How often to you clean your razor. I only have one. A Merkur HD. when I do clean it, a put it in a shallow container, zap it with scrubbing bubbles, and let it sit. I do this two or three times till the soap scum is gone, and it shines. I have heard this is the best way to clean a razor, but that it can damage the plating. Is that true? and if so, how often can i safely do it with out harming my razor?
