Stain/old brake dust

Can anyone give any advice about products or home cleaning solutions to help get these caked on stains/brake dust off the rim

 

Baking soda / White vineger mix usually does the trick for almost anything I need done around the house. Also safe chemicals to safe for everything. Not sure for automotive so maybe be weary of over spray on components or paint and or wash and clean after.

 

P&S Brake Buster is a fantastic tire & wheel cleaner.

 

Looks like the finish is damaged in the picture? Is the paint starting to bubble?

 

I'd second P&S Brake Buster. If that doesn't work, you can also try a dedicated iron remover. If your wheels are clear-coated, you could also try an acid-based wheel cleaner as a last resort. Acid-based cleaners will stain bare metal, so if you aren't sure if they are clear-coated, I would avoid going that route.
