We use PGA everclear.
We blow out juice from atty, soak for less than 5 minutes. We use just enough pga in a very small glass bowl (like spice bowl when cooking) to cover 2-3 attys.
Pick up attys and drain, repeat filling and draining until steady stream (usually just twice).
Then blow out PGA from attys, and stand them upside down on paper towel over night.
We save the used PGA in a small glass jar, and reuse until it starts to discolor.
We also use some of this same PGA on the syringes after mixing, we pour some in a shot glass and pull it into the syringes, then shoot it into the sink. we dont reuse it from the syringes.
Thanks for the detail info.. I'm going to try that
