I have three step process for the cabinets:
3) Comment "Dear, does that one edge of the cabinet look a bit dull?"
Then go outside and relax, as the odor of whatever product she uses lowers the enjoyment of my Joe & Kah...
When we bought the coach, we did a good wood cleaning with Murphy's (Concentrate that we mixed our own strength in the bucket.) Let it dry for a day or two, then treated with a linseed Oil (Comes out of a 40 year old can that my Dad had bought.).
We've since done periodic cleanings with a product my wife has used on our home cabinet for years. (Sorry, can't recall the name, and she's not here to ask.)
Key message here was if it has been neglected, do a deep cleaning first.
