PGA is pure grain alcohol, such as Everclear or high quality vodka. I prefer to use PGA over distilled water. How much to use really depends on the juice. Start with a few drops & shake it up good. If you have a juice that you think wicks well, take note of it's consistency. Try & thin out the others based on that juice. The good thing about PGA, is that if you do go a little too far, you can leave the bottle open, & it will evaporate. Try not to thin it too much though!
AG, I gotta say, love the name, and 5,000 post in under 6 months is DAMN impressive.
