Q: How do you clean a makeup sponge?
A: Wet it, work a little gentle soap or dedicated cleanser through it, then squeeze under running water until it runs clear. Let it air dry somewhere open rather than sealed in a bag.
Q: Should you use a makeup sponge damp or dry?
A: Damp for a lighter, dewier finish, dry for fuller coverage. Damp is the more common choice because a wet sponge absorbs less of your foundation.
Q: How often should you replace a makeup sponge?
A: Every three months or so with regular use, sooner if it starts to tear or stops springing back. Washing after each few uses extends its life considerably.
