As with all 2 year olds, our rugrats took a crayon to the wall. So, Mr Clean to the rescue. It got rid of the crayon very well. No traces left. And then I discovered that she also took a pen to the wall. And I cried a little. Mr clean WILL take the pen off, BUT a lot of scrubbing is required. With my carpal tunnel, it's impossible for me to do. The only negative aspect is that it falls apart fairly quickly (not very durable).
