Cleaning your clay (food) processor tip: After conditioning some green clay in my processor today, I needed to make sure all the green was out so that future projects would not be green! After scarping and cleaning as usual, I wiped the inside with a paper towel and it still had some green on it. I poured a little mineral oil in and wiped all of the inside using a paper towel and then washed with dish soap to remove the mineral oil, and no more green!
