Verdigris

Plain white vinegar would do it. That's what's doing it in the acidic sugary tomato sauce.

What you do not seem to know is the verdigris is also under the hook where you can not get at it. I have had at least one sling have a build up so thick the rivets broke thru the leather and the leather was rotten. Pecards or nothing else will stop it from forming, only when the acid leach's out of the leather will it stop forming. That takes years!

You can buy it from our sponsor, Turner slings.

Personally, I would contact Les Tamm in Hawaii. I'm told he uses original brass hooks on his custom slings.

Its the tannic acid, used to tan leather which causes it. Some do not use it I understand, such as Mexico tanned leather.

Dave, from what I've read it is cause by the animal oits used in the tanning process, to avoid this they now use vegetable oils?

Never heard that. Have a friend who was a chemist and the tannic acid is what he told me. I just took his word for it. I'm sure something could be found on the internet.

Just don't drop any of that stuff on your wife's white bedroom carpet.

The verdigris is a reaction between the tannic acid in the leather and the copper in the brass hooks. As dave explained, the verdigris you see on the outside has worked out from under the brass, and will continue to do so. I just try to keep it cleaned off with toothpicks until it forms more, and incidentally it is poison. In some cases it will push the hooks off the sling, or the rivets in holsters.
