I read somewhere in this forum the other day about some people using Magic Erasers to clean the window in the door of their MES. I hadn't heard about them and asked what they were and received replys. Anyhow, I looked at my grocery store this morning and saw some. Now, the problem here ... I assumed there was "one" Magic Eraser, but found the store had "FOUR" different types of Mr Clean Magic Erasers, so my question is ... those of you whom uses these things, which one do you buy? I bought the one that said "Kitchen & Dish Scrubber" with a picture on the back of box of baked on whatever on a metal pan. It was the more expensive ($2.69 ... 2 in a box) of the 4 types on the shelf.
