Well, I just got my new flamed valve covers from Billet Industries, and in the course of installing them, they got dirty. So I decided to wash the engine, then polish them back to their former glory. However, as I was using someone else's garage, I used Greased Lightning cleaner. Oops.

Quickly realizing my mistake, i washed off the car, but the covers are 'burned' where the greased lighting hit them. So my question is, will polishing them restore them, or something more intensive be required? As I am polishing my rims as we speak, sandpaper/compounds aren't hard to come by.

This is what i get for thinking engine cleaners should CLEAN engines. *goes and hugs Simple Green bottle*

 

At the most you will need is some buffing wheels to buff them, I bet aluminum polish and some elbow grease could take the stains off

 

yeah some mother`s mag and aluminum polish should take the burns right out,so no worries

 

Big props to everyone for answering

And Jesus does trying to sand the last *******'s curb rash out of rims suck...but you knew that already, didn't you?
