How to wash and maintain a ceramic coated car
You have had a ceramic coating applied to your car.
The water beads amazingly, the paint feels slick, and the car has become significantly easier to keep clean.
But what now?
How do you actually wash a ceramic coated car correctly?
Do you need a special shampoo? Are you allowed to use an alkaline pre-wash? Does the coating need a booster? And what do you do if it suddenly no longer beads water like it used to?
A ceramic coating still requires maintenance.
But if you do it right, it is actually relatively simple.
In this guide, we walk you through the entire process.
If you are not yet quite sure what a ceramic coating is, you can start with our complete guide to ceramic coating.
Does a ceramic coated car still need to be washed?
Yes.
Ceramic coating does not mean the car is self-cleaning.
That is one of the biggest misconceptions about coatings.
A good coating makes the surface more hydrophobic and can make it harder for dirt to bond to the paint.
This typically means that the car becomes easier to wash.
But the car is still exposed to:
-
Traffic film
-
Insects
-
Bird droppings
-
Road salt
-
Brake dust
-
Rail dust/fallout
-
Limescale and minerals
-
Oily dirt
-
Pollen
Dust
If these things are allowed to build up on the surface, they can eventually mask some of the coating's properties.
Therefore, regular, correct washing is an important part of the maintenance.
How to wash a ceramic coated car
The basic washing method is actually the same as the one we recommend for other well-maintained cars:
Pre-wash → rinsing → hand wash → rinsing → drying.
The difference is that a well-functioning coating often makes the process easier.
Dirt releases more easily, and when you rinse the car, you will typically experience the characteristic hydrophobic effect.
Let's go through the process.
1. Start with a pre-wash
In our opinion, a good maintenance wash starts with a pre-wash.
The goal is to remove as much dirt as possible without physical contact with the paint.
This also applies to a coated car.
Even though the coating makes the surface easier to clean, we still don't want to drag unnecessary sand and dirt around with the wash mitt.
Therefore, apply a suitable pre-wash and let it work according to the manufacturer's instructions.
Then rinse the car thoroughly.
If you want to learn more about choosing a pre-wash, dry/wet car, alkaline pre-wash, and snow foam, you can read our complete guide to car pre-washing.
Can you use an alkaline pre-wash on a ceramic coating?
Yes – if the specific coating and pre-wash are compatible and the product is used correctly.
It is a misconception that a coated car must never come into contact with alkaline chemistry.
A quality ceramic coating is, among other things, interesting precisely because of its chemical resistance.
For a regular maintenance wash, however, it is not necessary to use the strongest chemicals every single time.
If the car is only lightly soiled, a milder pre-wash may be sufficient.
If, on the other hand, the car is covered in heavy winter film, salt, and greasy road grime, more cleaning power may be required.
The principle is:
Use the chemistry that the job requires – not automatically the strongest chemistry every time.
And always follow the manufacturer's recommendations for both the coating and the cleaning agent.
2. Rinse the car thoroughly
Once the pre-wash has had time to work, the car must be rinsed thoroughly.
This is where the coating's properties often clearly show.
On a clean and well-functioning coating, the water will typically either:
bead heavily
or
sheet off the surface quickly.
A good pressure washer with a decent water flow makes the job significantly easier.
If you are interested in the difference between pressure, water flow, and different machines, you can read our complete guide to pressure washers for car washing.
3. Hand wash the car
Even a ceramic coated car usually needs a contact wash to get completely clean.
After the pre-wash, there may still be a thin traffic film on the surface.
This is removed with:
-
A good car shampoo
-
A clean microfiber wash mitt or wash pad
-
Plenty of wash water
-
A gentle washing method
Work from top to bottom.
Save the car's dirtiest lower areas for last.
And do not apply unnecessary pressure.
Let the shampoo and wash mitt do the work.
Which shampoo should you use for ceramic coating?
For a regular maintenance wash, a good coating-safe car shampoo is an obvious choice.
