Got my first resto lot today, and looking at it, it's going to need some work. Two of the razors in the lot are just stained, but that's not the topic at hand. Two of the razors are rusted, and one is pretty darn bad (but the blade is so hopelessly broken I don't care. I'm really thinking of trying electrolytic rust removal, and am going to use the junker as a test. The other razor is a C-Mon blackie, and I have every intention of doing the same electrolytic treatment to it as I do to the junker, but its got to survive. I was planning on setting up something like the following.
Plastic or glass container
A nail as an anode
A 1000ma (1 amp) 12V DC power supply, maybe only a half amp one. This should keep the current low enough that I don't create a ton of heat and wreck the blade.
Water and baking soda (salt water is apparently not so great).
Put all of this on a GFI protected outlet (just in case), and have it going outside.
My one concern is that when the solution is fresh, the current between the rusting blade and the anode could be greater than an amp, resulting in a crispy fried power brick. Originally I was thinking of a resistor, but apparently the resistance between the electrode on the razor and the anode will change the more rust is in the water. I guess that means the current will start rapid and slowly decrease as more rust is removed, or perhaps I should consider using a variable resistor.
I'm also aware of the fact that this will only remove rust and will not remove pitting. I'll deal with the pitting another time, maybe a few months down the road . Meanwhile I should be left with a honable (albeit heavily pitted) blade. As soon as the blade leaves the soda bath it's going to take a Ballistol bath so it won't rust again. Has anybody else here ever done this? Any tips?
