WD-40 isn’t just for squeaky hinges—it’s a surprisingly versatile household tool. Originally made to repel moisture and prevent rust, it can also remove stickers and gum, unstick zippers, clean garden tools, shine stainless steel, protect outdoor furniture, erase crayon from walls, silence creaks, and even clean toilets. Just spray responsibly, and this little can could save you time, effort, and money around the house.
