This disgusting but effective laundry hack is meant to clean what washing machines can't.

They say everything old becomes new again, and right now, it’s old-school laundry hacks on TikTok.

(TikTok [tick tock] noun. A social media platform for young, hip people and celebs to post videos of themselves dancing, lip syncing and living life etc.)

Moving on.

With germs and hygiene at the front of our minds, there’s no better time for a laundry hack my nan would approve of to go viral.

Laundry stripping isn’t a new thing. The process, which involves soaking items for hours, is meant to remove built-up residue from soaps, washing liquids and powders, and fabric softener. It also draws out any minerals in your items from washing in hard water, and general grime, oils and gunk washing machines potentially won’t.

Only now, we’re spending a lot more time on social media looking for new hacks, tricks and tips to do around the house to pass the time in isolation. Case in point: 2-ingredient Nutella cakes and whipped milk in various flavours.

So, who do we have to thank for bringing back laundry stripping and cementing its place in the iso zeitgeist? TikTok user Lauren Elms (@mrslaurenelms).
