I been using this blade for like 4 shaves now and in the last 2 times dipped it in 97% alcohol to sanitize it and went to use it a 5th time and the van der hagen blade is like have a stain or rust on it and i want to know if you guys can recognize if it is rust and discontinue use or just a stain and safe if it feels right? If its because i dipped it in alcohol I honestly didn't know that would lead to this.. Would towel drying next time be a better solution?
