I should preface this with the fact that I live in a very small town, in which there is only one car wash. At the car wash there are obligatory pressure washer bays, vacuum stations, etc. On the other side there is a small bay where they do detailing. I always take the necessary precautions of telling them to only hand wash, not use pressure washers, no simple-green, etc. Today I got my car back with the wierdest film on the wheels. I have the OEM Exige black wheels, so it obviously stands out easily, but I can only compare it to what sweat stains look like on clothing (white/gray, pooling, dripping) I immediately asked what they used, to which they showed me an unmarked, generic spray bottle with mystery fluid inside. I've tried scrubbing with a bristle brush with water and soap, and Turtle Wax wheel cleaner, but it just won't budge. It also looks like it even ate away at the caliper paint too . Anyone have any experience in this area? Recommendations? Advice? :shrug: I'll take pictures and post them up if it will help. It's a shame to have a beautifully detailed Exige with wheels that look like they've been neglected for months.
