The question comes up from time to time on how to clean tarnished brass. While rebuilding my Tyco 10 wheelers, I need to clean up the brass domes on these things, so I thought I would show you how I have been cleaning the tarnish off of those brass domes.
The United States Navy used to polish the brass fittings, railings and such on their ships with an effective polish, so I got some some and put a thin layer of it on the brass dome
After letting it sit for half an hour, I rubbed the stuff off with a napkin.
I know, napkins are for drawing plans on, so forgive me for using one to polish up brass.
This super secret brass cleaner? Its common household Ketchup (catsup).
It seams the vinegar and salt in the Ketchup will remove tarnish from brass. And the best part, for me, is that its cheep. In fact, it is even free at most fast food restaurants. I like free.
