Try this amazing trick!
Every use a soap-filled or plain Brillo pad to clean a pan and it’s still full of nice soap and you want to save it on the kitchen sink rim and the next day it’s all rusty and useless?
Next time this happens, put it in a sandwich bag, no need to dry, and put it in the freezer!
Next time you need it just take it out wet it with hot water and you are good to go.
Pro tip: Put a note inside that it’s a Brillo pad so you don’t accidentally think it’s hamburger.
