Pour 1/2 cup baking soda down the drain, then 1/2 cup white vinegar. Cover the drain for 15 minutes (the fizzing action helps dislodge soft clogs). Flush with boiling water. Repeat if needed. This is much safer than bleach and more effective for soap scum and grease. The Verdict Bleach is not good for clearing drains. It doesn’t dissolve the materials that cause most clogs, it poses serious health and safety risks when mixed with other chemicals, and it can damage your plumbing over time. Reserve bleach for disinfecting surfaces—not for unclogging pipes. For a slow or blocked drain, reach for a plunger, a snake, or a biological cleaner instead. Your pipes (and your lungs) will thank you.
