my silver testing solution does not seem to work any more - How can I refresh it ?

Hi guys,

My ( orange) silver testing solution is 2 years old.

I think it is no more operational.

How can I refresh it ( if it is possible)?

Thank you in advance

hi Dave,

Do you think I can refresh the solution with some drops of nitrics ?

I've never tried that. I think I remember kadriver mentioning refreshing his Schwerter's solution, but I don't recall what he did. try a search with his name as the author.

As long as it is orange, no expiration. When chrome is not in the 6th valence, it is green
