Thread: discoloured blade

I'm new to the world of restoration so would appreciate a little help. I understand pitting and what it looks like and also understand that you should try and remove as much as possible without compromising the blade.
On the blade I'm working on which is a cheap vintage off eBay to practice on so any mistakes don't really matter as it's one to learn on and if it all works fine.
Now the question, what are the black marks on the blade and do I have to sand these out completely with a low grit before moving up the grit scale. I understand the progression to get the desired finish but you can still see these black marks, which look like a water drop has splattered on the blade for want of a better description.
Once I've got the answer to this question another one has popped into my head, how do you know when to move to the next grit?
Thanks again for your time, it's appreciated.
Apologises if I've missed this somewhere on here but there are so many threads to look through.

Pictures speak a thousand words. The black marks could be zombie blood, plain old rust, or some sort of ink/paint. If you don't want it on there, sand it off. Just remember once gone, it's gone (etchings, etc.).

You move up to the next grit when all of the scratch marks of the previous grit are gone. I learned the hard way, 400 grit is about the coarsest sandpaper I use now.

bought dubl duck not expensive, light rust on blade I used just a whal oil bath followed by dail soap then maas polish applied with cork
the rust is gone but beneath the rust the blade surface is lightly ridged and I know by feeling it it is slight pitting
question is do I find a rubbing compound at auto zone first and thin sand paper or first sand paper the then use rubbing compound then sand paper?

I bet you'd find this thread really interesting, and really helpful.

Black spots can also be what we refer to as devil's spit. If it's an expendable razor try sanding them out & then see what's left of the razor.
