On the other hand, commercial grade bathroom cleaners are caustic as hell and will do exactly this type of damage to carbon steel in a heartbeat. I will be happy to clean it up for you and rehone it free of charge if you would like. At any rate, I don't believe that there is anything intrinsically wrong or defective with your razor and wish you the best of luck in getting it sorted.
