The Brush Tub has three chambers that you can fill with water or other liquids. You could use these chambers in multiple ways to help keep your bushes clean. You could use the first large chamber, that has a graduated ridged bottom, to rinse off dark colors from your face painting brush by gently rubbing your brush back and forth along the ridges to loosen your face paint more quickly and efficiently. Try to not rub the tips against the ridges to avoid fraying. You could use the second chamber to rinse off white and/or to reload your brush with a little more water as you paint. The last chamber could be used for a final rinse of pure water, or water with a little brush cleaner in it or a other sealers or activators.
