Any rec'd for lab/tube brushes that have well behaves bristles? Don't shed. Flexes well to fit tight spaces gently. Also if they are soak friendly.
Try a home brew store. Wine makers and brewers have needs for many brushes that can be nicer than test tube cleaners or lab brushes.
Hard water is making scaling a problem to begin with. If I used to much PBW and it is causing salt looking deposits. Can anybody rec;d something to peel that off.
I have heard from people here that CLR has worked.

CLR&reg Pro Industrial Products Frequently Asked Questions

How do I clean hard water deposits from my drinking glasses?
Pour 1/2 warm water and 1/2 CLR into a plastic bowl and dip a clean, soft cloth or sponge into it. Apply to deposits and rub. Rinse thoroughly with cold, clean water. If it seems that CLR helped a bit but the glasses are not completely clear, repeat at full strength if necessary.

FYI on water temps:

feds recommend 120 F max on water heater temps. Some folks go higher but 130 F will give you third degree burns after about 20 seconds of exposure.
160 is mofo hot.
I preheat my water piece with hottest tap water and then mix PBW externally with distilled water and fill piece---want to avoid any chance of hot water shock cracking my glass.
I used to use distilled for day to day in bubblers but got lazy. Still do for cleaning to make sure the PBW mix is "the best it can be". If I had hard water/well water, I'd use distilled day to day.
Distilled water is cheap insurance.

I don't understand why some of you are dissolving PBW separately before use??

After that the oxygen can't work anymore on your glass!? And as said some posts before the oxygen is a very important factor of PBW for cleaning efx.

I preheat my glass with hottest tap water to prevent thermal shocks, empty the glass then I fill in immediately the PBW and add boiling water. Some shaking for dissolving the PBW and let it stand for around 10 minutes. Works awesome every time.
If your fingers are too heat sensitive use a silicone glove or something like that.

PBW makes glass so damn slippery, I'm all about letting some pieces be as stationary as possible in the cleaning process.
Others I do as you say.

With premixing, you can just pour it in and let it sit, then rinse and that's pretty much it.
If I was shaking around, I'd probably prefer salt + alcohol

It's similar to Oxy-Clean for clothes washing machine. They recommend filling machine with water and dissolving the powder BEFORE adding clothes. We're talking you miss out on what, 10 seconds of oxy action??

Mixing externally, you also can get MUCH more vigorous in making sure it is dissolved, heavy shaking or heavy stir action.

Putting raw powder into bubbler and adding water, the powder can float up before fully dissolved and that white paste particle get into a perc etc.
It's that white pastey , not fully dissolved PBW that can leave white stains.

For a $20 bubbler--meh/ok. For a $400 bubbler, I would never mix inside the bubbler as it is not worth the risk.
Err on too little PBW, too short a dwell time and repeat if necessary rather than over-do it :)

I am looking for some first time advice here. I grabbed some of this to clean a stubborn spot on my Mobius. How much should I use? You pour some in the glass and then add hot/warm water and let it soak? Or pre-mix and then pour into the glass?

The less the better, the hotter the water the better.

I use about 1/2 tsp to 500mL H2O (straight from a kettle), and I think that's quite concentrated. I have used as much as 1tsp but I think it's too much. For cleaning cheap combustion pieces that's my go to, but for Mobius glass I recommend less and multiple washes.

You'll want to bung the joint and externally mix PBW, stir thoroughly so it's fully dissolved.

Then fill the piece, rotate it around so airbubbles aren't causing dry spots and the piece is completely full.
Let it sit 5-10 mins and repeat until clean.

If the spot is accessible, some scrubbing action will make short work of it.

If it's inaccessible, expect to be doing multiple washes, but it should eventually get it.

I want to thank everyone (too many to name, you know who you are) that have contributed to this thread. I have been going through some serious life changes and have not been able to be here for quite some time. I really appreciate the level of support the community has brought here, its a fantastic testament to the quality of people here at FC.

While I still have very pressing medical issues, I will still try to peek in here from time to time to be with my friends . . . :peace:

Best of luck, brother. Let us know if we can support you in anyway. You are a really good guy and have all of my best wishes for a speedy and full recovery.

@t-dub ^ditto, once again I find myself nodding to a @Baron23 post.

