Default Automatic touchless car wash on Ceramic Coat

Anyone here take their car through touchless car washes in the winter? Now that I have a white WRX.. literally every time there is a bit of slush it looks nasty after and its beyond ONR yet too cold outside to wash with a foam canon or 2 bucket. Hows the coating holding up to the harsh soaps they use?

Oh yes, it's a must keeping the paint clean.
I even go to the self carwash first to spray the wheel wheels and under carriage before going though the automatic touchless carwash because it does not clean the underside of the car well enough.

Well - not sure how good touch-less is at cleaning - better off just using a pressure washer or self wash for $3 pressure rinse....

If it’s no problem on non-coated cars (I’ve used touchless for a decade on my old wrx), don’t know how it could be an issue on cars with ceramic.

I think he is more concerned about the coating being washed off by the acids.

My fault for not phrasing it correctly. I meant that ceramic is supposed to be better and more durable than a wax job so it should last. If it can't hold up to touchless soaps then what's the point of it? But I guess that's a different topic. fwiw, i think you'll be alright.

Two years in, and having only once used one of the "mandatory" top coat maintenance products, touchless washes haven't noticeably degraded the performance of the ceramic coating. If I'm honest, I run the Porsche through a touchless wash far more often than I wash it by hand. Water still beads up nicely.

As long as you're not paying for their BS "Tricolor polish" or rainX then it shouldn't have negative effects on your coating.

With that being said I've used the bottom tier wash on several coated vehicles when they're lightly to moderately dirty without issue.

You could give yourself a prerinse with some diluted APC in the parking lot on the heavily soiled areas.

I do the same as Cobrakai stated. Get the cheapest wash. Once you start getting all those other specials, it will take away from your coating's function.

I did it a few times and noticed water wasn't beading as good as it did. Ended up purchasing the soap to reset the coating and its back to as good as new. I keep a bottle of the quick detail spray for my cquartz coating in the car now and do a quick wipe down after any automatic touchless wash.

Please correct me if I'm wrong, but any ceramic coating that I've seen doesn't wash off, you have to buff it off with an abrasive.

It would have to be a pretty strong acidic or alkaline solution to wash it off.

This is exactly what I was looking for.. someone with a coated car that goes through these on occasion and has been coated for 2 years now. Thanks!
