Frank,

My buddy's shop has this upright cabinet which runs heated detergent. Looks
like an engine sauna to me. No solvents from what I understand. My parts engine
parts all seem to come out sparkling clean after spending some time in there.
Works like a dishwasher I guess. I see the put whole engine case in there two
or three or more at a time and sometimes run them overnight. I can get the
brand and take some PICS if you want.
