Carol, I haven't used anything in my new RV, but in my 1986 Holiday Rambler TT we used to have, I used Lemon Oil on the cabinets. I found it worked really good, considering the age of the rv, the fact that we live in humid La, we both smoked at that time, etc. so I figure the wood absorbed a lot of "stuff" and using the Lemon Oil worked really good, made them purdy and smelled nice too!
Another thing you might consider using is Murphy Oil Soap, after we flooded, I used it to clean the funk off of the few things I refused to part with, like my Momma's sewing machine cabinet. I'm sure others will give you more ideas also.
