With 12 razors, this is what I'd do to avoid any rust issues. Do steps 1 and 2. Let the razor sit in a dry place for a day, then oil it with ballistol. Takes a bit of adjustment, but it becomes a routine. Once you run out of it, you can just buy mineral oil, available for as low as 1-2EUR in any pharmacy. It will protect your blades from rust and it's dirt-cheap. It's also very safe, since baby oil is just scented mineral oil.
