Making a Tarnish Preventer


How can I make a solution that prevents tarnish coming back on brass and silver pieces? Thank you, Luty

You may protect brass and silver parts in the following ways.

1) Coating the articles with a very thin layer of transparent organic material. Contact: Enthone OMI

2) Giving the articles a chrome-conversion coating using sodium chromate. Contact Technic and ask for Protectox I and Protectox II solutions.

3) Request de-oxidized or tarnish resistant alloys for manufacturing these articles. Contact United Precious Metals.

I hope the information helps you.
