How to Clean a Ceramic Coated Car
Ceramic coating makes routine maintenance easier, but it does not make your vehicle maintenance-free. Proper washing, drying and occasional decontamination are what keep the coating looking good and performing the way it should.
Ceramic coating aftercare is not complicated.
Avoid abrasive automatic washes.
Brush and cloth-strip washes can introduce marring and are not the maintenance method I recommend for coated paint.
Touch-free is acceptable.
It is not my first choice for every wash, but I understand that Wisconsin in February is not always the time for a driveway hand wash.
Hydrophobics can become clogged.
Road film, salt, minerals and contamination can sit on top of a healthy coating and make the water behavior look weak.
Drying matters.
Ceramic coating does not prevent water spots. Leaving water to evaporate can leave mineral deposits behind.
Complete ceramic coating aftercare
Give the coating time before its first full wash.
My general rule is simple: avoid a normal chemical wash for the first seven days.
The coating can encounter water before then. If your freshly coated vehicle gets caught in rain, there is no reason to panic. The bigger concern during the initial cure period is unnecessary washing, aggressive chemicals or letting contamination sit on the surface.
My preferred method: a two-bucket hand wash.
The goal is not to make washing complicated. The goal is to remove dirt while minimizing the amount of contamination you drag across the paint.
One for your wash solution and one for rinsing contamination from the mitt.
Place them in the buckets to help keep heavier contamination away from your wash media.
Use a quality coating-safe shampoo without unnecessary wax or heavy gloss additives.
Use clean microfiber wash media instead of household sponges or dirty brushes.
A large clean microfiber drying towel makes drying much easier and safer.
Optional, but useful as a pre-soak before the contact wash.
Rinse or pre-foam the vehicle.
If the vehicle is heavily soiled, rinse loose dirt and debris away first. A pressure washer is useful but not mandatory.
A foam cannon can also be used to loosen surface grime before you make contact with the paint.
Prepare the buckets.
Fill one bucket with clean rinse water. Fill the second with water and the recommended amount of automotive shampoo.
Wash from the top down.
Load the mitt with soap and wash a small section of the vehicle at a time.
Roof and upper glass first, then hood and upper doors. Save lower doors, rocker areas and the dirtiest sections for last.
Rinse the mitt often.
After a couple of panels, rinse the mitt in the clean-water bucket before putting it back into your wash solution.
Rinse thoroughly.
Remove the remaining soap from the paint, glass, trim, badges and other crevices.
Dry the vehicle.
Use a clean microfiber drying towel and allow the towel to absorb water instead of aggressively rubbing the paint.
A blower is excellent for mirrors, emblems, trim, wheels, grilles and other areas that continue dripping after a wash.
Can you take a ceramic coated vehicle through a car wash?
Brush and cloth-strip washes
The main concern is not that the machine instantly dissolves the ceramic coating.
The concern is repeated physical contact from wash material that has touched many vehicles before yours. That can introduce marring and scratches into the finish.
I also would not use the communal brush supplied at a self-service wash bay on your paint.
Touch-free automatic washes
A touch-free wash is not necessarily how I would maintain the vehicle every single time, but it is a realistic option.
I live in Wisconsin too. I understand that you probably are not standing in your driveway doing a relaxed hand wash when it is freezing outside.
Touch-free is especially useful when the alternative is allowing weeks of salt and road film to remain on the vehicle.
I try to keep the maintenance rules simple.
Weak beading does not automatically mean your coating is gone.
One of the most common maintenance mistakes is assuming that weaker hydrophobics equals coating failure.
Road film, surfactants, winter brine, iron contamination and mineral deposits can accumulate on top of a coating and change how water behaves.
In Wisconsin this is especially common after winter. Lower doors and rocker areas can look noticeably less hydrophobic simply because the surface is contaminated.
You do not need to use a topper after every wash.
Maintenance sprays can increase slickness, gloss and visible water beading. They are useful, but they are not something I consider mandatory after every wash.
Use them when needed or when you want to refresh the surface. If the coating seems badly clogged, clean the contamination first instead of repeatedly covering the problem with another layer of maintenance product.
Start with the least aggressive method that does the job.
Strong degreasers
They are rarely necessary for routine washing and can temporarily flatten the hydrophobic behavior of the surface.
Aggressive acids or alkaline cleaners
Specialized chemistry has a place in decontamination, but routine maintenance usually does not require highly aggressive products.
Polishing compounds
Polishing is abrasive. It can reduce or remove the coating and should not be treated as a normal cleaning step.
Clay bars
Do not routinely clay a ceramic coated vehicle. Clay is abrasive and can create marring or alter the coated surface.
How I clean ceramic coated glass
You usually do not need an aggressive glass cleaner.
For normal fingerprints, bug residue and light contamination, a high-quality microfiber towel and a simple mixture of distilled water and isopropyl alcohol can work extremely well.
- Lightly mist a 50/50 distilled-water and isopropyl-alcohol mixture onto the glass.
- Use less product than you think you need. Saturating the window usually creates more streaking, not less.
- Fold a clean microfiber towel into quarters.
- Clean the glass with one face of the towel.
- Flip to a clean dry face and perform the final wipe.
Coated wheels usually need less aggression, not more.
If the coating is doing its job, brake dust should release much more easily.
That is why I prefer starting with normal wash soap and a dedicated microfiber towel rather than immediately reaching for strong wheel acids or aggressive brushes.
- Finish washing the painted surfaces first.
- Use a separate microfiber towel or wheel-specific wash media.
- Wipe the wheel faces and spokes with your normal wash solution.
- Rinse thoroughly.
- Do not return dirty wheel towels to paint duty.
Bugs, bird droppings, salt, sap, tar and hard water
My approach is almost always the same: start mild and only become more aggressive when the contamination actually requires it.
