I know this sounds weird but I love cleaning products. I tend to stick to my basics though; PineSol, Windex, Comet, and Clorox Cleanup. When the Mr. Clean Magic Eraser Sponge first came out I signed up to get a free one. What a great marketing idea they had. I fell in love with this sponge and have continued to buy it and to tell everyone I know about it. It works great on scuff marks which is what I use it for most often. It's amazing, it has even removed permanent marker off a wall (a friend's daughter did this, not my kids). I've never written to a company to praise a product but I actually thought of doing it for this. If you haven't tried it yet you can get a free one here. The only problem is they don't last very long, they start to disintegrate pretty quickly (probably designed that way so you keep buying them.) I only wish this would have come out when my children were younger.
