These brake dust are very stubborn. Even wax can't remove them.. spent sometime today using my Soft99 on my 17" type 158 rim and not happy with the result. Afraid to use rim cleaner spray, which works wonder with instant effect to melt the brake dust and tar stuck on the rim. Are they corrosive?
What do u meant by brake dust repellent? So brake dust repel and would stay on the rim? or just make it easier to clean the rim?
