pad for the entire car

Change and clean pads regularly.

5. You use way too much polish

More product is not automatically better.

6. You work on an area that is too large

Work in controlled sections.

7. You move the machine too fast

Give the system a chance to work.

8. You ignore edges

Be extra careful on sharp edges and body lines.

9. You work in direct sunlight

Cool paint and controlled conditions are much better.

10. You use dirty microfiber cloths

This can create new marks.

11. You forget to inspect the result

Good light is crucial.

12. You do not protect the paint afterwards

After all the work, it makes sense to protect the result.

FAQ – car polishing

How do you polish a car?

The car is first washed and decontaminated thoroughly. Then the paint is inspected, and a suitable combination of polisher, polishing pad, and polish is tested on a small area. When the right combination is found, the car is polished systematically, section by section.

Can you polish your car yourself?

Yes. A modern DA polisher is a good starting point for many enthusiasts and beginners. Start mild, do a test area, and work in a controlled manner.

Can polishing remove scratches?

Polishing can remove or reduce many superficial defects in the clear coat. Deep scratches through the paint layers cannot necessarily be polished away.

Which polisher is best for beginners?

A DA polisher is often a good choice due to its combined rotating and oscillating movement and general ease of use.

What is the difference between compound and polish?

Compound typically has a greater corrective effect, while finer polish focuses more on finish and gloss. Modern products can, however, combine several properties.

What does one-step polishing mean?

One-step means that you attempt to achieve both good correction and a nice finish in one polishing step.

What does two-step polishing mean?

Here, a more corrective step is performed first, followed by a finer finishing step.

Should the car be clayed before polishing?

Only if needed. If bonded contamination still remains on the paint after washing and chemical decontamination, clay can be relevant.

Should you use a coating after polishing?

It is not a requirement, but the paint should be protected after polishing. This can be done with wax, paint sealant, spray coating, or ceramic coating.

Does ceramic coating make the car scratch-proof?

No. Ceramic coating does not make the car scratch-proof and does not replace PPF as physical protection against, for example, stone chips.

How often can you polish a car?

There is no one correct interval. Corrective polishing removes a small amount of paint/clear coat, so the car should be polished as needed rather than on a fixed calendar basis.

Can you polish a brand new car?

Yes. New cars can also have minor paint defects and bonded contamination. Always assess the condition of the paint and use only the necessary degree of correction.

---

Conclusion – how to get the best result with polishing

Polishing can transform the look of a car.

But the best result does not come from buying:

the most powerful machine + the coarsest pad + the coarsest compound.

It comes from understanding the paint.

Start with a thorough wash and decontamination.

Examine the paint.

Do a test spot.

Start with the least aggressive combination that gives the desired result.

Work systematically.

Keep pads and microfiber clean.

And accept that not all scratches necessarily need to be removed.

The goal is not to remove as much clear coat as possible.

The goal is to create the best possible paintwork with as little unnecessary correction as possible.

When the polishing is done, protect the result with the paint protection that suits your needs.

If you want to build the entire process correctly, we recommend continuing with our guides:

Then you have the whole chain:

Wash → decontamination → polishing → protection.

And that is the foundation for paint that not only looks clean – but truly stands sharp.
