Don't use mineral spirits in an ultrasound bath; the power level is
cavitation in the working fluid, which is intended to be water (small
amounts of additives
are OK). Just as you should never run the ultrasound with the tank
And the power level is high enough to cause local boiling; don't put
Windex (glass cleaner) makes a good ultrasound fluid; low residue after
it contains wetting agent and mild (***?) solvent.
Water, small amounts of added *** and soap, is a general purpose
For rust stains, consider using a plastic inner tank and some oxalic
will etch steel or stainless, so never use on ferrous metals). For
grease, consider adding
a dollop of waterless hand cleaner; it will glom onto greasy things in
the crevices and
make 'em rinse off. But the fluid turns milky, so you can't watch it
Washing soda (dishwasher detergent, OxyClean, it's all the same stuff)
is good too.
Vinegar, lye, and dilute ammonia can also be useful additives, but
probably not for
