Impossible bong cleaning

This is why you clean your bong every day or two and don't let it get to this point. 

 

I'd soak it for longer than 12 hours in the simple green, try a couple days..may need to do several times.  Can also try any degreaser such as Zep.
 
Never heard of it not working on resin, I've cleaned pipes, bowls, etc. that were caked from years of use and no cleaning.  Hard water spots are more difficult to get rid of imo.

 

I would suggest against boiling, extreme temperature fluctuations are only going to weaken the glass.

 

have you thought of warming up the simple green? i had a terribly gunked up slide that would never get 100% clean in anything but warm/hot sg....just an idea.

 

Keep washing it everyday, eventually it will get cleaner and cleaner, and stop scraping at it with a screwdriver.  When you rub the glass with something like that you are scratching the glass, those scratches will collect tar and resin which will adhere better to those areas....it just makes cleaning more problematic later.
 
If it's pyrex (duran schott) glass, it will be fine if you put boiling water in it, if it's low grade glass, it might shatter.
 
@[member="marley"], hard water spots are a PITA so I've started rinsing with distilled water.  You need an acidic cleaner for hard water stains, but they are very hard to get rid of.  Perhaps try barkeepers friend, it's a powdered cleaner.  I work in a lab and can get stronger stuff, I've always wanted to try a mix of HCl and Nitric acid, we use this to clean glass coverslips for imaging, but I can't really bring my bong to work and i'm not trying to bring strong acids home (scared the bottle will break in my bag since it has to be kept in glass).

 

Ya I try and rinse out my glass with r/o, and only use r/o water to fill my pieces.  I've got really hard water where I live so had to learn the hard way.  I do buy pieces fairly frequent (used) and they often have hard water stains.  Most of my recent frustrations are from those experiences.
 
I'll check out barkeepers friend, thanks for the suggestion.

 

lol if nothing has worked yet try CRL it might work and should be safe since you can clean coffe pots with it.

I recently cleaned two bongs as you described. Boiling it fucked it up. You weakened your glass and cooked that shit on.

Heating simple green by boiling water and putting simple green inside a bowl that is heat resistant, inside the boiling water is what works best.

At the point youre at, id say acetone may work, but after boiling who knows. Boiling glass is a friggin terrible idea.i learned the hard way once as well.....

I cleaned a piece the other day that hadnt been cleaned in 12 years. It had so much shit caked on it the guy threw it away. It was one inch around the entire inside. I used simple green and soaked it heated and that shit that was rock hard came right off.

If you resort to acetone, which i dont recommend at all, dont do it inside, within 20 feet of any flame and for gods sake, and yours, dont pour it down a drain.it will eat your sink pipes. If you cant scrape that shit off with a screwdriver, i dont know what to tell you. I heat simple green the way one would heat a baby bottle and those pieces came so clean the friend took them on the airplane and they went with him through customs with no problems, since they looked and smelled new.

 

One of my buddys only use the  bug cleaner for windshilds, like the stuff that squirts from windshild wipers. Just soak it for about 24 hours, then empty it. Run some hot water and salt, or rubbing alcohol and salt, and shake it while its in there, you will need to cover the downstem hole, and the top hole and shake it very well.

 

I owe this blade a fuckton for showing me this method of heating up simple green. if anyone has a disc diffused slide, you know how much of a dick they can be to clean, especially cleaning it 100% spotless. after following the method, it came out like I hadn't seen it since I first bought it. it works. thanks again pokeskot247!!

 

Thanks for the kind words bro. Wish i could clean everyones piece for them just once. But if i did, id have to buy a stake in simple green cuz id make those bastards a shit ton of money haha

 

Get stronger rubbing alcohol (higher %) and salt with q tips. And keep shaking it up every 15 -30 minutes for however longSent from my iPhone using Grasscity Forum

 

I had an ashcatcher that was a gift for me.... but it sat for a year at a buddy's house. His roommate ended up using it, then didn't clean it afterwards. The water, resin, ash all seemed to have melded with the glass. Nothing touched it.

Until I left it soak, longer than 12 hours in Simple Green. Gave it about 3 days actually... then run HOT water thru the piece. Wear gloves, if you have to.

It will come clean.

P.S. Do not use the other Simple Green products. The garden-variety, plain-jane stuff is the safe stuff and what works.

 

have you tried PBW (powdered brewery wash)?  it's made to clean home brew equipment and i've heard it works great on glass, just an idea
