PBW & the Chemistry of Clean

Using hot water will not cause problems, as long as you don't immediately flush your glass with ice-cold water.

Like most all glass, going from very hot to very cold will cause the glass to shatter.

The only exception I can think of to this rule is the prince rupert glass drop

Cool stuff. Would goin from super hot tap water to super hot cold water be enough to damage the integrity of the glass? I did this on all my other pieces, but am going to be more carrful with this new piece.

I wouldn't do that. Even going from room temp to hot water (not boiling) I've seen glass shatter. Thermal stress from really hot to really cold just seems like a disaster waiting to happen. Wouldn't want you to break your glass!

What do you mean by rubber stoppers? I don't have those, but I was planning on just filling up and slowly and carefully swooshing the water around for a few minutes. This piece is going to be difficult to fill up all the way.

In the past I would usually clean my daily driver once or twice a week, and would cost me a bottle of ISO every couple times. This stuff seems a lot cheaper. Besides the white lines if left to sit to long, are there any other drawbacks? Any toxins in PBW?

My local headshop also have me a sample of KLEAR which I haven't been able to find much info on...anyone know how this compares to PBW?

Ratchett makes some wonderful stoppers which allow you to fill the bubbler 99% full to soak all the interior.

Just like the three bears--papa bear, momma bear, and baby bear sizes.
without these, you cannot soak the neck

Lol, Yeah, I've actually got two new tapered plug sizes since I shipped yours @MinnBobber - I've remade my medium-size plug to produce a smaller taper ratio (was a 1:20, now using a 1:12 taper) - I currently have 5 different sizes of tapered plug molds!

I'll be adding the new medium size to my store sometime this weekend.

Going from room temp water to hot water can cause thermal stress? Wouldn't that be happening everytime you put hot water through a piece to clean it?

I'm using the PBW without gloves, works fine, not that slippery for me as long as it all stays inside the piece.

@Ratchett where can I view your store? I want some stoppers, I need all sorts of sizes for all my pieces.

My PBW is just sitting at the bottom of the piece, it's not dissolving...the water is basically clear. What am I doing wrong?

You might be either using too much chemical, cold, hard, water, or some combination thereof. Are you doing anything to combine the chemicals at all like filling with water under pressure? Or do you just expect it to fizz up like Alka-Seltzer? If it needs help mixing, give it some help.

What do you mean by chemicals? I simply put the PBW granular stuff in a beaker of hot water, shake until the water looks cloudy, and pour it into the piece...after 5 minutes the water is clear, and there are pieces of the granular sitting at the bottom of the piece.

What is the water to PBW ratio supposed to be?

Try reading the package.

Sounds to me like its rinse time. Don't worry about the extra grains. Depending on the quality of your source water not everything may dissolve. Get it down the drain and be done with it. Rinse well. Inspect your glass for cleanliness, repeat if necessary.

The package that I have says 1 package for 3 gallons. I am using tbs and maybe 12ozs...

I am rinsing well but after reading this:
I'm late to post this, but the main ingredient in PBW aside from basically oxiclean you can imagine as microscopic metal bombs which eat grime. PBW should not come into contact with any metal or plastic you care remotely about because it is designed to eat away to pure metal. I would not wash anything metal like a screen with PBW.

I noticed my jar says something about an overnight wash? can i take a larger piece and just fill it up with pbw and water and leave it in a bucket, clean it in the AM?

Does this mean that there are microscopic amounts of metal left to rinse out?

Is there anything harmful in PBW? I am doing this all in my kitchen sink, I am sure there are microscopic amounts of PBW on the sink and sponge that I clean my dishes with...


Sorry if this is over paranoid, just tying to be safe.

I can't say too much about the post you cited without breaking the "be nice" rule. After reading this member's responses in the negative feedback thread, I would take anything exit has to say with a HUGE grain of salt . . . what she says, is in fact, wrong. The manufacturer and the science dispels all this "metal eating" crap hysteria and more. Learn the science, make some clean for yourself.

I should have worded my question better, does the PBW leave microscopic pieces of metal behind? Let's it wasn't rinsed all the way, would I be inhaling microscopic pieces of metal?

I'm not worried about the PBW eating my metal sink, common sense tells me it won't win that battle.

But is PBW safe to use in my kitchen? You say the word chemical, and I freak out. I cleaned my piece in my sink, and plan to put the beaker I used in the dishwasher, also my sponge got some PBW water on it. Knowing that my sponge and sink come into contact with dishes that I eat off of, are there any risks to using PBW in the kitchen? On the package it says it's safe and environmental safe, however it has a poison number on it...

If it did home brewers would not use it. Please stop tormenting me with inane fears.

Arrrrrgh . . . .

Hey I'm just trying to ask questions, what might be a ridiculous question to you is a real concern for me.

Am I the only one who uses PBW then if anything is left ISO/salt? Seems to be the best combination for fast cleaning
That's what I need to do, before my next RooR photoshoot. I forgot the salt rinse and there's a bit of residue coating my recycler, I've been meaning to do another light pbw followed by a salt rinse this time.

The dust and direct flash didn't do it any good either :p

I do the same thing.....every few days iso and salt and tons of water in the bathtub.....and maybe 2-3 times a month a good pbw soak......but im not doing tons of dabs so my 2 pieces aren't all that dirty......

@Jman5280 Use PBW with confidence. The word chemical is appropriate. BUT by definition WATER is a chemical. A Chemical is defined as a substance with a constant composition and cannot be separated into its components by physical separation methods.
This stuff was made for the brewing and food service industry. Follow all labeled cautions and you should be fine. FWIW I use a couple of small pinches in a piece and HOT tap water. AFTER ISO wash. This removes the residual sticky from the resiny ISO. Then rinse and fill with distilled water. Then vape away!
