In my earlier review of the da vinci brush I mentioned a brush cleaning soap that is manufactured by the makers of the da vinci brush. I used it for the first time a few days ago and was very impressed so today I washed a few more and I am very pleased with the results. The soap comes in a nice tin and I used it much like one would a round of shaving soap. It has a very pleasant citrus/lime scent and produces a great lather that one could almost think you could use to shave. I hand lathered and gently worked the lather into the brush and then very thoroughly rinsed the brush. Most of my brushes are silvertip and a noticeable brightening resulted. I recommend both this product and the vendor which is http://promakeupbrush.com. The cost is twelve dollars but if you purchase it with a brush I would think that the first time buyer discount may apply.
