I love this!! I used to find cleaning makeup brushes so annoying that I would just wipe them roughly and wash them all together when I had time. But with this, you just spray, wipe, and let it dry. I was surprised at how well it cleans.
You can spray it onto a kitchen towel or regular tissue, both seem to work fine. It's small and lightweight, so it's easy to carry around. The scent is mild and not irritating, which is great.
You need to adjust the spray according to the brush size, so just spray carefully.
It's more effective on small brushes like eyeshadow brushes, but I think it works fine on big brushes too. If you spray well, wipe well, and let it dry properly, it feels great to use the brush the next day. I think I'll repurchase this.
