The Truth About Ceramic Coating Maintenance (From a Pro Detailer)
What I’ve learned over 30+ years as a professional detailer.

One of the most common questions I get from my clients after I’ve applied one of my professional-grade ceramic coatings to their paint is something like, “What do I do from now on to maintain this beautiful shine?!” or “Do I need to do anything special, or use special products on my freshly ceramic coated car?”
My experience of seeing literally thousands of vehicles of various ages and conditions confirms that hand washing is always the best way to clean your car, but I also see that in the real-world many people simply cannot hand wash their car. Maybe they live in an apartment complex that doesn’t allow car washing, or they have a physical restriction that prevents them from hand washing, or it’s simply too cold and uncomfortable during 30-degree weather to drag a hose out and wash a car without your fingers freezing off!
So my response to the initial question about how best to wash a car is this, “It’s always best to hand wash your car, but if you cannot hand wash it when it gets dirty the next best solution is to use a high-quality drive-through wash.”
Wait… a professional detailer recommending a drive-thru automatic wash? Yes, as long as you’re using them as infrequently as possible, and you’re using the highest quality wash in your area (here in Washington County, Oregon we have Cruiser’s Corner Carwash, and the Kaady Carwash chain that are both very high quality).
I’d much rather see you keep your car clean even if it means introducing the lightest swirl marks from an automatic wash than to leave all the nasty contaminants lying on your paint for months on end until you can hand wash it clean again.
What about touchless drive-thru washes? These won’t introduce swirl marks on your paint, but they also tend to not clean as well, and have the nasty habit of degrading your plastics much faster due to the extreme pH chemicals they must use to compensate for not touching your car. You’ll see your exterior trims and plastics fading much faster if you frequently use these touchless-washes.
Sure your new ceramic coating provides you with a measure of protection against those contaminants (like bird poop, tree sap blobs, bug splatters, and pollen deposits) but even the best ceramic coating will begin to degrade after months of contact with those very harsh items.
So it’s a trade… do you want very light swirls that are easily polished out by a professional, or do you want permanent stains that require repaint? Those are literally your 2 options when deciding whether to use a drive-thru wash. The smart choice is to keep your car clean.
Does a ceramic coating prevent swirls from an automatic carwash? Not as much as we’d all like. I’ve seen it many times over the years, a client loves their new car so much with their amazing ceramic coating on their brand new black paint, that when even the slightest layer of dust accumulates after a day or two they hit their local drive-thru wash to keep their paint spotless. They end up over-washing their car and cause significantly more wash-induced swirls than is normal for their aged car. Sure they kept their car clean as a whistle, but at what cost? A light dusting of your everyday pollen and dust is no cause to wash your car. You should only wash your car when it is truly dirty, usually only every few weeks under most circumstances.
On the other end of the spectrum, you should still wash your car in the rain, even if you know it’s going to get dirty again a few minutes afterwards by driving on the still-wet roads. Why? Back to the concept of keeping damage-causing environmental contaminants from sitting on your paint too long. “Exchange the old dirt or new dirt” has been my mantra for decades. Just like brushing your teeth regularly, you’d never say something like “I’m not going to brush my teeth today because I know they’re just going to get dirty again when I eat later today.”
When hand washing your ceramic coated car, what special chemicals/cleaners are required?
Any professionally applied high-quality ceramic coating can be washed by over-the-counter carwash soaps. Nothing you buy at the store or online is going to strip off the ceramic coating. However, you can help prolong your coating and help its hydrophobic properties by using a rinse less type product like Opti-Coat No Rinse because it leaves behind polymers that further help keep those ever-damaging contaminants from bonding to your paint. Cheap carwash soaps that have fillers and waxes will leave behind residues that build up and “clog” your coating, which diminishes its hydrophobic (water beading) properties.
To sum this up, these special steps aren’t additional work for ceramic coated cars, they’re actually the baseline preservation methods I recommend for any car, coated or not.
