For homeowners, there's nothing worse than trying to deal with the problem of dirty or mouldy tile grout in the bathroom.

The warm and humid environment of the bathroom - especially around the bath and shower area - makes it the ideal environment for mould to thrive.

And if you've been struggling with this issue, you're definitely not alone.

Dirty grout is one of the top frustrations for UK homeowners, according to a recent survey by Plumbworld, the bathroom experts.

However, there's a very simple trick that can bring your dirty grout back to life - and it only costs £1 to do.

If your bathroom grout looks dull and grimy, don’t spend a fortune on cleaners or professionals just yet. The £1 solution using everyday items is the latest viral cleaning hack, with millions praising its effectiveness on TikTok and online forums.

The secret is baking soda and a splash of white vinegar. This simple combination creates a fizzing action that deep-cleans grout, removing dirt, mould, and limescale with ease.

Baking soda acts as a mild abrasive, scrubbing away grime without damaging delicate surfaces, while vinegar’s natural acidity dissolves mineral deposits and kills bacteria lurking in the grout.

Together, they pack a powerful punch against the buildup that makes grout look old and discoloured.
 

All you need is bicarbonate of soda, white vinegar, an old toothbrush, and a damp cloth.

First, mix your paste by combining three parts baking soda with one part water. Using the toothbrush, spread the paste generously over the grout lines. Let it sit for 5–10 minutes.

Then, spray or carefully pour a small amount of vinegar onto the paste. It will fizz and bubble as it reacts with the baking soda.

Scrub the grout gently with the toothbrush, focusing on stained areas. Then, wipe clean with the damp cloth.

Many users report that this quick fix makes grout look “as good as new” in less than 15 minutes, leaving behind a gleaming bathroom that feels freshly renovated.

Not only is this method cost-effective, but it’s also eco-friendly, relying on natural ingredients rather than harsh chemicals.

The experts from Plumbworld experts commented: "Keeping your bathroom grout clean doesn’t just improve its appearance—it can also extend the lifespan of your tiles and prevent costly repairs caused by mould or water damage.

"Regularly wiping down your tiles after showers and using natural cleaners like this hack weekly can help you keep your bathroom looking fresh and save you hundreds on professional cleaning or tile replacement."
