While a soap dish with a built-in draining function (as several on our list have) can keep the mess down, you’ll still need to clean it properly at least twice a month or so. It’s easy enough to simply rinse and rub away excess soap and soap scum by hand, but it’s even better to clean it with a scrub brush using a paste made from one tablespoon of baking soda and one teaspoon of vinegar and then rinsing. Giving it this treatment will ensure you’ve removed all the grime and soap scum from your dish and help prevent the appearance of molds.
