I'll have to disagree WD40 is a good lubricant and preservative , it us a cleaner also. So the best of both worlds , I have used it for many things and on razors no ill effect , as a matter of fact I know of a couple guys who always use it and their guys who do this for a living. Not arguing , just in my experience it will not harm your razor and to tell you the truth I've never been harmed with it on my skin. Tc