Many prefer a pure shampoo without wax or other products that leave a new layer on top of the coating.
The advantage is that after washing, you see the coating's own properties.
There are also shampoos developed specifically for coated cars that can add hydrophobic properties during the wash.
Both solutions can have their place.
The most important thing is to choose a product based on what you want to achieve.
A pure shampoo
Good if you want effective cleaning and want to let the coating handle the protection and hydrophobicity.
A coating shampoo
Can be interesting if you also want to maintain or boost the hydrophobic effect during the wash.
However, we would not automatically conclude that a shampoo is good for coating just because it says "ceramic" on the bottle.
Cleaning ability and compatibility are more important than the name.
Can you use a stronger shampoo on a ceramic coating?
Yes, in situations where it is necessary and the coating is compatible with the product.
If a coating becomes covered in traffic film and other pollution over time, a regular mild maintenance shampoo may struggle to get the surface completely clean.
Here, a more intensive cleaning wash can be relevant.
This does not mean that we recommend strong chemicals every week.
But:
A coating that is never cleaned properly can eventually look as if it has lost its properties.
The problem might actually just be on top of the coating.
4. Rinse the shampoo off thoroughly
When the hand wash is finished, rinse the car thoroughly.
Make sure, in particular, to rinse around:
-
Mirrors
-
Emblems
-
Trim
-
Door handles
-
Panel gaps
-
License plates
Shampoo and water can hide here and run out later.
At this point, you also get a good indication of the coating's hydrophobic properties.
But remember:
A lack of water beads does not automatically mean the coating is gone.
We will come back to that.
5. Dry the car correctly
Even if the car is ceramic coated, we do not recommend just letting regular tap water dry on the paint.
Tap water contains minerals.
When the water evaporates, the minerals can be left behind.
The result can be:
Limescale spots / water spots.
And yes – they can also occur on top of a ceramic coating.
Therefore, use a large, clean, high-absorbency microfiber drying towel.
You don't need to press or scrub hard.
Let the towel absorb the water.
Limescale-free water is fantastic for coated cars
If you want to take the maintenance a step further, deionized/limescale-free water is extremely interesting.
By using water with a very low mineral content for the final rinse, you reduce the amount of minerals that can be left behind when the water evaporates.
This means:
Less risk of limescale spots and less need for physical wiping.
And less physical contact with the paint is always interesting when the goal is gentle car care.
We have made an entire guide on the subject:
Limescale spots on the car – how to remove and avoid them.
Does a ceramic coating need a booster?
Not necessarily.
A good ceramic coating does not need a spray coating after every single wash just to function.
But a coating topper, ceramic detailer, or other compatible maintenance protection can be useful.
It can, for example:
-
Increase gloss
-
Increase slickness
-
Provide extra hydrophobicity
-
Make drying easier
-
Act as a temporary top layer
But here is an important detail:
When you apply another protection product on top of the coating, it is largely the properties of the top product that you see immediately after.
If you test water beading the day after, you are therefore not necessarily testing the coating alone.
Should you use wax on top of a ceramic coating?
That would usually not be our first choice.
If you have invested in a ceramic coating, it makes more sense to use maintenance products that are developed to work with the coating.
A traditional wax on top of the coating can change the properties of the surface.
If you want to boost hydrophobicity or gloss, we would therefore typically choose a coating-compatible topper or detailer rather than a traditional wax.
How often should a ceramic coated car be washed?
There is no one correct interval.
It depends on:
-
How much the car is driven
-
Where it is parked
-
The season
-
The weather
-
How dirty it gets
-
How perfect you want to keep it
For many enthusiasts, every week or every other week will be a natural interval.
Others can easily go longer.
The most important thing is not a specific number of days.
The most important thing is that the car is not allowed to constantly build up thick layers of traffic film and pollution.
In winter, more frequent washing may be particularly relevant due to salt and heavy road film.
