I am going to try a sodium sulfite solution to get rid of the scale after forging. Any of you guys have a mix ratio for this solution?

Thanks

I just soak in vinegar overnight to remove scale. Soak overnight then scrub with 120 grit sandpaper and scale just comes right off.

I use about 1 1/2 cup to a gal. of water. it works faster if you heat it up, about a one hour soak, longer if there is flux.
