Rinse the bristles under water. Avoid getting water above the handle of the brush, which can loosen the glue over a period of time.
Swipe your brush across your palm with a gentle brush cleanser (my favourite is the Real Technique Deep Cleansing Gel). If you have more than one brush to wash, set each one aside after soaping it up. If using your hands doesn't feel thorough enough for your deep-cleaning desires, then you can slip on the Sigma Spa Brush Cleaning Glove or set the Practk Palmat in your sink, both of which have an insane amount of rubby nubby patches to really wash away grime in the grooves of your brushes. The only drawback: you have to wash the matt and mitt after each use too, to prevent bacteria accumulation. For the very soiled brushes or foundation brushes, I usually swirl the brush in a little olive oil and then use soap so that it actually cleans the brush intensely.
Continue to massage the bristles while running them under water until it runs completely clear. Avoid getting the handle wet.
Gently press on the bristles with your fingers to release excess water. Don't tug too hard.
Lay the brush or brushes flat overnight. Do not lay them on a towel as this can cause mildew. Instead, set the brush down on a counter, with the bristle part hanging over the edge. When the brushes are completely dry, fluff the bristles a bit. Your brushes are now ready to use.
