I don't have enough razors to worry about stuff like cell rot and all my razors are in my rotation.

I dry, strop and leave my razors out on the bedroom for the rest of the day after use.
My 16 razors are kept in a couple of drawers in my jewellery box with some quite large silica packs that I bought about a hundred of from Amazon.

I don't know if they would help avoid cell rot but I'm sure they help keep my razors dry and rust free.
