The basics After washing your brushes, press out the excess liquid with this Anti-Bacterial Sponge Wipe-Off Cloth. The benefits Use this cloth again and again instead of paper towels! The uses A little water softens the stiff towel and makes it ready to use to press the excess liquid out of your brushes after washing. When finished using, rinse under hot tap water, ring out, fold up and leave to dry till it becomes stiff again. It's this stiffening of the cloth that stops the bacterial transfer. The bottom line London Brush Company Anti-Bacterial Sponge Wipe-Off Cloth is the "green" way to clean your makeup brushes.
