I bought some Bilberry Wheel Safe Cleaner from i4detailing to clean my Volks.
Read the instructions and proceeded to use it 1:1 neat, because I thought they were very dirty.
Proceeded to spray all four wheels, let it dwell and then resprayed and then agitated with a brush.
When I was doing the brushwork, I noticed to my horror that where the cleaner had pooled in the dish, it had eaten the lacquer.
I then finished cleaning the car in a somber mood, didn't even wax her.
Dried the car and then put some Rimwax on the wheels so it had at least some sort of protection from further damage.
Here are some pics after the wheels have been cleaned and have wax on them...
Lesson for the future...ALWAYS DILUTE BILBERRY!!!
