Baby Powder on Hardwood Floors?

Q: I have a squeak in the old wood floors in one of my bedrooms. I read that I can put baby powder in the floor to fix the squeak. Does that work? 

Getting talcum powder or graphite into the small gaps around squeaking boards may be a short-term fix, although any time you put something that isn’t recommended on the floor you run a risk of contaminating the floor for future recoats. The best option for squeaks is to solve the problem, which, for squeaking floors, is a loose board. There are many ways and products to address that, from screwing down the board from below to using epoxy repair kits.
