So would it be beneficial to use with regular sterling? Are there any dangers (does it eat holes in clothes) and where do you get phosphoric acid?
I am told it works extremely well with sterling, much better than Sparex.
I haven’t tried it yet, but plan to. It can be ordered from chemical supply
companies, such as Van Waters and Rogers. I don’t think it eats holes in
cloth either. How bad can it be, it’s an ingredient in Coke.
