A week or two ago someone moved out of my building and left everything for the maintenance guy to remove.
I happened to take my trash out today and was looking everything over.
I happened to see a couple of ice cube trays sitting in a bucket they weren’t in the actual dumpster because there was no more room.
I grabbed two of them and they are currently soaking in water with a whole bunch of vinegar and then I plan to soak them in hot soapy water.
