NihontoEurope Posted December 10, 2013 Report Posted December 10, 2013 Hello all, I recently had a bad experience where 2 of my blades were abused (probably by a photographer at an auction house) when they were out of my personal control. The blades have fingerprints on both sides and I would like to ask before I go ahead with a clean-up operation. I have a few ideas, but I feel it is good to look for other ideas. The prints have been on the blades for about 3 months I guess. What tips and tricks do you think would solve the problem? Any comment or suggestion will be gladly accepted.

One total screw-up is enough. Thank you /Martin Quote
Mark Posted December 10, 2013 Report Posted December 10, 2013 have you tried chogi oil? maybe leave it sit on the spots for a day? After soaking light uchiko? that is what I would do first Quote
Drago Posted December 10, 2013 Report Posted December 10, 2013 3 months??? The longer they are on there the larger the risk they won't go away! Use acetone. Removes oil (choji and human) and cleans the blade while it's at it. Oil the blade afterwards. Quote
cabowen Posted December 10, 2013 Report Posted December 10, 2013 After that long, they might be etched in... Quote
Min Lee Posted December 10, 2013 Report Posted December 10, 2013 I don't understand why an auction house rep. wouldn't know to wear a glove at the very least, when handling a blade... that would upset me very much. anyway, would Noxon be a feasible option? I used it to clean off some rust spots on a production sword I used to own and it worked wonders. Not sure how safe it is on a Nihonto but I got the stuff because I heard some Nihonto owners used the stuff on their swords... Quote
Jean Posted December 10, 2013 Report Posted December 10, 2013 Years ago, I had this problem. Uchiko did the trick but they were much fresher. Quote
Brian Posted December 11, 2013 Report Posted December 11, 2013 In order to prevent a debate over a touchy and serious subject, I have changed one word in the original post to "abused" I feel this is more suitable to the matter at hand. Let's please leave it at that without further discussion. Brian Quote

NOPE - would use as suggested Isopropyl alcohol first - then uchiko and oil - maybe acetone or lighter fluid if tough but should be done ASAP after they appear Quote
tesscoothome123 Posted December 12, 2013 Report Posted December 12, 2013 Hi all, If tough try lacquer thinner. I just used this on some tough fingerprints on Monday. It evaporates quickly and leaves no residue with a clean cloth then oil. Regards, John Quote
Surfson Posted December 12, 2013 Report Posted December 12, 2013 I would try choji first, wiping, then uchiko, then another cycle if necessary. If that doesn't work I would try acetone, which I have found is a great solvent for almost any oils and doesn't seem to harm blades. The main goal is to find a solvent that dissolves the skin oils. Choji can do that but acetone will be better. Quote
