If you use makeup brushes to apply your makeup. You know that the process of cleaning your brushes can take hours. I usually wash my brushes with soap, water and a bit of olive oil. I usually have to let them sit and dry over night. Well, I discovered this product through a You Tube video. It cleans all types of brushes. The best part of this cleaning solution is it only takes 15 minutes to dry. Love this, a little bit goes a long way. Example, this particular bottle I've had for about 1 year. It's fantastic. It's called "Cinema Secrets" professional brush cleaner. I got it on-line. I don't use this every day, but I do use it once a week.
