Mr. Clean - what is your trick?!! I have been using these magic erasers and cleaning like a wild woman! I use them on the tub, shower floor, toilet because my toilet cleaner left blue marks on the bottom of the toilet seat and the eraser got the marks out! I have used it on my dirty white cabinets and now they shine and lastly my white walls where my daughter colored on with crayons. They are wonderful and I will be ordering more when I get down to having just a few left in the package.
