Thanks.  I'm not really worried about floors.  They are at least 10 yrs old. It's the filth I can't stand. Looks unclean and unhealthy.  I know that I will have to use a very,very light coat of polish on them and clean with clean, warm water after that.  I have to make sure all spills are cleaned up immediatly.  Ha, tell that to my 3 grandchildre (7, 6, 4). As soon as I get it done, I'll let you know.  Thanks so ever much.
