This has worked very well for me as a daily brush cleaner. At first I was concerned it may break the glue down on my brushes but so far it hasn't. In this video my brushes hadn't been cleaned in about a week because I was waiting to make this video to demonstrate and didn't get a chance to make it as soon as I thought I would. So it took a little more cleaning than my usual daily cleaning. Also, for my larger brushes, I usually only dip the end of the brush in the solution and not the whole brush so only the tips of the bristles absorb the cleaner. Once a week I get the whole brush immersed to clean it thoroughly. Join me at MakeupTalk.com, the prettiest place on the Internet. As always, it's free and fun.
