Many people prefer wearing airy white socks during the hot summer weather, but the only downside is that they can be almost impossible to keep clean. 

White socks are more likely to show stains than other coloured socks which means they are also more likely to become discoloured, dingy and dim over time.

However, Henry Lee, a laundry expert from Monfoot Socks, has shared there is a “secret weapon” to restore white socks and get rid of stains that is likely already in your kitchen cupboard. 

Henry said: “Lemon juice, with its natural bleaching properties, can work wonders in whitening your socks when used in boiling. 

“It's a simple, natural, and cost-effective method that you'll find surprisingly effective.”

How does lemon juice help wash white socks

It may seem odd, but the acid in lemon juice can cut down the dirt that has become baked into the fabric that has turned socks a horrible yellow or grey colour. 

Many people make the mistake of using bleach to try and whiten fabric, but it is far too harsh to use on fabric regularly and can cause socks to develop a yellow tinge instead of restoring them. 

Citric acid, which is found in oranges, limes and lemons, is a natural bleaching agent that is gentle on fabric, breaks down stains and also helps fabric appear brighter. 

How to restore white socks and remove stains using lemon juice 

To begin, place the white socks in a basin and fill it halfway with warm water, which will help loosen up any dirt or stains to make the lemon juice method more effective. 

Next, fill a kettle with water, fill it with a generous amount of lemon juice and bring it to a boil

Pour over the boiled lemon water into the basin and allow the soaks to soak for at least two hours or longer. 

Henry said: “The heat combined with lemon juice works to lift the stains and restore the brightness of your socks.” 

Once the time is up, take the socks out of the basin and place them in the washing machine on a normal wash. Before going into the washing machine you may notice they are already white and the stains reduced. 

Hang the socks outside to dry on a sunny day as sunlight enhances the effects of lemon juice in a process called photobleaching.

When socks soaked in lemon juice are exposed to sunlight, the ultraviolet rays activate the citric acid to help break down stains in the fabric. 

Henry said: “The sun's natural bleaching effect will help enhance the whiteness of your socks.” 

Once the socks are dried they should be completely white and stain-free once again. Henry added: “You'll be amazed at the transformation: your socks radiate a whiteness rivalling snowy day.”
