Whether it's in your kitchen or your bathroom, there's no reason to put up with drain smells. Sometimes a few simple methods and a willingness to be consistent are enough to get rid of smelly drains forever.

Domestos Thick Bleach is a strong and powerful cleaner that eradicates bacteria in drains, toilets, and on surfaces. Use it to tackle pongy plugholes in your home.

What Causes Smelly Drains?

Before you can tackle the problem, you need to know what caused it. Here are the most common culprits:

  • Drains that are clogged up with hair, food, and other debris are the perfect breeding ground for odour-causing bacteria.

  • Sewer smells can rise up through the drains if there is a bigger blockage or problem underground.

  • If your pipes are completely blocked then water can start to pool at the bottom and this will smell after a while.

  • A build-up of mould or mildew in the pipes can also release bad odours.
