Hi nechesh,
First I would like to address that different acids would react differently with different substances. It is a matter of selecting the best acid for the job... To me, harshness is more of a degree of concentration or dilution than which acid is being used (in this case). Notice the concentrations I am suggesting. As to rust removal, I believe I stated in extreme cases (in other words, its already "junk"), and even then, dilution is an option I would suggest (always start with a less aggressive solution).
I can fully understand the Captain's position on what to do with blade that is less than "prime." Being a Japanese sword collector, one is always faces with the dilemma... is it valuable enough to sent it to Japan and have it re-polished at over $100 an inch (plus furniture... so you can rap up $3,000 to $5,000 into a sword real fast) or do something else (especially if the blade is only worth $500 even after being polished).... I have a hand made blade from around 1910, the Japanese will not accept for polish because it is not from the Samurai period (its their law). Now what do you do?
I would not take a "do it yourself" approach with an expensive Pusaka... but on a "reject" piece that I have nothing to lose.... It won't be the Indonesian way and it should not compete with their way, but as a last resort to "save" or bring "new life" to a piece, I think it is worth the experiment rather than shove it in a drawer to let it rust away. Who knows what we may learn? As for the better blades, I agree with you nechesh... let it be done the correct and traditional way.
I will try to post a picture of what can happen if one gets too aggressive with acid. It is a crying shame.
