March 28, 2024

Given how much dirt, bacteria, and grime they're exposed to on a daily basis, it's no surprise that sink drains can start emitting unpleasant odours over time. And not only can a smelly sink drain make your kitchen or bathroom feel less clean, but it can also be a sign of underlying plumbing issues. 

Fortunately, there are straightforward and effective ways to tackle this issue head-on. In this guide, we'll explore several methods on how to clean a smelly sink drain, ensuring your space remains fresh and welcoming; from natural remedies to preventive maintenance, we've got you covered. So, if you're troubled by a less-than-pleasant odour emanating from your sink, read on for practical advice and solutions.

Identifying the Culprits Behind Sink Odours

The first step in addressing a smelly sink drain is understanding what causes these odours. Often, the culprits include food particles, grease, and soap scum that accumulate over time, creating an ideal environment for bacteria to thrive. If you've noticed a persistent unpleasant smell, it might also indicate a partial blockage that needs attention. 

Essential Tools and Materials

Before diving into the cleaning process, ensure you have the necessary tools and materials on hand. These typically include:

  • Baking soda
  • White vinegar
  • Boiling water
  • A plunger
  • A DIY cleaning solution (detailed below)
  • Protective gloves

Make sure you’ve got these tools on hand before you get started - it’s always best to have everything you need in one place, and you don’t want to have to stop what you’re doing to go looking for something you’ve forgotten.

Method 1: Baking Soda and Vinegar

Next up, one of the most popular and effective natural cleaners involves using baking soda and vinegar. Here's how to do it:

  • Pour half a cup of baking soda (also known as baking powder) directly into the drain.
  • Follow with a cup of white vinegar.
  • Allow the mixture to fizz and work its magic for 10 minutes.
  • Rinse with boiling water to clear away the residue and odours.

This method is great for neutralising odours and dislodging minor blockages, but might not work well on more stubborn clogs, which may require something like an enzyme cleaner or even professional intervention. 

Method 2: Hot Water Flush

Next up, a hot water flush. Sometimes, a simple hot water flush can do wonders for eliminating sink odours - and the good news, it’s pretty much completely free! Simply boil a kettle of water and slowly pour it down the drain. The heat helps dissolve fats and greases, clearing away potential odour sources, and if you repeat this process weekly, you can also integrate it into your home cleaning routine as a preventive measure.

Method 3: DIY Cleaning Solution

For a more potent cleaning solution, you can also take the DIY route. To do this, you’ll need to mix together:

  • 1 cup of baking soda
  • 1 cup of salt
  • 1/4 cup of cream of tartar

Pour half of this mixture down the drain, followed by two cups of boiling water. Wait a few minutes, then flush with cold water. This concoction is particularly effective for tougher grime and blockages, but again, this won’t work on your most stubborn clogs.

Method 4: Plunging Away Blockages

If the smell persists, you might be dealing with a blockage, so using a plunger can help clear away whatever is stuck in the pipes. Make sure to cover the overflow vent and create a tight seal around the plunger for the best results.

Preventive Measures for a Fresh Sink

Prevention is key to maintaining a fresh-smelling sink; regularly clean your drain using the methods above and avoid pouring oils, fats, and large food particles down the sink. Additionally, consider using a drain strainer to catch debris before it causes problems.

Should odours persist despite your best efforts, it may be time to consider professional help. Persistent smells could indicate more serious plumbing issues.
