So I am a bit of a hypochondriac and have had a strop strung of the ***-wipe dispenser. It has been sitting there idle for about 3 years. I am converting back to straight shave when I am home from the norm DE shave away from home which is five days a week I am not sleeping at home. What is the best way to sterilize the strop so that I can set it back up to use for straight shaves?
