Touchless car washes require very very strong cleaners in order to break down dirt and debris. It's just science. There's not a whole lot of arguing it. It will slowly strip away at your coatings, wax and could damage clear coats over time. I'd avoid these.

 

Automated car washes have become much better over the years, BUT you need to go a to a high quality one. Do some research, find one that uses high quality cloth brushes and has employees 24/7 versus one of those ones you go through at a gas station that no one ever maintains or looks at. There's a lot recently, especially here in DFW that have popped up. They spend millions on them.

 

Best way to wash is 2 bucket method...but it's time consuming.

Drive-up spray wand washes are good/fine. But you'll still need to use the 2 bucket method. The brushes that most of them have are crap.

 

It comes down to how much you care. Some people are ****** about their cars and will only hand wash. But I don't have time for that and in my mind...it's a truck not a supercar. I go through a high quality automated wash.

If a touchless car wash is having those kinds of issues, they are using the wrong chemical profile. 

There are many effective products on the market that are very gentle on the surface, or clearcoat being cleaned, but very aggressive on the dirt being removed. As far as waxes getting stripped, again, the right chemicals will not affect waxes much. Besides, wax gets stripped bit by bit from rain/wind,snow, sun, washing, etc.

 

I never use carwashes with brushes, as they are problematic for a number of reasons.

I’ve never found a touchless that is worth the $10-$20 they charge here. All junk. I shake my head when I see people drive through the touchless and you still see the dirt haze left on the truck. What a waste of $$$.  I go to the heated bay in the winter and spray off and then hand dry. 
but like others have said nothing better then 2 bucket wash method. Gets truck completely clean.

I have a monthly pass for my black AT4 with 29,500 miles at a drive thru WITH brushes.  Brushless are worthless and don't clean anything.  I'm very happy with the protocol I utilize and truck looks great.  I run it through about twice a week.

 

I do the same thing with the car pictured as my Avatar.  IMHO, too much ado about nothing regarding brushed drive through washes.  As long as it's a well maintained, high quality drive through you're good to go.

I agree to an extent.......

 

I have been through dozens of touchless washes over the years.  Some nice and new, some old and ratty.  99.99% of them do exactly what you mention.

 

That said, the local touchless here will bring my truck with 1/4" of salt on it to shining like new.  I think it's in part because I keep her waxed and in part the quality of the water used.  I don't get the haze I do with most washes.  I mean, even the windshield is clean from side to side/top to bottom.  No haze where the wipers don't hit.

 

Moral of the story.. not all touchless washes are the same

I second that. Many years monthly pass. Many colors including black, never a problem. I use quick detail about once a month and that’s it.

Feel like everyones tolerance level for automatic wash scratches is different. But they all leave ‘em and in the sun you can see them. The lower down on the vehicle you go, the worse and deeper they get because that’s where the dirt is. Especially up here with the salt and sand they use. All of the stuff off the cars in front of you gets rubbed into your paint. Nobody is cleaning the brushes between cars. Even at the fully staffed conveyor belt wash we have in town.

Sadly I must agree.  Especially on black.  I do the touchless when I can't hand wash but I keep trying brushed systems in HOPES one day to find one that doesn't scratch.

 

On a tangent, just replaced my Portal-Cable DA (7424XP) with a Milwaukee 2738 buffer.  Having it cordless and non-DA should be able to de-swirl much faster now

I must be one of the ****** truck owners then, only hand wash in the spring/summer and gets the wand washes throughout the winter.  My summer cars will never see anything but 2 bucket wash method.  If you want to not have to spend hours cleaning it, invest either your time or money into a proper ppe or ceramic coating, then your paint will look great with minimal effort after the fact.

 

Just finished putting 2 coats go collinite on the Z06 to finish off the bottle, few months will ceramic coat it.  

 

Depends on what type of owner you are, everyone has their preference; to each their own I always say!

The car washes I go to have water constantly flowing through the brushes and over the vehicle. Even when there’s no vehicle. So they’re constantly rinsing. The brushes are cloth. I dare say better than a 2 bucket wash. Unless you have the garden hose in one hand while you wipe with the other at the same time running water and soap over it. Of course that pretty much impossible for a human to do. That’s what happens at the car washes I use. Water, soap, cloth brushes all at the same time. I dare say car washes are better for that reason, not worse.

Very happy with my ceramic. All it ever needs is a quick run through a touchless wash, and all the dirt falls right off and it looks perfect.

A year ago I could not have seen myself agree with this. Then I was given a bottle of a hybrid ceramic wax, a cousin, yes? Well it is a fraction of the work to clean it. So I tired it on the Wife's white Terrain. What a awful color to keep clean and what an awful paint. Ceramic wax and the dirt slides off like water off a ducks back. BUT. I'm not paying thousands for a ceramic finish application. So this will have to do. Anyway MG386 thanks for the set up. Good post!

    • My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.
    • Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken. 
    • Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.
    • I have 2 choices. 
    • Do you have access to BP fuels? Some stations have Silver 91 E-0 priced the same as their 93 E-10.  There is a local Marathon with 90 alky free for $6 a gallon but I go down the road to BP for $5-ish. They also have a 100 E-0 but that stuff is $10 a pop.
