I heard about this on a Westman Atelier Zoom event sponsored by
Woo in Charlotte. As I mentioned above I think Gucci Westman makes the best brushes and this is what she reccommends using to get the white bristles of her brushes looking like new. I spray it on my brushes and just wipe them on a towel. It smells like
Wine Away and works like magic. I've also been told to buy the big bottle and pour it in a glass and just let brushes that are really really dirty soak.
