White socks are a wardrobe staple, but keeping them pristine can be a challenge due to their susceptibility to dirt, stains, and yellowing. A cleaning expert recommends using lemon juice as a natural bleach to whiten socks without the harshness of bleach. Simply soak your stained socks in a bowl of warm water infused with lemon juice for 2-3 hours, then wash them as usual in the washing machine. Lemon juice not only brightens white socks but also acts as a natural fabric softener due to its citric acid content.
