While household detergents are a familiar sight when it comes to household cleaning, there’s been a recent trend growing online for promoting deep-cleaning methods as a quick fix for blocked drains. While this may seem like a good idea, heavy detergents can actually do your drains more harm than good.

Here are some of the problems detergents cause for drains and what you should do if your pipes are clogged.

Beware the online trend for using deep-cleaning detergents down drains

Have you seen some of the trending cleaning videos online? Social media platforms and home-cleaning blogs have popularised the idea of using deep-cleaning detergents down drains, including laundry detergents and dishwashing powder.

The results in these videos are often aesthetically pleasing, but using detergents in areas like bathroom sinks can actually lead to drain problems over time. While they may seem like a great ‘drain cleaning hack’ to get rid of grease, grime and debris, these methods can backfire. The reality is, most of the products used haven’t been designed to clear drain blockages or plumbing systems.

Does detergent clog up drain pipes?

Unfortunately, if you’re using heavy detergents in areas of the home connected to drains like sinks, it can lead to unwanted blockages. Detergent leaves a residue that accumulates in pipes over time. Unless diluted, a sticky and soapy layer will start to build up on your pipe interiors.

This residue will then trap other debris like hair, food crumbs, grease and other mineral deposits, leading to clogs and hair blockages. You may notice issues like slow drainage, nasty smells and overflowing sinks.

What problems can detergents cause down drains?

Overusing detergent down drains causes sticky residue build-ups rather than better results. The detergent can even interact with grease, fat and oil (especially in kitchen drains). Rather than dissolving these substances, the detergent may cause them to solidify with cold water to form a thick sludge, making stubborn blockages even harder to remove.

Most detergents also contain harsh chemicals that could cause problems to older or fragile plumbing systems, degrading pipes further. It may even lead to permanent damage and water leaks.

What should you do if your drains are blocked?

If you think your drains are blocked, avoid DIY cleaning methods seen on platforms like TikTok. Before taking remedial action, identifying the source of the blockage is key. CCTV drain surveyors have been in hot demand in recent times thanks to their efficient diagnostic methods.

During a CCTV drain survey, a small camera is fed through the drain system to provide visible footage of what’s causing blockages. Common culprits are fatbergs, debris and tree root ingress within the system. It’s the most accurate way to determine the next course of action and the drain fix required.
