Holy Cow-How does this thing work???? It is so cool! You literally take this small white sponge out of the box, wet it, scrub, and whatever was on whatever you're cleaning is GONE! Pretty much anything by Mr. Clean is OK in my book, but the Magic Eraser is just amazing!! It works better than most anything else I've tried-including those "miracle" cleaners you see on TV.
I have 2 big dogs and a cat-mud and who-knows-what gets on everything. Walls, Floors, Ceiling (I don't know how, either). I'll have kids over-they get crayon or other utensils on the walls. You set this small, VERY inexpensive, easy to use little white sponge on anything in your house (or outside for that matter) and it will be gone. No cleaning chemicals, minimal elbow grease. Even mildew on outside furniture. Showers, too! I still can't believe you get two of these for about a buck fifty.
now that I've sung it's praises, here's the only downside-they do wear out sort of quickly. For a big job you will probably need 2 or 3 sponges. (I'm talking like all your walls downstairs in a medium sized house, though)
My recommendation-go out and buy some of these NOW! LOL!!
