    I inhereted my dads knife collection when I moved out on my own. I also left them right where I found them, in the bottom of the gun cabinet. So for some reason I was in the drawer and started looking at all the knifes. They are all rusted. To much humidity in the drawer. So what can I use to get the rust off without causing anymore damage to the blades than there already is?
    Thanks

    Both. Some have very light rust and some have thick. Sorry the pic quality isn't real good. I want to clean them up and build a display case for them. Or somehow hang them up to show off.

    On rusty machine surfaces, a bit of oil and a 3M scotchbrite pad (scouring pad) will get most of it off, and not damage the surface finish, but I have not tried it on a rusty knife blade. It may be a place to start....Good luck with these, Kirk

    0000 steel wool and WD 40. Scotchbrite pads will scratch the surface.

    Naval Jelly and other phosphoric acid rust removers will etch the metal.
    Use 0000 steel wool and WD 40. It's what I use, and they pay me the big money to do it.

    Thanks Bill,

    I did not know scotchbrite would harm a polished surface. I used it on an old turning lathe that the fomer owner had kept in an unheated shop. It was very good for removing the surface rust. Just did not know it was that agressive. Regards, Kirk

    Yes. Gret Scotchbrite is what Ruger suggests using to match their matte stainless finish.

    One more question. For the really bad knife should I let the wd40 soak in for a while? Or does it matter?
    Thanks again

    I use a Arkansas soft honing stone
    to work out shallow pitting.
    Time consuming, but good steel is worth it.

    When presented with a moderately rusted but still otherwise good knife on which I wish to preserve whatever remains of the underlying finish, I first attack the rusted surface with water and either Zud brand or Bar Keepers Friend brand of non-scratching powdered kitchen cleanser. Both of these cleansers contain oxalic acid which slowly chemically dissolves only the rust and leaves the original metal finish intact. I make a thick slurry of the water and cleanser on the blade and work it about first with my fingers and sometimes later with a damp rag. After generally no more than two or three such applications I can at least see precisely what it is I am working with on the blade. On heavily rusted knives such as some of yours, I would also do as previously recommended with the oil and 0000 steel wool process as the first step to get the rather heavy accumulation of surface rust off. That would then be followed by a good dose of a grease busting liquid dish detergent to break down all of the residual oil caught in the metal pores. Rinse well and then give the rust dissolving oxalic acid enhanced cleanser slurry a try to get the next layer of rust and rust stain off. When done to your satisfaction, seal the knife surfaces with a light oil. I have also found that the blend of nice smelling natural oils contained in the G96 Gun Treatment product does an excellent job of protecting the surfaces of fine knives from either initial or further rust.

    While we're talking rust, I've got a little issue with my Windlass broadsword getting little spider-web shaped tendrils of rust forming on the hilt and scabbard furniture. It's been coated with WD-40 from day one, regularly re-applied. Any suggestions on a better protectant? This isn't a wall-sword, it's a real (non stainless) steel weapon. The scabbard is wood, covered in leather with steel furniture that matches the sword.
