Anyone have a step-by-step guide on using PBW with glass? I looked through a few pages of this thread, and didn't see anything laid out nicely. And how much PBW should I use to clean a mildly dirty D020-D?
Here's my process:
1) Flush piece with hot water (hot as you can get from your tap - you want to get your glass warmed up)
2) Drain water, quickly add 1 teaspoon of PBW
3) Add a bit of hot water (HOT as you can get) and swirl it around for a bit to disolve the PBW partially
4) Carefully add more hot water. Using Rubber plugs to cover the holes (Try to eliminate as much air as possible - you want water to cover 100% of the inside of your glass)
5) Let the piece sit for 5-15 minutes until the water goes clear again
6) Uncap plugs and drain piece ( CAREFULLY - PBW on the exterior will make the glass VERY slippery)
7) Quickly flush piece with more hot water (several good solid flushes with hot water).
Depending on the condition of the piece, I will repeat this process. For combustion pieces, it may take as many as 10-15 cycles to fully get the piece clear.
Nowadays thanks to cranberry extract, aside from a hot water rinse twice a month, I rarely need to do more than one PBW rinse every several months
Don't use too much PBW, and don't let air bubbles form inside the piece. You may encounter a ring of white buildup if you're not careful. Don't worry, if a white ring forms (or a scratch inside the glass is now white), simply do another 5 or 10 PBW rinses, but cut your PBW use in half
