Sometimes it feels like you can only wear a white piece of clothing once, before it gets stained and its colour dulls after just one spin in the washing machine. No matter how hard you try, those whites always end up looking grey.
However, one TikTok trend doing the rounds on social media promises to have your whites looking bright, and the best bit is, it'll only set you back a few pence.
The hack was shared by one user, @burcibaci, who revealed the one simple and cheap item you need to add to your wash to ensure those whites stay white - washing up liquid.
