I did do research. There is no step by step directions and it seems like all the information is scattered. I watched the PBW videos and read multiple post from @t-dub.
Perhaps be more helpful and reference some page numbers than sounding condescending.
Sorry, I misunderstood, you expected someone to 'boil it down' for you? Pass. Yes, t-dub is the man, he is wise, pay attention would be my advice.....if you're looking for advice.
I apologize for trying to help you. You fooled me with " Perhaps, I am doing it wrong. After some reading this stuff sounds like magic, but not in my case. "
And no, thanks, I don't want to compile a reading list for you, I hope you understand why?
I'm sorry you're not grateful, I'll try to remember......
Less is more with PBW, less powder and less dwell time to avoid white blotch stains.
I preheat glass with hot tap water. Heat some distilled water on stove to 160 or 170 F, vigorously stir in only 1/4 tsp .
Fill glass and only soak 10 minutes.
Rinse a couple times with distilled water, 1/2 cup shaken in bubbler.
Did your PBW totally dissolve? I doubt that and that risks white splotches.
Repeat if necessary.
Less is better
Hot hot totally dissolved powder
Good advice, for sure. Not sure where the OP got the lame 'use a huge pile of it' advice, that's what can happen to you with 'I read it on the web' I guess?
You're right, as @t-dub said so often, heat, time and some agitation are key factors. Like most chemical reactions, the rate is tied to those factors. OTOH, the tendency to etch the surface seems to be more related to the quailty of the glass and the time (temperature and agitation not so important?)?
Powerful stuff, but not magic. And not a solvent like ISO.
On the topic of agitation it's been my experience (and I believe lots of others here 'bouts) that sometimes mechanical scrubbing is helpful. You can boil your overalls, even with lye soap (which PBW is a cousin of) but sometimes you need to beat them on a handy rock as well....... In the ISO world, folks use salt for this (which doesn't dissolved in alcohols if they are pure enough). They shake it around to scrub the softened junk off. I find (dry) rice does this just fine with PBW. A couple of heaping spoons gives you something to 'shake against the walls' to scrub stuff off. It softens up some after a while, but works fine for several minutes.
Regards to all, save one.
