8. Makeup sponges
Makeup sponges can host a lot of enemies. The real problem is that a Anisa International survey found that more than half of people who use makeup brushes clean them less than once a month, or even, not at all. Toss your makeup sponges in your washing machine in order to prevent bacterial growth.
“I put my sponges and velour puffs in net lingerie bags and put them in the washing machine on the gentle cycle with an extra rinse cycle,” celebrity makeup artist Kathy Jeung told Glamour magazine. “Add some beauty blender cleansing solution and Meyers laundry detergent, and voila—thoroughly clean sponges.”
