I'm in the process of restoring some AR5's that admittedly didn't need a lot of cabinet work. Sanded lightly with 220 and used the following:
2 applications of Clear Satin Osmo Hard Wax Oil followed by a coat of Gilboy's Rose Gold Wax.
I've used this combination on a number of pieces of furniture and have never been disappointed. They are both easy to use and as non-toxic as you're going to find.
