I gather up the brushes that need cleaning and off I trek
walk down the hall to the bathroom with my makeup brushes, a towel and cleanser. One by one, I put each brush under the tap of warm running water, apply some cleanser and swirl the brush in my hand (technical bit) and then rinse until the water runs clear. Always making sure that I hold the brush at an angle so not to direct the water into the base of the brush. Some spendy MAC brushes have met their end that way...
I'm not too fussy when it comes to what product I use to clean my makeup brushes. At the moment I'm using plain old baby shampoo. It leaves the brushes super soft without leaving any residue behind. Once washed, I reshape the bristles while they are still damp and then lay each brush on a towel or flannel to air dry overnight.
Brush cleaning, the only kind of laundry I don't mind! Has anyone tried using the Dr Bronners 8-in-1 Magic Soap? How do you clean yours?
