black speck rust?

What is this blackish rust I see in old Ebay razors and can I get rid of it by hadn sanding?

You talking about the tarnish?

Yes, it can be sanded away, but there might be some pitting underneath which may take a bit more work to remove.

I guess that's what it is. It looks like mold? but I am using a finer sanding paper and having a hard time getting it off.

It is basically stabilized rust. You can remove it but you might have to drop down below 220 grit to really remove all. Once the black part is removed, you may find that it etched the blade somehow and you still need to sand some more.

Sometimes yes, sometimes no.

Yes its the devils spit stuff that was described in that thread. Hmmm this is going to be tricky without any tools to get it cleaned up.

That kind of rust is like a cancer. It has permeated the pores of the metal and is so deep that even if polished out it will come back. The only way to stop it is treat it with a rust converter to stop the process and then polish it out. You have to be careful with the rust converter. You need to treat the whole blade prior to polishing the razor. If you leave the rust converter on too long it will turn your razor totally black and it will be harder to polish. This is showing that the metal of the entire blade has this process working and it needs to be stopped on the entire blade. Once the rust converter has covered the blade for about five minutes you wash it off with soap and water to neutralize the converter and then dry and polish. When I say polish I don't mean with Flitz or Brasso I mean it will need to be sanded with 600 grit sandpaper at a minimum. Having this done with fine abrasives on a wheel would be much better. It will be a pain but when you are finished you will once again have a great razor.

I point out how it turns the metal black to emphasize how the rust converter works because it will not do much at all on new steel - it actually needs the rust to work. It burns the rust into a polymer. The rust converter can be picked up in the automotive section of Wal Mart. I paint it on with QTips.

You should be able to get it in your closest DIY store.
