Tom Kraeutler asks,
I'm restoring the wooden floors throughout my house. There used to be carpet but we removed it, and I don't know what to do the stains it left behind on the wood. Most of the floor looks great, but one large stain in particular seems to go quite deep, so I cant just sand it out. Is there something I can treat the wood with? Or maybe a dark stain will make the stain less noticeable? Any suggestions are welcome.
