We all strive to maintain our homes in pristine condition, but appearances can be deceiving as a woman unexpectedly found out.

TikTok creator Nancy Birtwhistle discovered this the hard way with her “stinky sink” saga, leading her to warn her followers, suggesting they might be facing a similar grimy reality.

In a revealing clip, Nancy observed her sink appeared “quite clean”, noting its “white and bright” facade. However, removing the drain cover unveiled a shocking contrast.

A persistent odour led her to investigate further, as she pondered in the footage: “I wonder what’s lurking down there.”

Upon detaching the cover, Nancy’s disgusted “yuck” said it all, and armed with kitchen roll, the influencer tackled the revolting black sludge that emerged.

Scooping out the muck with a spoon, she couldn’t hide her revulsion: “This is gross”.

To eliminate the “thick gunk”, she carefully rinsed it away, placing a bucket beneath to prevent a “flood”.

Her go-to solution was her “basic magic” kitchen cleaner, prized for its “non-acidic” and eco-friendly properties.

She opted to cleanse everything in a bowl, allowing her to dispose of the waste outdoors, rather than risk clogging the sink again.

Nancy identified the culprit as “tea and coffee stained soap scum” mixed with “debris”, a combination that emits a particularly nasty stench.

The cleaning whizz shared her secret to a sparkling sink, using just a teaspoon of green bleach and a scrubber.

After replacing the drain cover, the transformation was remarkable, with a sink that was clean inside and out.

She chuckled at the end of her video, saying: “My sink was smelly, and now I know why,” and showcased a before and after snapshot of the results.
