16 Forgotten Laundry Tricks Grandma Swore By (Some Are Wrong)

Monday was wash day. Soda crystals, a washboard, and hands red to the elbows. Grandma's generation had a laundry trick for everything. Soda for the whites. Salt for the colours. Cold water for blood. Milk for ink. Some of those tricks still beat anything on the supermarket shelf. Others quietly ruined clothes for decades. So we checked sixteen of Grandma Wil's laundry tricks against the people who actually know: university extension services, consumer testers, scientists and the makers themselves. Every trick gets one of three verdicts. Works. Half true. Or myth. And for three of them, Wil had to admit she'd been wrong for sixty years. And number sixteen, the blue one, sounds like it can't possibly work.

It can release dangerous gas. Test any stain remedy on a hidden seam first. Grandma Wil is a fictional, AI-generated character.
