Swipe some lemon oil (nice name for mineral oil) over them. David
suggested felt glides, and that's a good idea, too. If the floor is
swept very frequently, nylon glides also work well.


I've never heard this advice and am interested to know more. I can see
how the oil would help conceal scratches, but wouldn't it make the
floor slippery, trap dirt, and wear off eventually? Also, wouldn't
the oil interfere with an eventual top coat of poly?
