Our house was built in the late 40's and has wood floors all upstairs. We have thought about sanding and varnishing, but the regular sanders are either too heavy or bulky to go up the small stairs. I have spot treated areas with pledge to clean certain spots. The floor is worn and needs help. We want to move our bedroom upstairs in a few days, so I need help FAST!!! Thanks for your advice. --- Heather M. Phillips
