Try to keep my hairbrushes clean but major frustration with the tiny circle's that remain around the bristles. Happy to see thePhilip B Hairbrush Cleaner does a great job in getting these and my hairbrushes have never been this clean. The metal rake tends to bend and criss cross each other which is quite annoying. Maybe I'm "raking" to hard, don't know. Its a little expensive but for me its worth it.
