evidently xylene will work as well, never compared the two- but others have said it works ok. Swim only ever experienced naphta -with excellent results.
He learned that the best way to deal w/the emulsions was not to form them in the first place- gentle with the first pull/wash/defat what have you, and then more agitation on the second etc.
Time and/or gentle heat can work wonders for breaking them emulsions- most definatly NOT more agitation (swiy already knows this, but it has to bee said, as swim knows how tempting it can bee to say 'its already fucked, so fuck it...').
Gentle heat....gentle heat....gentle heat......
ENJOY!
