Folded and organized a bunch of plastic bags just now.
They dried nicely overnight. I washed most of the ziplock bags yesterday and will clean the others today. It's nice to work through the stack that have been waiting to be reused.
In true dull man fashion, I have a process: First let them drain upside down in the dish drainer for a few minutes. Then dry them with a thin towel. After that stand them (loosely) together with the opening facing up. (The orientation is important.) The last of their moisture will dry in a few hours (duration depending on how dry the air is). HTH.
