Scrub Daddy is a practical cleaning sponge that changes texture depending on water temperature and can be used to clean almost anything. Rinse the sponge in cold water to use for tougher cleaning without scratching. (You can even use the sponge to scrub potatoes when it's hard.) With warm water, the sponge becomes soft and malleable and can be used for easier cleaning. Can be cleaned in a dishwasher.
