Richy's thread about his White Trans Am clean up reminded me of something I heard mentioned at the auto auction some time back.
They run two lanes of cars and do everything at various stations along the way. Kind of like the tunnel car washes except they do whatever has been requested to a vehicle.
The thing that came to mind was a seller mentioning what a great job they did bringing back a white car he had for sale.
They told him they acid washed every white car that they did a full exterior detail on. The guy that runs the shop really believes in acid washing. He thinks it is something that almost transforms a white car. He said you would have to see it to believe how much crap just rolls off.
This is a true production line operation that does 300+ cars per week. They aren't hacks and the cars come out looking pretty good. I have no idea what they use for brands of product since it is either dispensed through a system of hoses or kept in generic bottles.
The only two things I have noticed that I would take exception to is wet carpets after extraction, but in fairness to them, it might have just been done minutes before. The other thing is the engine dressing. After they clean the engine compartment, they just spray a bunch of dressing, (from one of those overhead dispensing hoses), all over the entire engine compartment.
Back on topic.
How many of you have experience with acid washes?
I don't think it would be something for the hobby detailer at all, but it might have a place for the professional. Chances are, you would need a fixed location to make it work, but I really have no idea.
