Oddly enough, I stumbled upon DI last night while searching the E90 detailing forum. Until then, I had always used Autogeek for detailing supplies. Anyway, I had never heard of waterless washes before. I think I am going to buy some. Do you have any experience with either of the products you mentioned? Do they leave a film or harm the paint in any way? Are they safe for cleaning wheels? Thanks for the info.
