Hi, I am looking for a home-made solution for cleaning my steel
shot (not stainless).The shot has served me well for a long time
now it is getting rusty and greasy (why greasy?)
Here’s what works for me. I use about 7 # of assorted shapes of shot
in the smallest vibratory tumbler Gemstone Equip. makes.
When it gets grungy I dump the shot in a colander & rinse it off
under hot water. While the shot is out of the tumbler, I rinse it out
as well & dry it. Then I put the shot back in the tumbler add some
Draino (the dry kind) or lye (sodium hydroxide) & add water until
about 1/2 the shot is under water. Place the lid on the tumbler & run
it for and hour or so. Dump the shot in the colander again & rinse in
hot water. Clean out the tumbler. If the shot still looks grungy
repeat the process. I’ve never had to repeat the process more than
I use a low sudsing household detergent (very little, 10 drops or
less) & household ammonia (2 oz) when I tumble.
