Thanks André. These are interesting, but i am confused about some of their methods.
In the first video they are cleaning the keris with the hilt attached, which seems very odd to me. I suppose there is a possibility that the hilt had been attached with some kind of adhesive and that they did not want to go through the trouble of removing it. But in that case, i this were mine, i believe i would have wrapped the hilt up as securely as i could in plastic wrap to protect it from the lime juice.
I also find it curious that they go to the trouble in both videos of first peeling the limes before juicing them. Seems like a lot of extra trouble. Is anyone aware of any negative effects if the lime is juiced while still in the rind?
In the second video they work on a naked blade and go to the next step of applying warangan. The first thing i noticed is that they don't bother to clean the blade back to "white", removing ALL the previous warangan, before proceeding. I have always been taught that this is essential to the process in order to get a good stain. Also interesting that after the warangan they apply cream soap. Perhaps this is supposed to help neutralize the acids. I have always used a slurry of baking powder to do that so using soap at this point is foreign to me. While the before and after images of their warangan process is indeed noticeable i have the feeling that a better stain is possible for this keris.

Sonobudaya comes up as a risky site, I dumped it.

First youtube, no comment

Second youtube, fair job

both youtubes were pretty abbreviated processes, I doubt that in the hand I would be satisfied with either result, these were just "touch-up" jobs.

the reason for peeling the lime before squeezing is that you can extract more juice from a peeled lime than from an unpeeled lime, especially if one does not own a lemon juicer.

personally, I like to avoid staining an older blade if it is reasonably free of corrosion and the pamor can still be read, often a wash under running warm water with dishwash detergent, and then a WD40 spray will give an acceptable result.

I do not use anything to attempt neutralisation of acids when I do an arsenic stain, I rinse thoroughly under running water & massage with my fingers, I pat dry with a lint free cloth, & I sun dry before oiling.

I do use bicarb slurry when I stain with ferric chloride, but we do not use this on tosanaji.
