I really, really, really like Charlie’s Soap. I had been been tipping out a small, but practical amount of the detergent — which I use for all my laundry — into a working tub. (Yes, plastic; I’m going to keep using it ’til it fails.)
Well, I got down far enough in my bag to find a plastic measuring scoop. Helpful, but in the spirit of plastic disclosure, worth noting.
My laundry soap comes without a plastic scoop. I have a stash of plastic soda bottles that my irresponsible rebellious (not very) teens brought home and I fashioned a scoop from one of them.
