Cleaning the alloy wheels

it seems like my wheels are pitted, is there any way I can get my wheels cleaned again? Maybe have it done at a shop or something? Thanks

best thing that I could tell you is to soak it with armoral rim cleaner. it is the best stuff that i have ever used. it pulled up stuff that I never thought would come off. It is in a grey spray bottle.

how long should I soak it in? Can I just leave the wheel on the car?

let is sit for about 3-5 minutes. if you want to get the inside of the rim then I suggest that you take the rim off but if you just want the outer suface thn just keep it on the car.
