Chemical polishing Invar before plating with silver

Can anyone recommend a chemical cleaning process for turned Invar components before they are plated with silver? I am concerned with etch pits, etc., to an existing process which was not developed for Invar but for kovar material.

I am facing same problem. Hope that you have got the right answer by now, since the question put up by you was before 2 years.

I would be grateful to you, if you advise the answer.

Regards.
