After you’ve worked the shampoo into the brush, gently run it under water and repeat the back and forth brushing motion until the water runs clean (and there are no signs of suds, either). With larger brushes (like for powder or blush), I also like to squirt a little shampoo into the center of the brush and really work up the lather. Brush the brush back and forth to absorb the shampoo and start to work up a lather/foam. If you use shampoo, begin by wetting the brush you want to clean with lukewarm water (never hot) and then dip in shampoo/cleanser. Always lay your brushes flat (or clothes-pin them so they hang with brushes pointed downward) to avoid water getting into the handle and ferrule (which can cause rust or deterioration of the brush). Often, an alcohol-based cleanser is a process that doesn’t need water and will also dry faster than cleansers that need water. For instance, Sephora’s Brush Shampoo works much like a shampoo and requires the same process, while on the other hand, shu uemura’s Brush Cleanser has you pour the brush cleanser into a small glass, swirl the brush in it, and then press the brushes against a towel to reshape. Some brush cleansers require water, others don’t. I know, that sounds way too basic, and almost like a cop out, but brush cleansers vary in technique. If you use brush cleanser, read the instructions. Shampooing requires at least an eight hour window for drying (a little less for eye brushes, a little longer for denser, larger brushes) brush cleansers are often alcohol-based and can be used as a spot cleaner between applications or dry within minutes as opposed to hours.

Either method works just as well–it depends on what you like. You can also use a mild shampoo that’s designed for human hair as well. There is a slew of brush cleansers designed with makeup in mind from just about every brand that also has brushes (and some that don’t!). Start by choosing either a mild shampoo or brush cleanser.
