Now for the up-keep. Anyone would think I was talking about human hair... but no, brush hair needs taking care of too y'know (soon there will be brush conditioners... or maybe there is already, I don't know). In between uses (when I am not in a rush, or feeling particularly lazy), I turn to B.'s Make-up Brush Cleanser (£4.99), which I actually picked up a long time ago and it's still full, which again emphasises my lack of dedication to brush hygiene. I simply spray this onto a large oval cotton pad and wipe off the excess from my brushes... this also ensures I don't mix eyeshadow shades. Just the other day I went to put a pink shadow on my eyelids and got an extra helping of gold shimmer from the previous day's eye look. This prompted me to never miss this cleaning step again. I find you need quite a few sprays of this for one brush as it soaks up really quickly, thus I wouldn't recommend it for a full on cleanse.
How do you clean your brushes, and honestly, how often?
