Kinnaird Bore Oil is the best I've used in 47 years of piping. I live in an arid area with low humidity and hot summer days. I maintain 3 sets of blackwood pipes and practice chanters, so I go through a lot of oil with two treatments each per year. The Kinnaird product smells good and is readily absorbed into the wood. Other oils get rancid and smell like petroleum products, but this one doesn't. I highly recommend it.
