After reading several concerned posts in amazing EA&A forum, I realize electric method can remove rust. However, I am not sure if this method is harmful to Koftgari which chance I dare not take. Almighty EA&A, Please help me out.

I am trying this. Seems to work well. Always nervous about using chemicals. I don't think it would hurt your koftgari unless there is rust under it. Do suggest that you submerge entire blade so you don't get a "line."

A very simple and commonly used process with rusty old tools, etc. is to soak it in a solution of 1/2 white vinegar and 1/2 water. After a few days in this solution, the rust slides right of with a few strokes of 4/0 steel wool, or a coarse rag. Sometimes it just rinses off. with stubborn rust, you just let it soak a bit longer.
The downside is that the procedure removes all the rust from the pores of the metal, and if the piece is badly rusted, you end up with open pits. Plus, when you are done, you end up with a kind of raw, pickled finish to the steel. With old tools, etc, you need to re-patinate the metal to make it look right. But it works to get rust out of all the nooks and crannies. It doesn't damage sound steel or iron in any way that I have noticed. Test it on a scrap piece to see how it works.
I don't know if it would be appropriate for use on old blades. I never have.

Looking at the texture and amount of pitting on your blade I would not use any sort of chemical or dipping procedure but would just oil it and rub it down gently with a rag or paper. Keep the patina and just stop it from further deterioration.

Just my opinion!

Thanks for these advice. So kind of you fellows.

At last I think one way to bring the beauty back is to grind carefully.

I prefer a good machine oil and "elbow grease" used with a scrubber sponge and various kinds of cloth material. I have also used lemon juice to bring out the Damascus pattern. Make sure to wash the blade with soap and water after using lemon juice or vinegar. Personally I don't like to see overcleaned pieces.
