Yah, don't over think this. You don't wash your kitchen utensils "several times" between use.
My Spyderco Manix LW in S110V cannot be disassembled. When it get's really dirty, I just swish it around in a bucket of hot water and dish soap for a few minutes, shake it dry, use a hair blow dryer for a few minutes, then add a couple of drops of mineral oil on the pivot, work it in, then wipe down the blade with any excess. Done.
You can get pharmacy grade, food safe Mineral Oil at any grocery/drug store's 'laxative' section for $2/pint.
