Hello Gio,
Thank you. This is my eldest panjang kris blade, I did not really restore it but just cleaned it in pure vinegar (8-10 % acetic acid) for about 24 hours with 2 intermediate scrubbings; there are some small pits left but they were present before cleaning.
I attach the pics of another panjang blade before and after cleaning it in vinegar, with the same procedure and a very good result also.
By the way and contrary to diluted mineral acids (hydrochoric, sulphuric, nitric, etc), vinegar is a too weak acid for attacking the bare metal in case anybody has doubts about it.
