I do some small scale casting and have had some difficulty removing
all traces of investment from my casts. My usual method is just to
pick it out using a very fine needle probe and then lightly scrubbing
with a brush under running water. I was wondering if there is an
easier way that is less time consuming. I saw two products in the Rio
catalog which seem promising but want others’ feedback on use before
I buy. Both products require an ultrasonic cleaner which I don’t
have, but would be willing to purchase a smaller one, if that is
effective for my purpose.
The first is Blastoff Investment Remover, a liquid. The second is
Break-Away Investment Remover, a powder. Would either of these
products work without an ultrasonic? If you’ve tried either, I’d love
to hear about your experience and preferences. Or would an ultrasonic
be good alone without a specialized product?
Any other suggestions for getting those last traces of investment?
I’ve tried tumbling with steel shot which helps immensely but not the
whole answer. Thanks in advance-- I know I’ll come away with some new
insights into this. The Orchid forum is amazing!
