hi poopeen, christ thats a shitty name to have to address you by----ive known people who have used it on sudafed and they say it works---others swear by it---i havent heard negative reports about it--so it would appear it does--do a little cleanse and see how it goes---ive got my own method and when your on something that works--dont change--they state that they can get a 98.3 percent return on it--and to me id have to see that to believe it--everything ive ever done shows me you lose 3% to 5% of the eph every wash--yet ive learnt that when everyone says im wrong--then i usually am--good luck

Between the two, alchohol and naptha boil, along with the xylene boil, then splashed with ketone, the povidone and glycol don't stand a chance if any. Cleanest stuff I've ever seen!

I have been trying to understand the relationship between isopropyl alcohol and naptha. Both have particular lazy characteristics. Iso almost refuses to dissolve pfed crystals unless hot and naptha is choosy about becoming miscible with alcohols, except iso. When you pour the boiling hot elixir off the top of the pill mass into your vacuum filter, the speed in which the crystals come crashing out of the filtered solution is amazing. There have been times that Swigotta has poured too much, too fast into the filter, allowing liquid to collect in the funnel for longer than 10 seconds and bam they fall out in the funnel before they make it through the filter. Then you have to take it apart and start over.

What I'm gettin at is this dynamic duo appears to be very selective. After the xylene crash, they're very clean. Swigotta does the xylene crash separately so he can filter and reuse it again.
