I might have a go at trying to clean the blade up following some of the posts here on Keris cleaning (but maybe without the arsenic). When I was in Malaysia I spoke with a Keris maker in Kuala Kangsar who mentioned using a tamarind solution.
So far I have managed to clean up slightly rust speckled blades and strip gun blueing (the gun blueing strip was not intentional, left it on too long).
When I get a free stretch of time I'll take some photos.
If the keris cleaning process by a novice is not advisable please let me know, all advice is appreciated.
