General waste bin or glass recycle bin or neither?

I have some decade old, gruesome tall thin glasses infested with mold and food residue, cloaked in a grotesque and sticky film of decaying death that… are in no easy way to clean. What to do with them?

I think it might be dangerous to workers when put in the general waste.

    There are ways to clean glass passively, it sounds like your residue is organic.

    • acetone, the pure kind you buy in a tin can at the hardware store. it will require some form of sealed container to put the glass in (acetone evaporates quickly and eats almost all organic matter) - finding a container big enough for your glass might be the hard part of this but it works (soak for days, and do not touch acetone with hands or use organic gloves - internet search for proper gloves)
    • ZAP heavy duty citrus cleaner, comes in a gallon jug. soak the glass in it for days or longer, doesn’t need a sealed container. This is the same stuff you can use to clean your sink drain and is pretty safe to handle but still, wear basic gloves just in case.
    • high-purity (like say 70%) iso alcohol with table salt as an abrasive (standard grocery store things). This is more of for the inside, where you can put in alcohol + salt and seal with your hand and vigorously shake to let the salt scrub the residue and the alcohol to eat it. Uses a lot of alcohol due to it’s evaporation, so buy a bigger jug.
    • specialty products found on 420-friendly websites or your local 420-friendly store; weed residue is a thing for bongs, bubblers, pipes and any other sort of smoking apparatus and they need cleaned and are hard to get inside; products are made to soak the glassware in to try and get the junk out. generally expensive and hit or miss on quality but they exist

    Hope this helps. (edit: acetate -> acetone, oops) (edit2: 90% -> 70% alcohol per comment)

      A note on alcohol as a cleaner:

      ~~Alcohol is actually a more potent solvent when in solution with water. 70% isopropyl alcohol is so prevalent because it’s actually more effective than higher concentrations. ~~

        Idk how true that is, it’ll be highly dependent on what you’re trying to dissolve.

        This sounds to me more like the advice I’ve heard for using isopropyl for sterilizing equipment and surfaces, its more to do with how quickly the pure stuff evaporates. Evaporate too quickly and it doesn’t sterilize, whereas 70% is best of both worlds.

          Furthermore, for sterilization 70% is more effective because the other 30% is water, which helps ensure everything is exposed to isoprop for long enough and bacterial cells take in the isoprop and die (because water passes through the cell membrane, taking isoprop into the cell with it), rather than ‘hunkering down’ and surviving until the solvent is gone

          However for cleaning electronics, the water content is bad because it does not dry quickly and can cause corrosion, so 99% is needed

          So the percentages have varying uses and should be chosen based on the task at hand

            At the quantity the OP might use, buying by the gallon might make more sense - having a look to Amazon, the popular concentrations in gallon+ sizes are 70% and 99.9% (about the same price, $25 USD/gal) - it probably makes more logistical sense to go with 70% here to reduce evaporation and increase usable liquid on these tall, thin objects (so let’s say “sloppy use” of oddly shaped hard to handle glass).

            I’ll leave my update at 70% concentration as the more economical choice - I’d presume based on their comment a soak in ZAP ($18 USD/gal) first is needed, then followed by the iso method… so it’s a little expensive no matter what for something they might not care about that much.

        This does not apply to electronics. You want that 99% to leave as little moisture as possible.
