Be sure that your shot is clean before you run. And be sure to use
fresh cool water and soap each time you run a batch. Some one once
compared it to a washing machine you would never re-use the dirty
water to wash clothes.
We supply a shot cleaner (750 compound ) as well as many types of
soap for the tumbler - different soaps work better on different
alloys There is a blue liquid that works well on platinum and a white
powder soap for yellow gold, some people even combine them - it seems
everyone has there own formula. But the more lubrication from the
soap the better and quicker the pieces will come out.
