Sword conservation

[A. G. Maisey]

Thanks for that Ariel, I've learnt something.

I've never used tannic acid know nothing about it.

As for vinegar, been using that stuff since I was little kid, like maybe 6 years old. True.It was one of my jobs as kid:- clean the saucepans.

In fact what I use to clean keris blades these days is vinegar, since pineapple juice went bad in this country.
