I have an '06 coupe with factory polished aluminum wheels. I've been cleaning them for years with various brands of wheel cleaner spray. I spray it on, brush it a bit with a big soft brush, and then hose it off. That simple process has seemed to work well.

Recently, I've seen some pitting/corrosion in a few "corners" where the spokes meet the wheel. Nothing too noticeable, but I'd like to clean it up if it's safe to do that. I presume that my factory wheels are clear-coated. (Anybody know for sure?) I've been thinking about getting some aluminum polish, cleaning up these corners, by polishing them out with a rag, then maybe "painting" some clear nail polish over the area so not to invite additional corrosion on the bare, just-cleaned aluminum.

That a good idea? Maybe better to just leave it be?

Any advice or comments would be appreciated. Thanks
