Phosphoric Acid


Recommended Posts

It's not hard to order online, but I never had much luck finding it locally. Some folks say they've found it in the paint section of Lowe's and Home Depot, but the stuff I've seen usually has other ingredients besides the phosphoric. There's a Behr Concrete Rust remover that's half phosphoric acid, but I don't know what the other half is. (It could just be water.) Naval Jelly is mostly phosphoric acid, but there's other stuff in there, too.

In your shoes I'd probably order it. Or just buy a parkerizing kit from Brownells and be done with it! :)

Buying the kit kinda takes the fun out of it for me. And thought maybe I could do a decent enough job on materials I already have and be much cheaper than the kit. Thanks

I will probably end up buying the kit from Brownells but wanted to check this route first.
