+1 Jimmy, My razors out in rotation get wiped down with a Silicone Gun Cloth. When I'm done shaving, the razor sits out to dry while I get ready.
This step is important if it's sitting out in rotation or getting put up in a box, It must be completely dry. If you really want to be anal about it, You can use that canned air to blow out the pivot area. The same stuff you use for computers...A compressor will work too....Just hold on to that razor....!
Once dry, it's wiped down with the silicone cloth and sits out on a ceramic tile in my bathroom. I've never had any problems. Razors that are stored are wiped down with Camelia oil. I only use the Camelia oil for long term storage. To use it everyday, and wipe it off seems a waste to me. The gun cloth provides protection and is much more cost effective....
