Oxalic Acid

[Gump]

I went looking for oxalic acid, and found that it could be ordered, but that nobody stocked it. Then I hit Home depot and found Behr All in one wood cleaner, which happens to be a 10% solution of oxalic acid. It sells for 12.99 a gallon and works well for removing black spots off of vegtan. I have been getting spots quite a bit after wetting the leather for tooling or molding(tandy hides).

Savogran makes 12 oz cans of powdered OA. Home Depot, Lowes and Ace hardware used to carry it but I didn't see it in a search.

Try Sherman-Williams or other local paint store. Not sure what you guys have up northeast <g>.

It's actually sold as Wood Bleach.

I wonder why you are getting spots? that is usually caused my getting metal or iron filings or some other metal in contact with the leather. A ring or bracelet maybe?

Good luck

Oxalic Acid is carried in most home improvement stores, it is sold as "Barkeepers Friend", it is powdered. 1 tsp in a pint of water is what I mix, one can of barkeeper's friend lasts me forever. It costs less than $2.00 for enough to last a lifetime.

Hi, I get black spots on my leather when I case it. I use Herman oak. I tried buying water cause I thought maybe there was metal in the water. I just did a cantle and it's peppered with black spots. Kind of discouraging. How do you fix it?

Sorry went on and read some posts that pretty much answered my question. Thanks!

Do you just sponge the water and acid on and let it sit?

I just wet the leather and sprinkle " Barkeepers Friend" directly on the leather and scrub it with a damp/wet cloth.  Rinse off.   Works great. You can find "Barkeepers Friend" at any major grocery store in the cleaning what-nots section.

+1 for Bar Keepers Friend...works very well ... I use it like Cseeger does...sprinkle it on rub with a wet rag and then rinse off.

Bought it at Walmart.
