This spray cleanser is awesome for between full on cleanings with soap and water. I feel like the many reviewers saying this gets oily or coats the bristles too much are probably using way too much product. With just a couple of quick sprays onto the tip of your brush you can wipe away tons of product from your brush onto a tissue and have a pretty clean brush. This stuff is perfect for when you're using your brushes daily for new colors and want to quickly remove the old coloration on them to start fresh. I wouldn't use it to coat the brushes heavily and try to remove every single particle of product. Soap and water is better for that. However, this can't be beat for removing a lot of product on a tissue so you have a clean slate to use for your next color on a daily basis. I'd recommend using a regular cleaning method once a week or so for deep cleaning, and using this quick spray to clean off the surface of your brush so that you have a nice, clean brush to use with a fresh color and to quickly get rid of lingering surface germs or yuckies. My husband actually threw this into my stocking for Christmas on a wild guess and now I can't live without it. Every morning as I'm grabbing each brush I'm going to use I just spritz the tip lightly once or twice, rub on a tissue I keep out on my vanity and then I have a nice colorless, fluffy, clean brush to use. Just don't use too much! Spray once or twice right onto the end of your brush and you'll be amazed at how much color comes off onto the tissue.
