Oh woe is me…we have a 1.5 lb. tumbler made of black rubber. I
recently bought some stainless steel shot to work harden some ear wires we
are making. I noticed how much brighter and shinier they came out of the
tumbler compared to all the other sterling components I have in the
Studio. I was thrilled and thought why not clean all these beads, clasps
and chain bits up.
We filled the tumbler with water up to the stainless steel shot and gave
it a good squirt of regular dish soap. Left it going over night and in the
morning voila` !!! Beautiful bright shining sterling. This worked for
three nights, each day picking the clean pieces out and throwing a new
patch of dirty sterling in. UNTIL yesterday…I opened the tumbler
to find everything had DARKENED including the shot! I thought maybe there
was a chemical in the soap that didn’t ‘agree’ with the rubber but was
doubtful as it had worked so well before. Last night I tried a chemical
free detergent and this morning it’s even worse. Everything is black!
What have I done wrong and can I fix it ??? Any suggestions or comments,
like “you fool don’t you know x y & z about tumbling ?” I can take it just
tell me. I would love to get back to the clean shinny sterling of the
first 3 days.
