Question about automatic car wash

[HAMBO]

The spray from a touchless car wash is typically on the paint for like 30 seconds (at least the one near me, which I use rarely). Not sure how much stripping it can do in that short a period?

My issue with touchless washes is the poor drying, which I find always leaves water spots.

Do soaps and other chemicals from automatic
car wash strip off sealant and waxes that were
applied by hand?

•Whether they were applied by hand or by
machine...Waxes/Sealants will eventually
be degraded: by both environmental and
man-made contaminates; from car-washing
sessions (done at home, and/or at automatic
car wash facilities); whenever they experience
any “touching”...~Mike Phillips.

-This “touching” includes the vehicle being driven
in salted-conditions, which, IMO, is more degrading
to Waxes/Sealants than are most automatic car
wash’s chemicals.

I am planning to detail my daily with one coat
of Klasse sealant and one coat of Collinite 845.

I was wondering whether I should even bother
to detail my daily if I'm going to put it through
car wash through winter (maybe 10+ automatic
car washes until March).

If sealant and wax can somehow survive these
chemicals, I might as well go ahead and detail
my daily driver.

•Definitely detail your daily driver (DD) for
the upcoming Winter!

-Even if it takes 10 or more trips through the
automatics...something is better than nothing.

-And, as it often happens: There will be at least
one day during the Winter months when the
weather will be nice enough to re-Wax/re-Seal
vehicles.

Well, I did ask the manager before, but he
had no clue. I even called Esso office (gas
station near my house where the automatic
car wash is located), but I couldn't get an
answer. Both times, I straight up asked
whether the soaps are close to detergents in
terms of ph. But I believe those soaps are
pretty harsh...

Yes, there is some sort of "coating" sprayed
at the end of car wash tunnel

•By Law:
-This commercial business must have the SDS
data sheets for each and every chemical that’s
used at that facility—including the gas station’s.

•Something to consider:
-Removing contaminates from a vehicle during
a car-washing session usually takes agitation
with some type of tool (sponge, mitt, MF-towel)

-There is very little, to no agitation involved during
(brushless) Automatics’ car-washing sessions.
Therefore, and in order to remove as much contam-
ination as possible: their chemicals’ harshness levels
may be adjusted accordingly.

There are 3 levels of car washes. I believe middle
and top ones get the undercarriage wash, which
is the primary reason for taking the daily driver
to car wash during winter.

Getting the road salt/brine/etc. off the vehicle’s
top-side panels is also a very good reason, IMO.

I'm always interested in this kind of thing. Perfect chance for an experiment. Record the day you apply the Collinite, keep track of the number of washes, tell us if the car seems protected (beads water, etc.) in the Spring.

Ah. Will do. Please check back in March!

An even better experiment would be to have one panel not subjected to washing after Collinite application. Then in March wash that panel n see how it beads. But this does not seem possible since it is going through a car wash.

I used Klasse SG and Collinite 845 on my cars for a number of years and only saw a little degradation from the harsh soaps used in our touchless car washes. Over the warmer months when I'm hand washing, those products would last around six months. In the winter when they are bombarded by salt and road grime along with the touchless car washes they would last around 5 months.

As long as I applied the products in late September/early October I could get to March, though they would be ready for a refresh at that point.

I should have mentioned earlier, last year I used Meguiars Ultimate Fast Finish as my winter protection, and thought it held up quite well.

[Bobby B.]

The Klasse Sealant and Collinite #845 are pretty durable products. I don't use the automatic car washes on my car or their chemicals. I doubt they would strip off the Klasse and Collinite, but it probably will degrade them a little. I've never seen good results from automatic car washes. I would rather use the DIY pressure washer and bring a wash mitt and bottle of car soap with you.

They usually have signs up that say "No Bucket Washing" in the bays, but if you go at night they don't seem to care since nobody is there working.

[Bill D]

Definitely bring more than one mitt if you have to resort to the local car wash.

I, somewhat often, drive through the very close-by touch-less wash by my house. I'll come home and immediately then wash the car myself. Sometimes with a traditional bucket wash or other times, an ONR RW.

My car has Powerlock and Beadmaker (on one car) and just Megs HCW on the other car.
Neither car gets anywhere near losing its protection after the touch-less wash.


In the winter, granted I'm in Texas but it's currently below 40 today, I'll do the touch-less wash, then come home and do an ONR wash in my garage. It makes a RW so much better and easier whether I use MF towels or the BRS.
