You wouldn't touch your face with filthy hands or fingertips - the same principal should be applied to the makeup brushes that you use on your face. It's recommended to clean the brushes every three to five months (or when you feel like those brushes are getting a little disgusting). I've tried a couple of different brush cleaners - one by smashbox and the other by MAC.The Smashbox brand cleaner ($15) is a spray on type. Instructions say to spray on a tissue and wipe away. This is intended as a sort of minor cleaner - to use between major shampoo cleaning of the brushes. So the directions are meant to give you a sort of clean. I bought this as a major brush cleaning tool because of the misleading name "Brush Cleaner". Initially followed directions, but this didn't get it as clean as I would expect (it gave a "so-so" clean, like when you wash your hands without soap) so I sprayed on a wet brush, rubbed gently with my fingertips, and washed away with water until the brushes rinsed clean.
The MAC brand cleaner ($10) is more like the shampoo application. This is the major cleaner - it cleans, disinfects, and conditions. You put a little on a wet brush and sort of wipe away the "dirt" gently with your fingers and water until it rinses clean. I've used this more often than the smashbox and prefer the MAC cleaner over the smashbox one. Cleaning with both cleansers can be done the same way as described in the next section.A more affordable option is using baby shampoo to clean your brushes. The important thing to look for when not using a make-up brand brush cleaner, is that the cleanser is a gentle liquid soap or shampoo. Anything containing alcohol may dry out your brushes. Don't soak the brushes in soap and water, this may cause the brushes to fall apart. Put a drop of the shampoo/soap in the palm of your hand, wet the brush, and stroke the brush in your palm. Repeat this until the brushes rinse clean. Squeeze out the excess water and lay out on a paper towel or clean towel to air-dry.
