I apply mineral oil after each shave, wiping it off before each shave with a kleenex. I even fold one to apply oil to the tang where it passes between the scales and also to wipe off from that same place. I also clean out the oil from the scales where the blade touches them near the spine. Nearly 2 years in, 8 razors, 1 bottle of mineral oil, no rust, no strop damage (at least not from the mineral oil--strop damage from stropping--well, that's another thing . . .).
