Found this pokin around, has some good insight into finishes and how to treat them. Read all the way through, refinishing info is at the end.
NO PEEKING!

Good Morning mrm,
That was a great article and since I do a large quantity of furniture restoration I will have something now for people to read on the care of
their furniture after I have refinished it as well as to help them care for the furniture they already have. I have told some folks and actually had them get upset when I would tell them that all the piece needs is a good cleaning.

Thank you for posting this article.

Respectfully,
