I keep my straight clean and dry by drying it on a rough tea towel (bearing in mind that at the micro level the razor’s face contains thousands of lunar craters) then swabbing it both sides, and the edge and back, with a tissue dipped in methylated spirits (70 per cent alcohol). Swabbing sterilises the blade, ensuring that you don't get those occasional infective face-bumps that can occur after wet shaving. It also ensures that the blade is well and truly dry before you pack it away.
