I certainly wouldn't be sanding it, because it is easier to fix a tight one than a loose one. Bees wax is good, but I use it more for loose stems.
On mine, the least evasive way to fix is to take a #2 graphite pencil (Ticonderoga if you have it) and just color the whole end of the tenon with it giving it an even layer of graphite, and viola... it will work. You may have to do this every couple of dozen times you remove the stem though, but it is the least evasive means of fixing.
