How should I clean a safety razor? Would a toothbrush, pipe cleaning brush and liquid dish detergent be enough? When should I use toothpaste or Scrubbing Bubbles(or an alternative like CIF Bathroom Ultrafast here in Romania)? What about vinegar for cleaning?
I've always used Scrubbing Bubbles. A) It eats soap scum 2) It disinfects III) It leaves the razor nice and shiny! The options you list will work, also.
