My friend told me about the magic eraser and said it was the only product she knew of that got crayon off walls. She wetted one down, gave it to her 3 year olds and had them clean up their own mess. I don't have much crayon on my walls, but it did get marker off my cheap wooden table. It also got scuff marks off my walls and doors, and cleaned the outside of my refrigerator easily (I have one of those textured fridges, so stuff gets caught in the cracks). The local news station's customer protection guy tried it out and said it worked as advertised.
The one thing it doesn't seem to do well is grease. I get these grease spots on my wall, and it did nothing for them, but neither does anything else I've tried, so I'm not too upset. It also doesn't do well if the dirt is thick (thick as in, I really should scrape this off).
