Mineral Oil

This is great stuff.  If you have a wooden cutting board, you use a little of it once a month to keep your wood moisturized and smooth.  However, you can use it on other things to.  For instance, I have some pampered chef bamboo utensils.  After a few months, the nice satiny finish begins to wear down leaving it looking dry.  So, give all of your bamboo a nice bubbly spa bath (in your sink), and towel it dry.  After you towel it dry, allow it to air dry for a while too just to make sure.  Then, rub it with a very thing layer of mineral oil.  I used a small piece of parchment to do this since it doesn't absorb the oil.  After you rub down each piece, go back to the first tool you rubbed down, and buff for a few seconds with a clean towel to remove any excess oil.  Then store as usual.  If the suface is rough at all, sand it a couple of minutes first with a very fine grain sandpaper.

If this sounds time consuming or boring, then just do in when your sitting in front of the TV not moving anyway.  You'll never notice the time was spent doing something constructive.
