<<Mag and wire wheel cleaners can contain phosphoric or other stronger acids. This can damage the clear coat powder coated materials. The gloss finish is etched. Bob>> List - i would not recommend anyone try using this product ("Eagle-1 Chrome and Wire Wheel Cleaner"). the bottle clearly says not to use it on polished aluminum or motorcycle wire wheels, and does not say a THING about powdercoated chrome wheels or magnesium. you would think that if it damaged powdercoated chrome wheels, it would say that, right? i guess not. i am in the process of filing a damage claim against Eagle-1 and hoping they will pay for refinishing. i am very upset.
