This is the greatest brush cleaner ever! It lasts forever. It’s great when needing to use the same brushes for different clients, it sanitizes and cleans all brushes, even the most dense, within minutes. This is an m.u.a must have, Especially for freelance m.u.a’s working with multiple clients! I use this daily for thicker products such as pomades or gel liners, one dip and all the previous product build up disappears! I’ve been using this for years and will never switch up, I have yet to find any brush cleaner that compares. A little goes a long way! Smells wonderful too!
