Razors: If you want to make your blades last longer, don’t store your razor in your shower; instead opt for a cool, dry place. But even if you take perfect care of them, razors should hit the trashcan after six or so shaves.

Sponges: Your sponges can last up to three months, if they’re high quality and you wash them after each use. As for the drugstore cheapies, toss them after one application, says Cromwell.
