Many thanks in advance.

This is not a proper way of preserving keris (in our native culture) . The usual way is to have periodic washing of the blades if they become rusty and stain with warangan where applicable.

Hi Nik,

I really cannot see the problem you are dealing with from this image alone.

Can you share detail of the dilemma?

I've found the ugliest of surfaces can be put back normal with a citric bath and a toothbrush.
