I always thought PGA is grain alcohol. I never thought of reusing it. I guess I figured it would pick up any germs and then transfer them. but I guess it kills the germs and doesn't get "dirty". Like water does. lol
Yep and it only takes a very small amount. I line up my bottles, pour about 1 inch of bottom in first one, replace cap, shake, pour in next bottle, repeat. Once they are all done, i leave the cap off and let any leftover alcohol evaporate. If there is very much left, I cap the last bottle and save the PGA to reuse. I only do that if I use it on clean bottles though. It really is inexpensive to use and beats the heck out of boiling IMO.
