proon,
During the shave I rinse in warm water - about the same temperature as the lather when first whipped up. After the shave I do what many of those who commented here do and that's rinse with the hottest water I can, then wipe the blade dry, and then fold it up with the edge covered by the handle but not closed tight so air can circulate a bit around the blade just in case there is a bit of moisture I missed. The hot metal should dry itself and moisture won't get trapped between the blade and scales with the blade "ajar".
While I'm not the most experienced shaver here, I've had no issues with corrosion on any razor in rotation for over a year. And I store them in my bathroom - not oiled, only as dried.
Good shaving
