This is pretty much what I do whenever I get a new Vibram (or a used one that I haven't held before). I use just plain ol' dish soap and a mildly abrasive sponge and scrub the whole disc then rinse it off and dry.
The person that first advised me to do this said something about the discs some how ending up with a slippery residue when finishing the manufacturing process that doesn't always get removed. I am not sure if he's right, but I don't see a huge reason that it couldn't be without Steven telling us otherwise.
