Our Wipeable murals work with Crayola Brand Washable Markers, or Crayola Brand Washable Paint. Most fairs we work with use the Markers, as they're cleaner, easier to manage, cheaper than paint, and easier to wipe off. If you're indoors over a floor you need to keep clean, markers are your best option. They wipe off with water and sponge or even a water spray bottle and paper towers. the mural out overnight on a stand in the wind.
If you're outdoors, or in a place where the floor isn't a concern, you could use paint or markets, and wipe it off with a bucket and sponge, or even a hose.
We highly recommend cleaning it off every day to avoid staining. We've had some Family Entertainment Centers and small Theme Parks who used it and wiped it every day for more than 700 days. DON'T use any soaps or cleaning products. You can use a regular hose with a trigger sprayer, but DON'T use a pressure washer.
