There are endless reasons bathroom drains slow down or clog up, from hairballs to goopy cosmetics. But a working drain is essential if you want to use a bathroom for some of its main purposes, such as washing your hair, your face or your hands.
Help speed up a slow drain by first pouring 1/2 cup baking soda down it. Follow this with 3/4 cup white vinegar. Don't bend over to watch this drain cleaner in action, though. These two substances, when combined, tend to foam and fizz, and even though this mixture is nontoxic, you certainly don't want it in your eyes. After about 20 minutes, flush the drain with very hot water.
