What do you use to clean aluminum alloy rims on your bike. As a reference my bike is a Kawasaki ZZR 600, Mine is chain driven and has a grease buildup on it? I was thinking of using kerosene on a rag to break through it but didn't want to damage the rims? A buddy mentioned Simple Green to use to cut the crud? I talked with someone else that said S-100 soap with a toilet brush would work? So what do you use? Also I have a chrome pipe and then a brushed aluminum for a muffler? What to use for that as well? Thanks Esox357.
