The Best Way To Unclog Bathroom Sink

Before we go on to enumerate some of the best ways to unclog the bathroom sink, let us first understand why bathroom sinks clog in the very first place.

  • Excessive usage: if your bathroom is being used continuously, there is a good chance that your drains are not able to work extra and the clogging happens because of it; mostly in the hot summer months.
  • The main reason for the clog is accumulated dirt along with skin flakes and hair that slip through the drain catcher and mix with the soap scum to bond inside the drainage pipes.

While this is slowly happening, you will see water draining out slowly. Once the scum dams the entire pipe, the drainage will be ultimately affected.

Is Sodium Hydroxide The Wonder Chemical?

Is Sodium Hydroxide The Wonder Chemical?

All the commercially available drain cleaners have sodium hydroxide or lye as their chief component. You could buy caustic soda from a hardware shop. Mix two to three spoons of it in a plastic bucket half-filled with cold water. Make sure not to use a metal jug because it can react with metals. You must also wear gloves so that the chemical does not burn your skin and mask to prevent inhaling the caustic fumes.

Drain the sodium hydroxide and cold water solution in the drain and wait for one hour for the chemical reaction to take place. The carbon dioxide that is released allows for the breaking down of organic gunk. Pouring one bucket full of water following it up will one hundred percent clear any blockages in the drain.

You Can Use A Wet And Dry Vacuum to Unclog A Bathroom Sink

This is the most mess-free way of unclogging the bathroom sink. Simply bring the hose of your vacuum cleaner into the drainpipe after unscrewing the drainage cap. You must try and fit in the hose of the vacuum in such a way that it fits the drain hole entirely and tight.

Now run the wet vacuum cleaner. Initially, you may hear a rather funny whoosh or whine and sounds indicating that you are breaking the clog in the pipe. If needed, you could pull and push the hose to be able to create a pressure a la a plunger.

Unclogging Using A Wire hanger

Unclogging Using A Wire hanger

A lot of people do not know how to snake a bathroom sink. One of the reasons for this is that a bathroom sink is different from a kitchen sink. A plumber’s snake is easier to use in the kitchen sink where the drain pipes are raised whereas the bathtub is only a little above the floor height.

It is a great idea to use a clothes hanger made of wire. Simple put the hook end of the wire hanger inside the drain and push it till you find that clog. Rotate it slightly to be able to mobilize the gunk and unclog the drain. You will be sure of having succeeded if the hanger hook came up clean without any scum attached to it.

Chemical Cleaners are easy to use

There are so many of them that line the shelves of the stores. You must in all cases, use safety equipment/paraphernalia like the face mask and gloves while trying to pour chemical compositions down your drain.
