"Making a Tarnish Preventer"
How can I make a solution that prevents tarnish coming back on brass and silver pieces? Thank you, LutyLuty Nusaputera

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.
