I supppose hot water would be more conducive to immediate oxidation. It might also cause some expansion warping. The problem is that when you rinse the blade between strokes, the hot water softens the shaving cream and helps it to wash away. Cold water would have the opposite effect...the shaving cream (and shaved hairs) would stick and maybe clog up the blade. I guess I'll try cold today and see what happens.
