My sister bought me a fantastic Joseph Joseph adjustable rolling pin for my birthday, hooray! I used it last night for the first time, and when I checked the box for cleaning instructions, it said to hand wash only and "oil the wood frequently." I've never had a rolling pin that required this before and am kind of at a loss. Google has informed me that one way to do this is a small amount of canola oil on a paper towel, while others swear you have to only use oil made for the express purpose of oiling wood that comes into contact with food (and also that you should never use soap on the wood; oops). Help?
