dirty glass
I just got 18 LBS of dirty 104 glass rods for LE ( happy score) but I don't know what to use to clean them? Windex, or something stronger? Big thanks for this newbie

If it isn't DH, you would probably be fastest to pickle it in bunches. (Do NOT do Zephyr)
I use PH down from the pool supplies aisle of HD or wherever has pool supplies. More information in this thread: http://lampworketc.com/forums/showth...t=pickle+glass |
I would wipe it down first before useing the pickle.
salt/white vinagar should work, and may be on sale, a lot of stores have excess after building stock for Easter. i |
I put mine in the dish washer:hide:

Oh, & I also would worry about keeping it so I know what it is if it isn't a "yes, that is my 006" type color. |
If it is just dusty, wash it in your sink, dishwashing liquid, warm water, rinse, dry.
|
or wipe it down with alcohol and a paper towel

I keep a roll of paper towels and a squirt bottle of alcohol next to my workbench and wipe as I go.
|
Soak in Dawn and warm water, wipe each rod back and forth with a wash cloth or plastic scrubbie and rinse. Then to get them really clean and get rid of residue from the stuck-on disintegrated gooey rubber bands, clean with nail polish remover. Takes that crap right off. But don't get the oily moisturizing polish remover, just the cheap no extra junk added stuff. Acetone based, preferably.

I keep alcohol wipes next to my glass and clean as I go. You can put the wipe back in the container and use several times.

I put larger amounts (1/2 or more) in the dishwasher...top shelf ... with other things if they're there.
I keep 70% rubbing alcohol on my work table in the kind of containers nail techs use for polish remover. You push down on the top and it releases a little liquied into the top area which is slightly concave. I use this to do a pre-torch clean-up or even while I'm in progress if I feel I've gotten some dirt or oil from my hands on the rod. I know some people use white vinegar in lieu of alcohol. I've not heard of using straight acetone. I would think it might leave a bit of a film. But I think I'll try it since it's such a potent cleaner. |
Maria, where did you buy it that it was so dirty?
|
clean and go sounds like a winner thanks
|
Soap and water. Or the dishwasher.

For a large quantity of glass, I'll throw in another vote for the dishwasher. Easy and effective. For just a few rods, both alcohol and acetone work great. However, both are very flammable, which is an obvious drawback around a torch. Vinegar seems to work well without risking any fires.
Barb, to answer your question about straight acetone, it doesn't leave any residue. Back in the days when I worked as a glassblower in a research lab we always used acetone as a final rinse when cleaning glass, for exactly that reason. And we had virtually any chemicals we wanted at our disposal. (Have I ever mentioned how much I hated working with HF every day?) Brad |

Brad,
Thanks for the info on Acetone. Maybe I'll swap out the alcohol in my push-top dispenser and just do Acetone....except, as you say, pretty flammable and more so than alcohol, I think. I'll have to ponder this a bit more. That vinegar is sounding pretty good. But I'll for sure keep the Acetone handy in the arms-reach cabinet where it now resides. (My studio space is so small, everything's within in an arm's reach!) Cozy! Thanks! Barb |
Acetone is HIGHLY volatile, the flash point is -17C.
http://en.m.wikipedia.org/wiki/Acetone I would recomend not using acetone near ANY ignition source. Nail polish remover has an oil in it to reduce the volatility of the acetone solvent. |

Barb, what I said about acetone wasn't meant to be a recommendation for using it (although it kind of looks that way after re-reading it), it was simply an answer to your question about whether or not acetone leaves a residue on glass. My personal preference for cleaning dirty glass in my studio is 91% isopropyl (rubbing) alcohol. Check the label for the alcohol percentage. The cheap stuff is usually around 70% alcohol. The rest is just water. Brad |
If using vinegar to wipe glass, be prepared for the smell of pickles. Smell doesn't last but it isn't for everyone.

When I mentioned the nail polish remover, I just assumed that people would not use it anywhere near their torch! lol Edited to say: after the nail polish remover wipe down which is only for the dirtiest rods and getting off rubber band gunk, I wash with warm soapy water and Dawn. |
In the end I think the best answer is to use the least hazardous solvent that works. For a lot of common dirt that is just dishwashing liquid and water. For something a little tougher, alcohol. As Lisi said, rubber band residue usually requires acetone or the like. MEK may be required if you have some really nasty crap on your glass, but then, you shouldn't get stuff that bad on your glass to start with. (MEK will completely dissolve ABS plastic, which is the stuff motorcycle fairings are made from.)
No matter what you choose to use, do it in a safe manner. This seems pretty obvious but is worth mentioning since I once personally watched as an instructor at one of the largest teaching studios in the USA dipped the hot end of a boro rod into an open bottle of alcohol he had sitting on the bench next to him to clean it as he demo'ed. NOT exactly the best safety example to set for students. Later in the class that same open bottle of alcohol got knocked over and spilled on the workbench while people were working. Fortunately, nothing ignited... Be safe, not stupid. Brad |

I always wipe a rod off on my t-shirt before using.
