Cleaning tomato sauce stains out of plastic
I stored some homemade tomato sauce in a plastic container, and it appears completely stained red now. Normally, I wouldn't care, but this is a very nice Tupperware container so I would like to get it clean. I tried scrubbing it, soaking it, and also tried the Mr. Clean magic sponge. Nothing has worked. Is there a sure fire way to get rid of the red stains?
