Unclogging a bathroom sink can feel like an annual ritual. Things make their way down the bathroom sink all the time: hair, soap scum, toothpaste, and chemicals from beauty and hair products, build up and create a wall of gunk that clogs your bathroom sink leaving a pool of water that just won’t go down. 


Before making the call to one of our plumbers to get your sink uncloged, check out our guide on how to unclog a bathroom sink. Instead of focusing on drain cleaning chemicals, some of these drain cleaning hacks are probably lying around the house already. With these tips, you’ll be able to easily combat the simplest of clogs in no time!

Wire Hanger: Start with this technique first. It will help get rid of any top layer of hair, soap scum, etc and determine if the clog lies deeper than the surface. The good news is this can be done with any old wire hanger you have lying around the house. Bend it to the correct shape to guarantee it can get down the drain without any problems. Then just fish out all the hair and scum you can get. After be sure to run some hot water down the drain to clean any excess and to test and make sure the problem doesn’t lie deeper.

Baking Soda and Vinegar: This method is widely known. Two of the most used ingredients for cleaning also happen to be perfect to combat clogs in your bathroom sink. Mix 1/3 cup of vinegar with 1/3 cup of baking soda. Immediately pour it down the drain, and let it sit for an hour. Together, these chemicals can break down the scum and residue that may be holding your drain hostage. After the hour is up, run hot water down the drain to finish up the whole process. This mixture will keep the pipes clean and in better shape. 


Baking Soda and Salt: Baking soda is such a powerful chemical because it can be used for so many different cleaning tasks. Mix 1/2 cup of each and pour it down the bathroom sink drain. After 15-20 minutes, pour boiling water down the drain to put on the finishing touches. This combination should be powerful enough to break through most blockages.

Boiling Water: When dealing with a slow draining leak, boiling water may be the best option for a quick fix. With this method, pour about 3-4 pots full of boiling water down the bathroom drain. Make sure they’re poured back to back so that there’s enough force to break through any blockage.

Wet/Dry Vacuum: This can be a hidden gem for getting rid of clogs in your bathroom sink. First, ensure that the vacuum is set for vacuuming liquids. Then, make sure that the back vent is also covered so there’s not a big mess to clean up. Next, you’re going to need to create the tightest seal around the drain. We recommend using duct tape or even children’s Play’ Doh around the drain and the vacuum hose to generate enough suction to rid of any buildup and blockage.

While our guide for how to unclog a bathroom sink has many simple home remedies, they may not always work. The clog may be much deeper or compact than originally thought. That’s when our plumbers at About Plumbing can come in handy. By contacting us online or by the phone, one of our trained technicians will visit to make sure that your clogged bathroom sink drain is quickly taken care of.
