They should be fine if hand washed with warm soapy water and left to dry, and not left to soak or used in a washing machine or tumble dryer.
Awesome. They r so useful. I use mine every week for about a year and still going strong. I just hand wash with warm soapy water and rinse out and let drip dry. dunno what Barbra did with them...maybe let soak or in the dishwasher..?!
Look nice but disintegrate when you wash them!
