cold storage
Wash and wax the cars
Recent oil change
check radiator and windshield washer fluids
check transmission fluid, top off if needed
check tire pressure, pump up if needed
Fill the gas tank with no-alcohol fuel, add a can of Seafoam and drive it for about 20 miles.
Get some chunk mouse poison and paper plated, I use Tomcat because I can get it at HD. One chunk on a paper plate under each car, one under the hood, one inside on the passenger foot-well
Disconnect the negative battery cable (both to save the battery and in case there should ever be an electrical short).
Put the car cover on.
Then every month or so: pull the car cover, hook up the battery and remove the poison. Run the car to get it to operating temp. If you have room, move the car forward and back at least a few feet. When done, put back the poison, unhook the battery and put the car cover back on.
That pretty much covers my routine (can't think of anything else) and it's worked ok for me for years now on multiple cars. Hope that helps.