You don't know me but I have learned and laughed much at your posts in many threads round here. A benefit of being new is years of FC gold to be mined. Certain people are there year in and out, holding down the fort and growing the legend. You are one of the quality people that made me keep coming back, you are part of that fantastic testament to the kindness and sharing knowledge with those searching that's in the culture here. No doubt you are one of those who were instrumental for me successfully fuck cannabis combustion.

I hate that medical issues are messing with your life, that just plain sucks. You've given a lot here so if there's anything you require I hope you'll let us know. I also hope things turn around for you real soon!

@t-dub Best of health and spirits and a speedy recovery. Remember when you mentioned your thread and PBW to me and made me a convertee?

Currently I have a Pyrex saucepan that is used for the PBW mix. My pieces are already heated and flushed with water. So I drop a tsp into the boiling water and let the crystals dissolve and fully react and then pour a small amount into the piece and flush it with the hottest tap water and repeat.

The pieces that have the residue. Well my flush and boil method got rid of most of it without compounding the problem. But some residue remains. After a few applications and ISO rinses, I could perhaps bring it back to spotless. :hmm:

Clean glass means less materials can stick the glass and to any materials that are already stuck. It has gotten better to predict where the problem areas will be. Meaning less fuss and muss on my next glass cleaning day.

Thanks again @t-dub for helping me get more studious about all this. :tup:

Getting better at removing the old PBW residue and making better boiling batches. First I clean and flush whatever wants to come out. Then I set it under the tap at the lowest running hot water setting and allow the glass to become heated. Later apply the boiling PBW mix. Rinse. Shake some ISO and rinse, Shake some Lemon juice to remove the stubborn residue. Perhaps some orange environmentally friendly soap. PBW Boiler batch and final rinse. ISO to sanitize.

Using less PBW to get the job done and trying to use safer products to assist. Would Baking soda add anything to the process?

Not just dissolves better but it cleans better because you are adding energy to the cleaning cycle . . . :)

Really like the image in that quote..Other considerations. Energy, water flow (laminar or turbulent). Heat of glass at time of adding the PBW boil solution. Water flow from your faucet with your setup.

Clean glass is easier to keep clean. Avoid buildup. :2c: Use as little materials as necessary to do the job.

I do use a chemistry brush and had to for a few hard cases. :peace:

I seem to have the same problem as many in the previous page, etc...
First I got some strange marks, they are round, running along the sides of two of my pieces.
I'm guessing from soaking with cleaning agents in cold water (or that went cold) because I'm very OCD with glass.
Used everything from Crystal Clear to GO, ISO 100% (gently) with a little salt (different grinds) and without, boiling water, you name it..! Seems the more I use a piece the harder it becomes to clean.
Then I tried PBW but it left those white streaks :doh:, both inside and outside every piece I cleaned it with. Although partly it is my fault for letting it go cold, when I was working on the other piece and vice-versa.
It seems to happen when it dries up, even if rinsing thoroughly?

Well, I don't know if I'm reading too much into this, and hopefully somebody with more common sense (and probably a degree in Chemistry as well! :p) will hopefully deter me in time...
So I read brewers also use a 5-10% acid solution for rinsing after the pbw wash, apparently?
Caustic Soda (Sodium Hydroxide) is supposed to remove any organic residue leftover if I'm not mistaken.

I took a look at other stuff they had in the shop and bought (yes, I did communicate with two reps before ordering) the said Acid solution and Caustic Soda (Sodium Hydroxide) along with the PBW just in case...

Added adequate protection: corrosive-resistant gloves, glasses, suit, aperon, gas mask, 2-3 layers of clothing, long sleeves... Operating in the balcony to avoid toxic fumes inside...

Will be trying the "nuclear solution" later on this week. :worms:

I noticed similar stains on the inside of my Incycler. I ended up finally getting them off with a hot vinegar soak followed by adding some baking soda. Not sure if the baking soda was needed but it worked!

Sodium Hydroxide didnt do the trick for me.... even tried soaking for a couple of weeks with it. white marks from PBW are still there

That’s right. Vinegar essence FTW!
Always does the job for me after PBWing- even when citric acid fails.

PBW and then vinegar can make ISO obsolete. At least in my glassbook. :)


Good luckx

I have LIME STONE FLOORS and vinegar does the job!
