I use a 1:1:1 Linseed Oil, Turps, Beeswax mixture to periodically recondition interior furniture. It brings out color and sets up to a dull sheen but it doesn't go deep and remains soft. Like the man said, very fragile.
OTOH, 1:1 Oil and Turps is lovingly referred to as "boat juice" and I slather it on every part after gluing but before nailing and at the beginning and end of every season.
