One person had taken to the Mrs Hinch Cleaning Tips group on Facebook to ask for advice, writing: "I'm going to try bleach on these stubbornly stained white t-shirts and socks.

"They all have a little different coloured logo on them though.

"Can I still use it?"

People quickly took to the comments section to offer their own suggestions, with many recommending Napisan.

"I would avoid using bleach," one wrote.

"I used it on school shirts and it turned them yellow I had to bin them.

"I would try Napisan."

"I would recommend Napisan," another commented.

"Bleach used to be my go-to until it turned my socks and a top yellow.

"Napisan is amazing, doesn’t affect other colours and works so much better than bleach."

Manufacturers recommend adding two tablespoons of Napisan alongside your regular detergent in the wash for the best results.

You can even wash at 30 degrees with Napisan.

It works to remove stains by releasing active oxygen, which also kills germs - which is why so many parents use it to get rid of marks on their kids' clothes.

For more intense stains, mix 60g of Napisan with four litres of water and soak the stained items in there for six hours.

Then wash as normal.

As you can get an 800g box of Napisan for just £4.50 in all good supermarkets, the stain-removing hack works out at around 16p for use
