Cleaning out the sink is easy enough. But if you don't give it a good wipe each day, soap scum, hard water and even your makeup can build up and leave your sink looking dingy. Depending on what type of material your sink is made of, staining can even occur over time. But not to worry, a daily cleaning will prevent stains and keep your sink looking squeaky clean. Wiping the sink out each day when you finish your morning routine will save your arms a good deal of scrubbing, too. To guard against a dingy sink and stubborn, built-up grime, simply keep a sponge under your sink or in the medicine cabinet. Give the sink a good wipe as the very last step of your morning routine, and voilà -- the days of vigorously scrubbing your sink are over.
