clean out an old blade with deep black stains is it possible?

[Oustoura]

Hi SRP,

Since a while I'm thinking a way to clean some old blades with deep rust marks. I tried with 300 grit of sandpaper but not satisfied with the result.

Actually I live in an Small apartment with no balcony, neither garage. So I don't want to buy a wet grinder machine. I don't have any place to keep it. So I was wondering if there a way to grind a blade by using only dremel with the head stuff which I don't know yet ( not these stone heads or to abrasive sandpaper stuffs, I already tried them and they destroy the blade and can not go further with less abrasive ones because they don't exist for Dremel). Or any possibility to put sand papers on Dremel to grind a blade to give it a new look?

Anyone tried this kind of thing before? I'm thinking on that and as an amateur, I'd like to find a way because with Dremel I know I can go slowly and decrease the work faults.

I'll appreciate any idea

I'm not an expert restorer, but ......... I've used dremels and they don't go slow. Aside from that, if any of these black stains are at the bevel you should hone the razors until you are past the black corrosion and on to good steel. Saying that if it is too deep at the bevel you may be wasting your time. With deep rust the edge will start to fall apart, looking like Swiss cheese.

It would be really best if you could post photos of what you have.

Steel wool works to take off a lot of gunk. It requires great amounts of elbow grease and as the end nears a little mothers works well too. It may take a little more elbow grease than you have patience for.

Pictures of how bad the blades are would help provide a good approach. I've tried steel wool, and have never been satisfied with the results. Get an assortment pack of sand paper. Really, really bad blades I start at 80 grit.

I wonder if you got the cotton buffing wheels and charged them with a high grit paste, like the black, how that would work. Rather than putting them on a strop, the buffing wheel might be the balance you are seeking.

Pitting has to be sanded by hand or with a drum and Dremel, Use a Variable speed, at the slowest speed and a flex shaft for best control and comfort.

Or Greaseless, which is messy and takes a bit of an investment.

Hand sanding is the other alternative, will take time but can be done. Sometimes, you just have to live with some pitting.
