What do you use to CLEAN audio equipment CASES?
I have searched this site and the internet for days, and cannot find an answer to this (simple?) question! Specifically, what products, chemicals or procedures do you use to clean and/or refurbish (usually BLACK) metal audio equipment cases (such as YAMAHA amps, etc.)? Is there a procedure to repair scratches in such cases? Any and all help will be greatly appreciated.
