conservation

on occasion I get older F-S knives that have light rust on the guards or top nuts. While it is important not to reduce the value by scrubbing the patina off, it is also important to preserve the knife for future generations. Recently I received an India-made WW-II F-S with a steel guard and handle. The joint between the two had developed a small ring of surface rust. To remove it I used the solution shown in the photo. BUT you must experiment with it on a small spot first before using it. I have found it to be gentle on even painted surfaces but your experience may be different so proceed cautiously! I had another knife that was rusting heavily at the guard and this stuff not only removed it but prevented further rusting. I had rust problems with this knife for over 10 years! So be a good conservatoire and try it but be very careful not to remove any original finish. I make no claims, or accept any responsibility for damage to your knife for using this chemical, so be sure to test it carefully. I take the spray can top and squirt a little liquid into the cap. I then use a Q-tip to lightly scrub the rusted area and then remove the rust and liquid with either a clean Q-tip or a Kleenex tissue.
