No need to throw them away. I just scrape them off with the stir stick, wipe it down with a dry paper towel and then again with reducer on a paper towel and it’s clean for the next time.True that the lip of the can needs to be dry, and I would guess that it helps to use a tape with strong adhesive too. Orange Frog Tape worked great for me. The problem with the spouts to me is the waste if you throw them away after each use, but then again, I use disposable paint cups too and they go straight to the landfill as well.
