Best way to clear slow bathroom sink drains?


My bathroom sinks drain slowly due to a build up black waxy/sticky material that collects in the drains. Is there a safe, easy way to clean unclog a bathroom sink without taking it apart?

    My first thought would be to figure out what the black sticky buildup is. I have always cleaned my drains by pouring baking soda (I use 1/4c per drain) in the drain, followed by white vinegar. I usually let it set for about 20-30 minutes then run hot water down the drain. If you have quite a buildup it make take several rounds to get it all to break down and flow out. Hope this helps. Good luck!

  • You can buy a long plastic drain cleaner for about $1.

    Get the plastic drain cleaner with barbs on it, it will remove any hair that is in the drain. Frequently the gunk collects on the hair and builds up. Once you get any hair you have in the drains, Gina's suggestion is the way to go to clean up the greasy gunk caused by soaps, shaving cream, etc. going down the drain. If you have double sinks, do both at the same time. After letting the baking soda and vinegar work, I follow it with about a gallon of boiling water between the two sinks to rinse the drains down well This should get them draining again. The black color could be mildew or something and the vinegar will take care of any bacteria and mold or mildew spores that are present. I hope this works for you, if need be repeat it. If you do this to your sinks on a regular basis the hair and gunk won't cause draining problems. This works in every sink or shower, bathtub, or drain in your house, but the hair remover isn't necessary in all.

    Pour 1/4 C. of Dawn liquid soap down drain and wait about 1/2 hour then followed by boiling water. It has always worked for me.

    First pull any hair etc. out of the top of the drain.
    Look under sink. You will find a U shaped pipe that is held by 2 rings (one at either end of U). Place pail under the U piece. Unscrew the rings. Pull down U piece. Now clean out the U any way you see fit. Place U piece back on pipes and tighten rings.
