Angry Mama Microwave Cleaner is cutely designed, the idea is stop put vinegar and water in it, place it in the microwave and the steam is supposed to lift all the dirt. However we bought it brought it home, filled it and put it in our microwave... we heard a strange sound .. kinda like a sizzle and now our Microwave does not work. I contacted the company and they offered to replace the product.. the product survived, However Angry Mama broke my Microwave.
