So after playing this weekend with PBW I have found my perfect mix that when using as about a 2 hour soak and I will say - this stuff is amazing. It almost seems like it restored my glass. Pieces that had burn marks on them for years, like new. And they mean it when they say no scrubbing necessary. I did play with my mix though as far as the yield on the packet.
I bought a few 2 OZ packets on amazon shipped for 6 bucks. 1 Packet to a gallon of water did the trick for my glass (about twice the recommended amount for brewery equipment). Made my HT look brand new, got burn marks off my solo stems after years of heavy use, and made my percs shine on all my pieces. How long do you get a way with one batch? I cleaned 2 bongs, and HT, 3 solo stems, a few adapters, and a wand for an SSV. Should I change it now?
BTW - Cleaned the fuck out of my shredder too!
