Milt F. my good friend
Good to hear from you again, here's my answer to your question.
I leave the shellac item in a glass container, full to the top with
Methyl Hydrate and place it IN a soni-cleaner. By leaving it IN this
warmed solution the constant sound waves are activating the solution
to a very fast clean-up...in minutes, okay! 10-15 minutes, maximum!!!
Remove the jar or beaker, and suspend the clean item back into the
soni-cleaner and this way it washes off ANY remaining shellac
residue that might dry hard. I will then immerse this cleaned item
and rinse it AGAIN in clean Mehtyl Hydrate back into the
soni-cleaner, just for a few seconds.
Behold, all of this will take no longer than 20 minutes, start to
finish! VOILA! ready for polishing..totally clean and with no traces
of ANY shellac..this is my method, I have been using this idea for
many decades, trust me, it works wonders!...Gerry Lewy!