Do not let them bake for weeks.
Bug residue is acidic. A day or two is normally not a reason to panic, but repeatedly allowing bug guts to bake onto the front bumper, mirrors and grille is unnecessary.
Start with your normal wash method. For spot cleaning, the distilled-water and isopropyl-alcohol mixture used elsewhere in this guide can be useful.
Remove them when reasonably possible.
I prefer a wash because bird droppings can contain grit and you do not want to unnecessarily smear that contamination across the paint.
If you cannot wash immediately, soften the contamination and remove it gently with clean microfiber rather than dry-rubbing it.
Wisconsin winter changes the maintenance routine.
Do not let months of winter road film accumulate simply because it is cold outside.
Touch-free washing is a realistic winter option. For stubborn salt film, a dedicated salt-removal product such as Star brite Salt Off can also be useful when used according to its directions.
Start with a normal wash before escalating.
Sometimes what looks severe before washing is mostly surface mineral residue that comes off during a normal contact wash.
If rings remain afterward, a dedicated mineral-removal product or mild acidic treatment may be required.
Read the full water-spot guide →Fresh sap is much easier than hardened sap.
A mild alcohol mixture can help soften fresh residue. Hardened sap becomes substantially more difficult and is one of the situations where I would rather see the vehicle professionally than tell someone to scrape at their paint.
Use chemistry before abrasion.
A coating often makes tar easier to remove, but stubborn contamination can still require dedicated tar-removal chemistry.
I do not recommend routine claying of a coated vehicle. If mechanical decontamination becomes necessary, understand that it can mar the surface and may lead to polishing afterward.
This is one I would not experiment with.
Paint thinners, strippers and strong solvents can create a much larger problem if they are used incorrectly.
If road paint is bonded to painted or plastic surfaces, my recommendation is professional removal rather than experimenting with aggressive solvents after watching a quick video online.
Usually a once-or-twice-a-year job.
Iron contamination can build up even on coated paint. A coating-safe iron remover is useful periodically, especially after a Wisconsin winter.
Use it on a cool surface, out of direct sunlight, and never let the chemical dry on the vehicle.
Exterior: product on the surface. Interior: product on the towel.
Spray the surface when appropriate.
On exterior paint, glass and similar surfaces, applying the cleaning product to the contaminated area gives the chemistry a chance to begin breaking down the residue before wiping.
Work in small areas, follow the product instructions and do not allow the cleaner to dry on the surface.
Spray the towel first.
For dashboards, screens, switches, plastics, leather and other interior materials, I prefer spraying the microfiber towel rather than the vehicle.
That gives you better control and reduces the chance of cleaner running into seams, electronics, buttons or speaker openings.
Clean towels matter more than expensive towels.
A premium microfiber towel filled with debris is still a dirty towel being dragged across your paint.
You do not need a cabinet full of detailing chemicals.
These are examples of products I have used for the jobs described below. They are not requirements for maintaining a ceramic coating.
Autofiber Mr. Everything
A versatile microfiber for glass, maintenance sprays, spot cleaning and general-purpose exterior work.
Autofiber Dreadnought
A highly absorbent drying towel. Let the towel absorb the water instead of unnecessarily scrubbing the paint.
3D Pink Car Soap
A straightforward automotive shampoo that works well in a wash bucket, foam gun or foam cannon.
Gtechniq C2 Liquid Crystal
Useful when you want to refresh slickness, gloss and water behavior. It does not need to be applied after every wash.
Gtechniq W6
Useful periodically for metallic fallout on paint and wheels. For most owners, this is an occasional decontamination step, not an every-wash chemical.
Koch-Chemie ASC
A useful ready-to-use interior cleaner. Spray the microfiber towel first rather than saturating interior controls and surfaces.
Star brite Salt Off
Originally designed around salt exposure in marine environments, but useful for stubborn winter salt film when used according to the manufacturer directions.
Distilled Water + Isopropyl Alcohol
A 50/50 mixture is one of the simple tools I commonly use for glass and light exterior spot-cleaning situations.
What is the point of an annual ceramic coating inspection?
The annual visit is not just somebody looking at the vehicle for five minutes and sending you home.
It gives me a chance to properly clean the exterior, evaluate how the coating is behaving, address contamination and apply a maintenance topper.
Spring is especially useful in Wisconsin because winter salt, road film and contamination tend to load the lower portions of a vehicle.
Annual inspection is required for my applicable 5-year coating program. If you have a coating installed elsewhere, contact me before assuming I can take over another installer's maintenance schedule. My maintenance program is increasingly focused on coatings I installed myself.
More about annual inspections and referral credits →Ceramic coating maintenance: do this, not that.
- Wash the vehicle roughly every two weeks to once a month when practical.
- Use a two-bucket hand wash when possible.
- Use clean microfiber wash media and drying towels.
- Dry the vehicle instead of intentionally letting water evaporate.
- Remove bugs, bird droppings and sap in a reasonable amount of time.
- Use iron-removal and mineral-removal chemistry when actual contamination calls for it.
- Use a ceramic maintenance spray as needed rather than automatically after every wash.
- Complete required professional inspections for your coating program.
- Use brush-style automatic car washes as your normal routine.
- Scrub the vehicle with the communal self-wash-bay brush.
- Assume ceramic coating makes the vehicle scratch-proof.
- Assume ceramic coating prevents water spots.
- Routinely clay-bar the coated paint.
- Use harsh degreasers simply because the vehicle is dirty.
- Polish a coated vehicle without understanding that polishing can reduce or remove the coating.
- Assume weak beading automatically means the ceramic coating failed.
Clean it before you declare it dead.
A contaminated coating can behave completely differently from a clean coating. Before assuming you need another installation, diagnose what is actually sitting on the surface.
