Hi there.. as i know all rim cleaner products are pure acids so there is always the danger of corrosion especially if the paint is not very good quality or many layers.. Once i had mine to be washed, they used some kind of these liquids on my wheels and from then first time i saw all my brake discs to get dark brown and rusted
.. From then i decided not to use any kind of these liquids again... I prefer to use high pressure water on the calipers which cleans them well...
Any other opinions are welcome... come on guys!!
Cheers to all
