A question about a Keris

[Flavio]

Hi all. I have just got this keris from a swap with a very respectable member of this forum. This is my first keris and i like it very much.
Now, the keris doesn't show rust but the blade is quite opaque. I have already read other threads on how to clean keris (also in old forum), but now i want to ask you if is it so wrong to use iron wool on keris with oil (like i usually use on african weapons). The first two pics show the blade of my keris, the others show how i'd like that my blade was (the third and the fourth one are taken from another thread and is a Lew's keris {sorry Lew }). Thank you
