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.
Hmm, I think you’re right about sterilization vs gunk removal. Got those mixed up.
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.
