This morning, while cleaning my Mühle Rocca R96, I found a tiny rust spot. Fortunately I could easily wipe it off using some vinegar and a paper cloth. I blame the Rapira blades, and my neglect to remove the blade after each shave ... Anyway, would it be an idea to apply a coat of car wax (turtle wax) on the razor head? I can't see a reason for not doing it ... if anything, it would make the head glide even more easily Or am I overlooking something? Thanks! BTW, I took the opportunity to rub the whole razor head with vinegar ... every trace of soap scum is gone now, so this would be a great moment to apply a protective coat.
