Mugs which are used for hot drinks such as tea and coffee can become incredibly stained.

It is the staining agents known as tannins within the beverages which produce this stain on the cup.

Whilst stained mugs are perfectly fine to drink from, they can be unsightly, especially if offered to a guest.

Posting on the Mrs Hinch Cleaning Tips Facebook page, Tia Macaulay wrote: “Does anyone know how to get rid of tea stains in a mug? I have a lovely Cath Kidston mug but I can’t budge the stains.

“I also can’t put it in the dishwasher. I’ve tried soaking it in boiling water with washing-up liquid and nothing.”

The post attracted hundreds of comments with recommended hacks, including denture tablets.

Sonia Alden wrote: “I use denture tablets and boiling water. Let it sit for a bit and then wash as normal. It is much safer than bleach and does the job perfectly.

“I prefer to buy the minty denture tablets as then I can smell if the tablet has lingered a bit and I need to wash the cup a bit more."

Harriet Young commented: “My nan recommended using denture tablets as she uses them for her teeth but also around the house for literally everything. They work so well and are just so cheap.”

Joanne Westwood also recommended using denture tablets dissolved in hot water. The Mrs Hinch fan added: “Old trick I learned from my Nan many years ago. Cleans teaspoons up a treat too.”

When combined with hot water, the two react to create a fizz which helps to banish the stains.

Soak the mug for around 10 minutes and repeat if necessary, although one time is usually sufficient.

Sainsbury’s currently sells 30 cleansing tablets for just 90p, meaning to clean one mug, it would cost less than 3p.

Boots, Amazon, Asda and Morrisons also sell denture tablets at varying prices. Others recommended using table salt to help scrub the brown stains around the mug.

Linda Thomson said: “Salt with a little bit of water will work. Rub with your fingers around the stain, it’s like exfoliating the inside.”

If you’re looking for a specialist product, Astonish has a product called Clean and Revive which helps to bring mugs and crockery back to life.

It was recommended by Allyson Pearson who said the product was “fantastic” and brought her mugs back to life.
