Although we'd like to think that accidents don't happen, let's face it, they do. Most children will draw on the wall at some point in time and if you're out of Magic Erasers, try using this kitchen condiment to clean things up instead. The fine folks over at This Old House share a little knowledge when it comes to crayon removal. Instead of using harsh sponges, let a little mayo do the work for you. Spread on whatever brand happens to reside in your refrigerator (homemade works fine too) and allow to sit for several minutes.
Wipe off (and and it's probably safe to say you should wipe your wall down with a general cleaner afterwards). The crayon is gone without any hard scrubbing or swearing, and you can go back to your regularly scheduled life — or make a trip to Target to buy an artist's easel for your little one!
