ok before i start i dont use a coin op but this weekend i was in a hurry. i noticed that a couple of days before i did the IP,FP, P21 and there was no marring or spiderwebs then after i washed the car at a coin op i noticed some of the marring was back. well when i did the ip and fp i used the 50/50 mix and there were no swirls so should do you guys think im right........:confused:
 
How was your washing process different at the coin op than what you normally do? If all you used was their rinse then things should have been fine.



Compare your normal wash process with what you did at the coin op and I'm sure you'll discover the problem.
 
If you used the foaming brush, then yes, it will mar your paint. The presoak is also a no-no since it is a very strong soap.



When I have to use a coin op, I use a wash mitt and pour some of my own car wash soap on the pad to clean my car. Make sure you do that when the owner is not around or at least let the water run the whole time.
 
well before i washed them at home with 2 buckets and never had that problem, for some reason i thing the thought of pressure washing might induce some. before when i washed them at home they would never come back...
 
If you use the soaps from the car wash, you are just asking for problems, IMO. Pressure washing alone should not induce marring.
 
Along the same line of thinking as Scott, I don't think the pressure washer is inducing marring, but instead it may be revealing what is there. The soap and presoaking stuff is pretty harsh and can quickly start to remove some of the fillers, oils and such used in some polishes, glazes and carnauba based waxes. The result is the marring that was being covered up with the products is revealed.



That said I have used the coin ops/ touchless washes many times (especially during the winter). You can definitely tell that the soaps remove protection and drastically reduce the durability. However, this doesn't bother me as I "wax" often.
 
They use a watered down acid in their soaps. Esp in the touchless washes. They will hurt your finish bigtime. Aside from stripping any protection you had the will also speed up oxidation. Oxidation is when your paint is starved. If you don't use the right car soap that you buy yourself you can contibute, nevermind the stuff they use. I use the "Sottwax" method. I go at night when nobody's there and use my soap and mit aswell.

"Many people continue to wash their car with dish washing detergent (e.g., Dawn), which quickly degrades automotive plastic, rubber and paint. On the basis of overwhelming evidence, dishwashing detergent will destroy your clearcoat finish over time. Dishwashing detergents are formulated to remove grease and oils. Detergents easily strip wax protection from your paint and moisture from rubber seals and trim. The same damage occurs if you put your car through most coin-op car washes. In order to clean without brushes, coin-op car wash systems must use strong detergents.

The ideal wash product for the clearcoat finish has the following characteristics:



pH-balanced (should be slightly alkaline to counteract the acidic conditions found on most roadways).



Good lubrication to protect your clearcoat from scratching and swirl marks.



No residue (free rinsing, no streaking).



Glossing agents to restore shine and make drying easier."
 
I did a rinse only at 10-12+" away and experienced...

What is a safe spray nozzle distance to prevent the above?
