Lubricate Rusty Screws with Soap
Rusty old screws? Just use soap! Rusty screws make your work harder and messier, and nobody wants to spend several minutes struggling with a rusty screw.
Get a bar of soap, wet it, and rub it a little until some bubbles start to form and it begins to soften. Rub the screw on the surface of the soap and use it immediately before it dries out and toughens. It should be way easier to work with now.
