Has anybody towed around with using xylene or toluene as the non-polar in the iso/naptha procedure, the reason why Im asking is because

the returns are being listed as 70% with further cleaning needed , Im curious if using xylene instead of naptha would reduce this need for further cleaning anybody have any input?

Swim uses a conglomeration of parts of different cleaning dreams, and swim has been using Xylene for a long soak, followed by most of the thing you posted, and finishing with the egull thing. swim's been getting higher yields with each attempt, and is now approaching 50%-which is much better than the 5% swim started out getting.
