Hey there 

I've been making some knives and I just heat treated and tempered them a few days ago, but I made a terrible mistake and used burnt motor oil, heavily staining my blades with oil. Has it ever happened to anyone before? And if so, is there a way to remove them without damaging my blades. 

I'm open to all suggestions and appreciate any advice given.

Thanks 

Still have to finish grind and polish the blade right?  Little sanding and you should be good as new.  Keep your eyes open for some used veggie oil.  much nicer to work with.

I've tried sanding but thwre are s9me paets that still are really staibed and I don't want to remove much more material from the blade. And thanks for the vegetable oil advice,  I'll be sure to consider it next time 

Read up on how they use lye to remove seasoned oil from old cast iron pans without damaging the pans.  I would try it on that blade---sure works on my old cast iron!

Of course *safety* please!
