Because of the good reviews I have carried away to buy, because I washed my brushes have always with hand soap or shampoo. But that has to be there and see conclusion, the purchase has been totally disbursed. It's much more "dirt" from my makeup brushes and I have a feeling that he has never been so clean. The brush feel after washing, like new. The smell does not bother me - although the soap smells like lemon, but if you do not use too much, then the scent evaporates quickly. Top product !!
