Any hope on something like this?

Serious acid staining here. Trying to figure out if there is any chance of correcting something like this and how.

Hey Brandon, If it's been burned by an acid like Muriatic, there is a product that is supposed to re-activate it so you can remove it. Give me a call and I'll see if I can help you out with this.
