First thing you should do though is to buy two cans of motorspray. Just spray the entire first bottle before you take it apart. Then spray off the excess residue with an air compressor, and then take it apart. Use the other can of motor spray as you would usually use it to clean out diffs, bearings and other stuff.
I'm just like fraz when it comes to paranoia of unclean race cars, and I would say that Corvette's suggested tools are what I usually use (though I do have some other wacky stuff
) and you should also check to see the condition of the motors' innards and the electronics. Cycle the battery pack a couple times if it is rechargable or replace them if it is unsalvagable or if you use alkalines.
