An alternative to low sudsing dish detergents is to simply buy bars
of plain Ivory handsoap and add a few very thin shavings to the water
in your tumbler (amount depends on size of tumbler – in my Lortone
45C, I use 4 thin shavings off the end of the bar, when the tumbler
is half full of water).
As for polishing your jewelry, I always recommend Cerambits as a
tumbling medium. Due to the kindness of several folks on this list,
I have found out where to get it again. It is made by Raytech, but
you order it through Kingsley North in Norway, Michigan
(800-338-9280, or www.kingsleynorth.com). They backordered a new
lot for me, and I am eagerly awaiting its arrival.
All the best,
