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!
