Pros: Cleans and sanitize
Cons: a bit costly
MAC brush cleaner is my favorite cleanser with my brushes. The packaging of the cleanser really sucks because you really waster a lot of products. But I found a solution!
Took a small spray bottle, you can get one from the travel section of walmart ( i used my empty bottle of fix +) and put the brush cleanser inside it. Your cleanser will last at least a month longer!
