In a preschool environment, recess outdoors is sure to be a messy proposition. Children have always loved to play in dirt and mud, and will take any opportunity to get themselves messy. But before they are ready for snack time, or before they bring their messes back into your building, what’s the best way to get them cleaned up? One idea is to have a portable sink handy, which can be set up outside. Portable sinks can be hooked up to an outside faucet if one is available, or it can be pre-filled. They have their own water supply tanks and waste water storage tanks, so you are free to take them wherever they are needed with very little hassle. They provide both hot and cold water. The portable sinks also come in a variety of sizes, and some of them are just the right size for young children to wash up after playing outside. Many of them come with soap dispensers for added convenience. Setting up portable sinks by the door and having your children wash up before coming back inside is a great way to keep everyone clean and sanitary. The children will be less likely to spread grime and germs, and will learn good hygiene habits in the process.
