This superior cleanser dispenses as a foam to help the cleansing ingredients work around each fibre of the brush without over soaking the fibre bundle. The bubble action cleans and helps the brushes dry within minutes. The foam not only cleanses, but also sanitizes while it works. This unique formula leaves your brushes cleansed, sanitized and fresh smelling. 50 mL. To use: Press the cap down to dispense foam onto the fibre bundle of the brush or onto a microfibre cloth or moist paper towel. Wipe the fibre bundle back and forth across the microfibre cloth or towel until the cosmetic residue is released from the fibres, and all foam residue is thoroughly removed from the fibres. Re-shape the fibre bundle into the desired shape and let dry. If over time a slight cleanser residue accumulates on the fibres, simply rinse the fibres under some clean water, re-shape and let dry.
