I bought an old oak desk that had spent part of its life being used in a car repair garage It was in good nick but very dull and dirty in parts.
I used this stuff on it

and it brought back a beautiful glow to the wood. The patina of age is still there but it has a soft glow and looks well cared for. The green top is for light woods and the red top is for dark. I didn't want to change the colour of the wood at all so even though the oak might be described as a dark wood, I used green top on it. I used cheapo microfibre cloths to apply it and the same to polish it, the kind that look like towelling, not the finer kind.
