I think we need to clarify something here. The original question was in
regards to a "dishwasher" type batch cleaner using a saponifier. There
also exists "semi-aqueous" equipment that can be used with solvents
like Bioact EC-7 and IPA. Under no circumstances should you attempt to
clean in a "dishwasher" type aqueous batch cleaner using solvents.
There could be a fire or explosion hazard.
