here's my two bobs' worth on storing razors, having tried silica beads, oils,etc.
throw some mothballs into your razors' storage container. i like cigar boxes, but that's a personal thing. the camphor fumes coat everything in the box with an oil coating and stop corrosion. when the razor is removed from the box, the volatile camphor vaporizes in a few seconds and voila - razor ready for shaving with no prep. i've not had camphor affect any of the non-metallic parts of the razors, and i've got razors with plastic, mother-of-pearl, wood, and bone bits.
this also works wonders in a toolbox, providing the seal is fairly airtight.
