Hello. How do I remove limescale off a safety razor? After every shave I wipe down the razor with a microfiber cloth. After every blade change(about once every 4 shaves), I clean the razor with a toothbrush, water and dish soap. I used CIF Bathroom Ultrafast, but I believe it may have damaged my first safety razor(Edwin Jagger 89DE). Now I have a Wilkinson Sword Classic Safety Razor. No matter how dry my razor it, after some time limescale appears. Maybe it's because I have hard water.
