What is the best way to clean an old steel? army clasp knife which I recently bought at a Pop Up Shop in Kelso today?
Googling tells me to soak it in coca cola overnight, amongst many other methods, but I’m a bit apprehensive - have any of you any experience of doing something similar? I don't want it 'museum quality' just cleaner.
It is fortunately not rusty just a little mucky black gunge in places.
Thanks in advance.
