If you've ever struggled with a blocked drain in your bathroom or your kitchen, then you'll know how much of a pain it can be to get the water in your sink flowing properly again.
And while your first thought might be to splash out on expensive drain unblockers that usually cost at least £3 a bottle, there might actually be a cheaper solution to your problem, as one cleaning fan has claimed.
The woman - who is a fan of cleaning guru Mrs Hinch - has said she swears by a unique hack that involves using a popular brand of fizzy drinks to clear her drains, and insists it works every time.
In a post on Facebook, the woman revealed she pours a bottle of Coca-Cola down her drains to help clear them, and said the hack has always "worked" for her.
The woman responded to a post made by another woman in the Mrs Hinch Cleaning Tips group, who asked: "What is the best method or suggestion for cleaning out drains in bathroom sinks? I've used expensive stuff from a plumber, but within weeks [they're] back blocked. Any suggestions?"
And the cleaning fan replied: "Try a bottle of Coke. Worked for me."
The original poster hailed the woman's suggestion as a "good idea" and said she would try it out, but as of the time of writing, she has not reported back with any results.
The woman didn't specify what size bottle of Coca-Cola she uses, but a 1.75-litre bottle of Coke from Tesco is priced at £2.25, while 2-litre bottles of Diet Coke and Coke Zero are £1.99 each.
It's also unclear whether the hack needs the branded Coca-Cola or whether supermarket dupes would do the job just as well, but you could save yourself even more pennies by chucking a 2-litre bottle of Tesco Cola down the drain instead, as this is priced at just 70p.
Meanwhile, it was previously suggested by fans of Mrs Hinch that you can also use cola to banish stubborn brown limescale from your toilet.
And at the time, Coca-Cola released a statement urging fans to stick to traditional cleaning products.
They said: "Rumour-mongers have claimed that Coca‑Cola, due to its acidic nature, can be used to clean toilets and corroded car batteries, loosen rusted bolts and remove rust spots from car bumpers, get rid of grease from clothing and clean road haze from windshields.
"It's true there is a small amount of edible acid present in Coca‑Cola - just as there is in many foods and drinks. And it's quite possible that this edible acid could do the things the rumour-mongers claim. But we wouldn't recommend using it for any of these purposes. Just stick to regular cleaning products…"
