How to Unclog a Bathroom Sink: 7 Methods

There are certain skills that every commercial and residential occupant should have.

From changing a lightbulb to patching a hole in the wall to unclogging a sink. These are all important things to know how to do but we think unclogging a sink is one of the most important.

So where do you begin if you have a clogged sink? And what if you don’t have a plunger? Not to worry.

We’ve put together a list of seven different ways that’ll prepare you when you’re curious on how to unclog a bathroom sink.

1. The Wire Hanger Method

This is the classic, tried-and-true method when it comes to unclogging a sink.

Take a wire hanger and straighten it out as best as you can. On one end make a small curve that can facilitate a hook. Fish the hanger down the drain and begin removing the gunk that is clogging your sink.

Make sure to remember that instead of pushing the hanger further down the drain, you should be focusing on removing the debris.

2. Baking Soda & Vinegar

If you want another DIY method to unclog your sink, look in your spice cabinet!

Pull out the baking soda, vinegar, and a mixing bowl. Mix together 1/3 cup of baking soda and 1/3 cup of vinegar. This mixture will begin to fizz almost immediately, and after it’s started to fizz pour it down your sink.

Let this concoction marinate in your drain for at least an hour. The fizzing action should break down the gunk stuck in your drain. After an hour, flush the drain with hot water and it should be as good as new!

3. Down to the Boiling Point

If you don’t have baking soda or vinegar, another easy DIY is to use boiling water. Boil a pot of water and flush it down the sink. If the water fills up the sink and doesn’t drain, allow the water to cool and remove it with a cup or ladle.

Repeat the process with another pot of boiling water until the clog easily drains.

4. For the Aspiring Handyman

If you’re wanting to be a bit more hands-on approach then break out your wrench. Open the cabinet under your sink and locate the U-shaped pipe (aka the Trap) and put a bucket under it.

Using your wrench, unscrew the bolts that hold the Trap in place. By unscrewing the Trap, water and debris that are trapped within will pour out into the bucket underneath. You might need to use an old toothbrush to wiggle the remaining debris out of the pipes, but this should solve your clog.

Once you’ve removed all debris, screw the trap back into place. If you have any leaks in the trap, this may also be a good time to assess them.

5. The Plumber Pipe

If this isn’t your first clogged drain, then you might have a plumber’s snake. If this isn’t your first clogged drain and you don’t have a snake, it might be time to invest in one.

These tools are specifically designed to remove excess debris from pipes. They can be found at your local hardware and are a good tool to have on hand. Fish the snake down the drain until you feel resistance. Move the snake up and down where you feel resistance and the debris should come loose.

6. Drain Detergents

Also found at your local hardware store should be a section of detergents specifically geared toward removing drain clogs.

Pick up one of these detergents from your hardware store and follow it’s directions. Allow the detergent to clear out the pipe for as long as instructions say. After you’ve used the necessary amount of detergent, flush hot water down the drain. It should flush the way it’s supposed to.

7. Call in the Caustic Soda

If you’ve tried detergents, snakes and boiling water to no avail, go back to your hardware store and ask for caustic soda (otherwise known as Sodium Hydroxide).

This is one of the more extreme ways to handle a clogged sink but it should get the job done. If you chose to go this route, make sure you have protective eyewear and rubber gloves to avoid chemical burns.

Pour 3/4 gallon of cold water into a mop bucket and add three cups of caustic soda into the mix. Stir the mix with a wooden spoon and it should fizz and heat up. Pour this down the drain and leave it for 30 minutes. After the mixture has sat for that long, pour boiling water to remove any excess caustic soda.
