Chalk it up to a learning experience...or just stupidity on my part...
I have one of those Thumlers Tumblers (the big Red one) which has a rubber liner inside. Love the tumbler...works great.
Lately I've been tumble cleaning pistol brass with SS pins, Dawn soap and Lemi Shine. Has been working great...so of course I decided to make it even better by adding a capful or two of Dillon Rapid Polish 290. After reading the directions...seemed simple enough. Away we go.
What I DIDN'T know was that it is petroleum based...hence it doesn't like rubber. dang. All of the brass was completely black as well as the steel pins. Washed the brass afterwards...didn't help. Yuk. Black ink-water everywhere. What a mess.
Tumbled a second time (after cleaning up all the black water) and brass is back to good again...in fact the best looking brass I've ever cleaned due to having been tumbled twice. Whew.
But anyone who has a tumbler with a rubber liner, beware of adding the Dillon polish to your recipe.
