I want to use black wax (Apiezon W) to protect one side of a silicon wafer
during  70C KOH.  Since TCE seems to be frowned on these days, I'm thinking
about Hypersolve (a.k.a. n-propyl bromide of 1 bromopropane) as the black
wax remover.  Hopefully, I can then rinse in something like IPA and then go
to DI water.

Anybody out there have any experience in this area?

Thanks in advance.