My ceramic coating no longer beads – is it ruined?
This is one of the questions we encounter most often.
You wash the car.
Rinse it.
But the perfect water beads are gone.
And the first thought is:
"My coating is dead."
Not necessarily.
A ceramic coating can eventually become covered in pollution.
For example:
-
Traffic film
-
Limescale
-
Minerals
-
Rail dust/fallout
-
Oily pollution
-
Residue from other car care products
These things lie on top of the coating.
Thus, it is not necessarily the coating's surface that the water is hitting anymore.
This can make the hydrophobicity appear significantly worse.
How to try to revive a coating
If the coating is no longer performing as before, we would not automatically apply another layer of product on top.
We would first try to find the cause.
Step 1 – thorough wash
Give the car a proper pre-wash and contact wash.
Step 2 – assess the hydrophobicity
Rinse the car.
Are the properties back?
Perfect.
If not, we move on.
Step 3 – remove mineral deposits
Limescale can settle on top of the coating and affect its properties.
Use a coating-safe water spot remover as needed.
Read our guide to limescale spots.
Step 4 – chemical decontamination
Rail dust and other stubborn pollution can also build up.
Here, a suitable iron remover or other chemical decontamination may be relevant.
Step 5 – test the coating again
Rinse the car thoroughly.
You might be surprised at how much hydrophobicity can return when the surface is actually clean again.
Should you use clay on a ceramic coating?
Here you have to be more careful.
Clay is a mechanical decontamination.
It involves physical contact and friction with the surface.
On a coated car, we would therefore generally try chemical decontamination first.
If mechanical decontamination becomes necessary, it must be done as gently as possible and with the understanding that the process can affect the surface.
Always start with the least aggressive solution.
Can you polish a ceramic coating?
If you machine polish the paint, you should count on affecting or removing the coating in the area you are polishing.
Polishing should therefore not be used as regular "maintenance" of a coating.
If the paint requires actual correction, the process will typically be:
Polishing → proper preparation → new coating on the area.
What do you do about limescale spots on the coating?
Take them as early as possible.
Fresh mineral deposits are typically easier to handle than old water spots.
Start with:
A thorough wash.
If that is not enough, the next step can be a dedicated coating-safe limescale remover/water spot remover.
That is yet another reason why we recommend correct drying or limescale-free water after car washing.
What about bird droppings and insects?
Remove them as soon as possible.
A ceramic coating is not an excuse to let a bird dropping bake onto the hood in the summer sun.
Bird droppings, insects, and other organic residues can be aggressive towards the surface.
Therefore, remove them gently but quickly.
If you have to remove a dried-on bird dropping, do not scrub it dry across the paint.
Soak it first and remove it carefully with suitable chemistry and clean microfiber equipment.
Can you take a ceramic coated car to an automated car wash?
Technically, the car can of course be washed in an automated car wash.
But if your goal is to keep the paint as nice as possible, we do not recommend car washes with brushes.
This is not because the brushes magically "ruin the coating".
The problem is the physical contact with the paint and the risk of wash marks.
A ceramic coating does not replace a good washing method.
If you have invested time and money in preparation and coating, it makes sense in our opinion to also wash the car gently afterward.
Nordic Pro Coatings – how to look after them
If you have applied Nordic Pro Coatings Pro 60 or GX yourself, the same basic principles apply.
Good maintenance is not about applying more and more product on top of the coating.
It is primarily about:
Keeping the coating's surface clean.
For the regular wash:
-
Good pre-wash
-
Gentle hand wash
Thorough rinsing
Thorough rinsing
Safe drying
When the car requires it, you can supplement with chemical decontamination.
This is especially important if the hydrophobicity begins to drop.
Pro 60 and GX are quality coatings with high chemical resistance, but that does not change the fact that dirt and minerals can still settle on top of the coating.
Keep the surface clean, and you give the coating the best conditions to show its properties.
