5 DIY tips for how to unclog a bathroom sink

As well as HG drain and plug unblocker, there are a few DIY tips you can try to unclog your bathroom sink, however these aren’t always so effective.

1. Clothes hangerHow to unclog a sink

Using a wire clothes hanger, push this through the drain until you feel the blockage. Pull the wire up in a rotating motion to remove hair and soap residues. Once this is removed, throw it away rather than rinsing it down the drain, as this can cause it to block again.

2. Plunger

Fill the sink with a low layer of water. Place the plunger over the plughole with the plug on, then move the plunger up and down a few times without the plunger coming off the plughole. This can create suction to release the blockage.

3. Clean the trap

To unclog a sink without a plunger,put a tray or bucket under the trap. Then loosen it with a wrench. Clean any hair or build-up out of the trap and the drain. Put the trap back on by hand, run the tap slightly and check for leaks. If there are no leaks, then tighten the trap with the wrench.

4. Drain cleaning coil

Uncoil the drain cleaning coil and remove all the kinks and folds. Push the end of the coil down the drain. Once you can feel the blockage, rotate the coil then push and pull to loosen the blockage. Once the blockage is clear, you can pull the flexible cleaning coil carefully out of the drain.

5. DIY unblocker 

Pour a cup of baking soda down the drain and wait for five minutes. Then, pour a cup of vinegar down the drain. Leave this mixture to work for two hours. Next, boil some water and leave it to cool a little, then pour it down the drain to try and release the clogged sink.

If you tried any of these DIY solutions and they didn’t work, you should try a specially formulated product, like HG drain and plug unblocker. You can also see our guide on how to unblock a kitchen sink.
