Kids' art easels can quickly become the centerpiece of a mess. Luckily, since they're made specifically for kids, most of them are made to be easily cleaned. For any plastic or wooden parts of the easel, use a wet cloth to wipe away any paint, chalk, and markers. If the easel has a chalkboard, you can clean that by using a cloth wet with water and a bit of vinegar. A whiteboard can be cleaned with warm soapy water or a window cleaner.
