Hello I'm newbie on the forum,I'm french and my english is not terrible, so sorry.
I went in indonesia (java et bali) 15 years ago, many times and I bought some kriss.
Today I decided to restore and repair it, so i need help
First to clean and stain the blade, what is the process exactly, with lime juice,arsenic,realgar(waranga)?
Thank you-Terima kassih.
