Moved into my 1980s fixer-upper in Cleveland 3 months ago and those hallway floorboards squeaked like crazy every time I walked to the bathroom at night. A neighbor told me to sprinkle baby powder into the gaps between the boards, then work it in with a soft brush. I tried it on a 10 foot stretch last weekend and now it's dead silent. Has anyone else found a random household item that fixed something annoying around the house?
