Great Stuff For Percs!
I recently got a waterpipe with a couple of percs. This piece is especially prone to getting dirty over time: there's a big white block in the middle that would get super dirty, and one perc in particular, a showerhead, would get so rez'd up that it'd clog completely within a few days of using it. But with a few drops of this stuff, my glass stays nice and clean, only the water gets darker over time. This stuff has a nice cranberry scent to it, most likely a primary ingredient, and doesn't give the water or smoke any taste.
