How to keep your nice and pretty cotton dishcloth from fading or the colors running....
Before you use your dishcloth put it into a bowl of tepid water with about a capful of white vinegar. Let it soak a couple of minutes, block it as usual. Then when you wash your pretty brightly colored kitchen dishcloth it will stay nice and pretty.
How to block: Squeeze excess water from dishcloth. Re-arrange cloth to proper size and shape, put it on another towel and allow to dry completely.
