Koch-Chemie Alkaline Wheel Cleaner 5L - Water Dilutable Wheel Cleaner

Recommended dilution ranges from 1:4 (1 part product, 4 parts water = 20%) to 1:20 (about 5%). This product is alkaline, meaning it has a high pH. It's gentler on surfaces like aluminum compared to acid-based wheel cleaners. If there's any damage to the wheel's paint, this cleaner won't accelerate corrosion as much as an acid-based cleaner would. It's also highly effective at removing dirt from tire sidewalls!

pH 13.4
