Nital, 2%.
You can get it on Amazon, but all companies I tried to contact were ready to ship it only to a commercial address.
A friend of mine, who is a VP of a metalworking company, buys it for me.
If you have connections with chemistry lab, metal working company, professional blademaker etc, you are in luck.
No yucky brown stuff of ferric chloride!

Thank you all !!

I'll try to find Nital 2%,
don't seems easy to find.

I work in an highschool; I will ask my colleague teaching physical if they have nitric acid in the laboratory and mix it with ethanol...( sure glasses, gloves and laboratory fume hood).
We'll see ...

Hello,

I found concentrated chlorydric acid ( 20%) but no nitric acid,
I read it attacks strongly iron,
Do you think it can be used too ? ( 1-2 % ?)
