How to clean the drain of a double sink wash basin?

Jun 06, 2025

Hey there! As a supplier of Double Sink Wash Basins, I've seen my fair share of drain issues. A clogged drain in a double sink wash basin can be a real pain in the neck, but don't worry, I've got you covered. In this blog, I'll walk you through how to clean the drain of a double sink wash basin step by step.

Why Cleaning Your Drain is Important

First off, let's talk about why it's so important to keep your double sink wash basin drains clean. Over time, hair, soap scum, toothpaste residue, and other gunk can build up in the pipes. This not only causes slow drainage but can also lead to unpleasant odors. And if you let the problem go on for too long, you might end up with a full-blown clog, which can be a real hassle to fix.

What You'll Need

Before you start cleaning, gather the following tools and supplies:

  • Rubber gloves
  • A bucket
  • A plunger
  • A drain snake or auger
  • Baking soda
  • White vinegar
  • Hot water

Step 1: Remove Visible Debris

Start by taking a look at the drain openings. Use your gloved hands or a pair of tweezers to pull out any visible hair, dirt, or debris that you can see. This simple step can often remove a significant amount of the buildup and improve drainage.

Step 2: Use a Plunger

If the drain is still slow, it's time to bring out the plunger. Make sure there's enough water in the sink to cover the plunger cup. Place the plunger over the drain and press down firmly, then pull up quickly. Repeat this motion several times. The suction created by the plunger can often dislodge clogs and get the water flowing again. Do this for both sinks in the double sink wash basin.

Step 3: Try a Drain Snake

If the plunger doesn't do the trick, it's time to use a drain snake or auger. Insert the snake into the drain and turn the handle clockwise as you push it further down the pipe. You'll feel resistance when you hit the clog. Keep turning the handle to break up the clog and then pull the snake out, bringing the debris with it. This can be a bit messy, so make sure you have a bucket handy to catch any gunk that comes out.

Step 4: Use Baking Soda and Vinegar

Once you've removed as much of the clog as possible, it's time to give the pipes a good cleaning. Start by pouring about half a cup of baking soda down the drain. Follow it with about a cup of white vinegar. The mixture will fizz and bubble, which helps to break down any remaining grease and grime. Let it sit for about 15 - 20 minutes.

Step 5: Flush with Hot Water

After the baking soda and vinegar have had time to work their magic, boil a kettle of hot water. Slowly pour the hot water down the drain to flush out the loosened debris and the baking soda - vinegar mixture. This will help to clean the pipes and get rid of any lingering odors.

Step 6: Repeat for the Other Sink

Don't forget to go through the same process for the other sink in the double sink wash basin. Even if one sink seems to be draining fine, it's a good idea to clean both to prevent future problems.
