Side panel exhaust stain

[fatchance]

Anybody ever try the old household solution that seems to work on just about everything? You know, distilled vinegar, baking soda and hydrogen peroxide.

I use acetone, take the stains right off, but don't rub too long it will take the shine away. Then rinse with soap and water. Use a white rag.
