I don't know for sure but I thought those touchless car washes used harsh chemicals to clean I wouldn't want that on my dinoc. I wash my car at home with a car brush and dry with those fake shammies. I too hate to drive in the rain just because it's so much work cleaning them.
I wash mine by hand because there are next to no car wash businesses locally. The main reason I wash it is because we have a lot of leaves and pollen and my house doesn't have a lot of sun == instant mildew\mold\black gunk all over the car in the spring and fall. It turns the car black until I wash it off. It rains a ton out here and my di-noc is wasted so I just make sure that the car continues to be driven above 55MPH after it rains to dry it out and keep the water from pooling\accumulating (which it loves to do in the tail gate area on a glide-away...).
most of the time I just wash my cars down by hand. Never also thought I would use those waterless car wash liquids, but did try it about 4 months ago and have to say I now use it all the time. Unless your car is real dirty, I use it. If real dirty I go to the car wash but dry car off soonest as best I can. Luckily we live in mostly dry weather. Before I go to the car wash I apply wheel cleaner just before entering the wash so most of the brake dust comes off.
I saw this one on a car show sometime ago http://www.wsj.com/video/inside-germany-fanciest-car-wash-/72D4FDEE-F748-45BB-8B1A-1B9D97F1F7FE.html more than impressive
1949 Dodge Coronet coupe. It has a full bench rear seat. It belonged to the Dodge dealer's daughter. Driven very little. In 1956 when I bought it from the dealership all of the paper work, books, and tags were still hanging from the various underdash things. I washed and waxed it so often the grey primer was beginning to show on the fender tops and edges. I hated the fluid drive yet it was smooth and rode nice. One advantage, I could start and stop in high gear without the clutch or without shifting. Better for driving with my arm around my girlfriend. I still have the girlfriend but not the car.
Does your wife know, Sir? After viewing this, you'd hate to be one of those poor dregs doing the interiors:
I've gone to a similar car wash close to one of my doctors. But it's 30 miles from home just to get there. Still a little closer than the one in Germany. If I went there, I'd need my car washed after I got home. That salt water is tough on metal.
I wash them at home with a power washer and microfiber towels. Is anyone here familiar with the detailing company Ammo NYC? They make their own detailing products including some unusual ones (which products are there made for removing brake dust but AMMO Plum? I haven't looked,) and they have detailing videos on Youtube.
