Well if youve ever tried to clean an antique of live rust this will be repetitve, but just in case here is exactly what you do. I normally take the 0000 steel wool and scrub the rust gently. Now if its stubborn (like most rust is) I then soak the blade in WD-40 to loosen and soften the live rust and let sit for a little while. Then I go back with the steel wool and keep repeating till Im satisfied. To get into tiny cracks and pits I use a dental pick and a brass wire brush. Now the reasoning behind the 0000 steel wool is that at this fine a grade (do not use anything less fine) the wool will only remoce the soft rost but break off once it hits the the actual harder steel. Now some people will not even use 0000 steel wool but will only use brass wool, deer antlers, or copper instruments. Again the basic logic states that if it is softer than steel it wont scratch. Now realistically if I was working on an antique whos patina I was trying to keep intact this would be a long drawn out process in which I would have to carefully do the blade in sections with plenty of light and a magnifying glass to make sure that I am only working on live rust and not removing patina. However since this is not an antique it can go fairly quick. The brasso is for after the rust is gone just to try and remove any scratches that may have been incurred. If the blade is already extremely scratched then I would advise going through the various grits of paper as the only way to get those out. But if you blade was scratch free to begin with then ideally the finish should be relatively intact after the rust is removed and only slight touch ups would be needed with the brasso. Brasso is a really fine polisher meant for well brass. It will take out scratches but since its so fine itll take a long time and well if the scratch is deep a really really really reall long time. I used brasso because I had it lying around. Simi-chrome or flitz would probably work better as since theyre more meant for this than brasso. However Brasso will work if youre patient. Just dont expect it to be easy or fast. Geez depending on how bad the rust was (aka if there was any pitting or deep staining) you could probably skip the brasso route. I did it just because I wanted to polish it up a little. I also prefer 0000 steel wool as a silver and brass cleaner. I actually only use brasso now for polishing up blades to that mirror shine when I have nothing else around. Oh well I guess the old saying holds true there many ways to skin a cat.
