Take each brush and run it under warm water, then apply a small amount of shampoo - you might want to use baby shampoo as this is extra sensitive, and gently rub until you have a soft lather. After a few minutes, run each brush under the cold tap and rub the bristles to get rid of the soap. When the water runs clear and isn't coloured from makeup, then you know the brushes are clean.Any ideas on how to remove liquid latex from a makeup brush?

You can soak the brush in very hot water (almost boiling)this will soften the paint and make it gooey. Then you can peel the paint off. Also try using hairspray. This works for me when I am painting.
