I saw this on “WeedInAPots” YouTube channel, tried it out and figured it was to good not to share. Take a sponge you would use for washing a car then cut it a bit bigger than a glass or small mason jar. Put some iso in the glass, then you can stab the sponge with the trimming scissors every so often. They trimmers come out with no resin on them. If you used a mason jar and have more trimming to do put a lid on the jar then you can use it when you trim again. The only down side is no scissor hash.
