Koch Chemie Alkali Wheel Cleaner Reviews

The price is a bit high but it's a very good wheel and tire cleaner and it's super concentrated. At 5:1 it is so strong and probably good for neglected wheels and tires. I've been using it 10:1 for weekly washes on my BMW M and AMG wheels and it does a great job. I noticed that the brake disks don't have a rusty look after using this as well as if it has some sort of rust inhibitor or something. It doesn't seem to affect the protection at this rate (10:1). Definitely way better than brake buster for my needs
