Makeup brushes. Us beauty lovers spend a whole lot of money on them — sometimes upwards of $50 per brush — but if you ask average brush users, they'd likely say they rarely clean theirs.

And that's a real big problem. Used makeup brushes attract bacteria like a flame attracts a moth, and that can lead to consistent acne breakouts, infections, or potentially worse if you're inclined to share them every now and then. For avid makeup wearers, once every 10 days should be the minimum.

But contrary to popular belief, cleaning makeup brushes doesn't have to be hard, expensive, or time-consuming. Watch Revelist producer Kala Riggins' video below to learn three cheap and easy hacks for cleaning makeup brushes.
