Run hot water through the pipes for several seconds every time you use your bathroom sink. This helps prevent a build-up of hair or other gunk, such as soap residue. Once a week, throw in a handful of baking soda or pour in some vinegar before running the hot water.
If your bathroom sink is starting to drain slowly, use a plunger to clean the pipes. You should fill the sink and plug the drain holes before you start to plunge. Lowe's Home Improvement recommends smearing a thick coating of petroleum jelly to the plunger's rim. This makes a tighter seal, increasing the suction to clean the pipes more effectively.
Use a chemical cleaner. You can buy these cleaners at a grocery store or big-box retailer. Read the bottles carefully to choose one that is appropriate for your bathroom pipes. According to Lowe's Home Improvement, they will clean out your bathroom pipes through the use of caustic chemicals such as sulfuric acid or lye. Follow the directions on the bottle carefully. Once the pipes are clean and the water is draining properly, run plenty of water to flush out all of the chemicals.
Clean the bathroom pipes manually by opening the trap, which is located under the sink. Lowe's Home Improvement says that many traps have a plug that you can open, which allows you to push in a bottle brush or straightened-out coat hanger to clean the pipe. If there is no plug, put a bucket under the pipes and unscrew the trap. Wash it thoroughly with soap and hot water, and clean out the pipes with a bottle brush or straightened hanger.
Things You Will Need
- Baking soda or vinegar
- Petroleum jelly (Vaseline)
- Bottle brush or straightened-out metal clothes hanger
- Chemical drain cleaner
- Hair is one of the worst culprits for clogging bathroom sink pipes. Instead of brushing your hair over the sink, mount a mirror on the back of the door and brush it in front of that mirror. Remove and clean the drain stopper regularly to prevent chunks of material from making their way down into the pipes.
