To start with you should at least use tung oil. 100% pure tung oil is what I use amongst other wood products. In general several applications of 100% pure tung oil could suffice. Pure Tung Oil is water and alkali resistant offering a protective barrier.
There's other products and finishes available for wood. Others will hopefully chip in.
