The cleaning soap for cosmetic brushes has a citrus fresh fragrance and is easy to use (I'm doing this): Make brush wet paint a little with the brush on the soap, lather on the palm of the hand and then rinse under running water. Usually a wash cycle, when brushes that I use for liquid makeup, two washes should be carried out enough. The brush smell after fresh and feel soft after drying. The soap also holds a relatively long time. I used to wash my brushes with baby shampoo, but since they were not nearly as clean as this soap.