If you are interested in the coating itself, the difference between Pro 60 and GX, or how you apply ceramic coating yourself, you can read our major guide to ceramic coating.
7 mistakes you should avoid with a ceramic-coated car
1. You think the car no longer needs washing
Coating makes maintenance easier – it does not replace it.
2. You skip the pre-wash
There is no reason to drag more dirt around on the paintwork than necessary.
3. You use the strongest chemicals every single week
Adjust the chemicals according to the car's condition.
4. You let tap water dry on the car
This can cause limescale spots – even on the coating.
5. You go straight for clay or a polishing machine
Start with chemical cleaning and the least aggressive method.
6. You declare the coating dead because the water doesn't bead
Clean and decontaminate the surface first.
7. You expect the coating to replace proper car care
It does not.
A good coating and a good washing method work together.
A simple maintenance plan
You don't need to make coating maintenance complicated.
For normal washing
Pre-wash → hand wash → rinse → dry.
When hydrophobicity decreases
Thorough cleaning → assess the coating → decontaminate as needed.
For limescale spots
Wash → coating-safe limescale remover as needed.
For industrial fallout and embedded contamination
Chemical decontamination as needed.
When the paintwork requires polishing
Be aware that polishing affects the coating, and the area may subsequently require a new coating.
It really doesn't have to be more complicated.
FAQ – maintenance of ceramic coating
How do you wash a ceramic-coated car?
Start with a pre-wash and a thorough rinse. Then hand-wash the car with a coating-compatible shampoo and a clean wash mitt. Rinse thoroughly and dry the car safely.
How often should a coated car be washed?
It depends on usage and conditions. Many enthusiasts wash it every week or every other week, but the most important thing is to avoid the long-term buildup of traffic film and contamination.
Do you need to use a special shampoo for ceramic coating?
Not necessarily a product with the word "ceramic" on the bottle. For regular maintenance, a good coating-safe shampoo is an obvious choice.
Is it okay to use alkaline pre-wash on ceramic coating?
A quality coating can be compatible with alkaline chemicals, but always follow the manufacturer's instructions. Use only the cleaning strength that the car actually needs.
Does a ceramic coating need a booster?
Not necessarily. A compatible topper can increase gloss, smoothness, and hydrophobicity, but the coating should not be dependent on a booster after every wash to function.
Why does my coating no longer bead?
The surface may be covered in traffic film, limescale, minerals, industrial fallout, or other impurities. Clean and decontaminate the coating before concluding that it has worn off.
Can you remove limescale from ceramic coating?
Yes. Use a suitable water spot remover/limescale remover that is compatible with the coating, and follow the product's instructions.
Can you polish a coated car?
Yes, but machine polishing will affect or remove the coating in the polished area. The area may therefore subsequently require a new coating.
Can you use clay on coating?
It may be possible, but mechanical decontamination creates physical contact with the surface. We therefore recommend starting with chemical decontamination and only using clay when it is actually necessary.
Can you use wax on top of a coating?
This is usually not necessary. If you want extra hydrophobicity or gloss, a coating-compatible topper will often be a more obvious choice.
Conclusion – keep the coating clean so it does its job
Maintenance of ceramic coating does not need to be complicated.
In fact, the most important piece of advice is incredibly simple:
Keep the surface clean.
Pre-wash the car.
Hand-wash it gently.
Dry it properly.
And when the coating eventually gets covered in traffic film, limescale, or other contamination, clean it properly instead of automatically concluding that the coating is gone.
A ceramic coating is designed to make car care easier – not to remove the need for car care.
If you have a coating like Nordic Pro Coatings Pro 60 or GX, you have already laid the foundation.
Now it is about giving the coating the right conditions to provide its hydrophobicity, chemical resistance, and ease of maintenance for as long as possible.
At Carfreak.dk, you will find everything for maintenance – from pre-wash, shampoo, and microfiber to limescale removers, pressure washers, and limescale-free water systems.
