So I have always went for 9260 Spring or T10 Steel when it comes to blades and have never had an issue using the white vinegar and dish soap trick to bring out the hamon a little better. I just did this on a newer T10 blade this morning and there seems to be a rust streak forming at the edge of the blade. It's pretty much trash to me now and I'm kiiinda pissed. Think it was labeled T10 and is probably 1045 or 1060 instead? How in the world would this ever happen?

How do you figure? T10 can rust, too.

Vinegar is acetic acid. The strength with vary somewhere between 5-20% depending on brand. Your rust is due to you not neutralizing the acid completely and/or failing to remove it, don’t blame the metal type. Hopefully you removed the blade from the furniture least some acid is up there too and will let its presents be known at some future date. A mixture of baking soda and water will naturalize acid, chemistry 101 and my heart burn will agree. Give the blade a good rinse of that after treating with the acid. The water your soap was in has more effect on removing the acid than the soap but I wouldn’t trust just just that, as you are experiencing.

And thanks for the heads up on the baking soda, brother. Man I've got ALOT to learn. Appreciate it

So I did the baking soda trick and got the brown out of the blade.. now you can't feel anything when you touch the area with your fingers, and where the little specks were are almost totally gone.. and now it's hard to see, but you can still see them but they arent really brown anymore. Think I stopped the madness before it got out of hand? Or do you think it would still slowly spread over time?

A metal polish like simichrome will probably get the remainder out but will dull your etch. When I etch I use Windex to clean the blade. Twice. There can't be any oil or gunk on the blade before etching. The Windex also will neutralize the acid after etching.

I've done it before but that's where I also messed up yesterday as well lol! i need more reps to fit it in my wheelhouse lol!I'm glad it was just a blade I strike everything with. Thanks for the hand, brother

Or do you think it would still slowly spread over time? Probably not, but keep it oiled and inspect on a frequent basis until you are convinced. Glad that you caught it before it became serious.

I hope the original poster does not mind my posting about a somewhat similar issue I am facing here on his thread. I got a black 9260 spring steel TH sword just over the weekend that took sometime (4 weeks) to get to me. When I got it, the saya fit extremely tight and I saw what I suspect was saya rub blemishes. I was quite heavily oiled in machine oil (the smith admitted to doing this to deal with rust issues he had in the past, I told him next time to wrap in plastic after oiling) and had quite a bit of wood shavings in it. Next day I got the oil off with 90% alcohol and then applied mineral oil to it in a thin layer. A bit later I noticed some spots near the habaki. I started to freak out that it was corrosion (black rust) that could compromise the blade but some folks indicated it looks like residue from the electroplating process or some type of reaction with the oil(s) on the finishes. They are only on one particular spot at this time. Pics included below. Can anyone advise if I am looking at rust or I am just a hyper-observant OCD noob with nothing to worry about? Thanks.

Turns out it just needed a rub with some alcohol. All the spots were gone.
