Real Techniques Brush Cleansing Palette: “Great makeup application starts with a clean brush. The brush cleansing palette helps sweep away makeup, oil, and impurities from bristles to give you truer, more consistent color application.” I have used this palette with a range of brushes and M·A·C Brush Cleanser fluid and it works better than any other brush cleaning method. I have yet to try Real Techniques Brush Cleansing Gel.
