well I dont wax mine more than a couple of times a year, but the wood can get a bit dry. The warwick wax is rather hard and dosnt always soak in as well as it could especially on wood that is a bit dry. So I have switched to using a softer wax. just avoid any of the silicon based polishes. Bees-wax based furniture polish is just fine (ex spouse makes her own as a by product of her bee keeping hobby I find this works a treat).

Charic it tends to work the other way round kids borrow your basses, dont wipe the strings down after sweaty practice, and develop chops that puts parents efforts in the shade....It is still worth it though.
