my 13 old wheels need some help! theyre dingy and no longer can be cleaned by conventional means, is there any product that will get them to shine again? i dont care if its acidic or not, the coating is pretty much gone anyway. and for the glass, all the windows except my front windshield have some hardcore water spots on them, ive tried lots of glass cleaning products, and nothing works on them, would something like CLR do the trick? any help is appreciated, thanks
