Our challenge is to find a chemical formula to allow these items not to tarnish. Our items are silver plated, but we need an anti tarnish formula to maintain their appearance. We know about ecoating which prevents tarnishing. There are several ways to prevent silver from tarnishing. E coat is one way and requires equipment and tanks similar to electroplating in addition to special filters and an oven for baking.
Several companies make proprietory chemistry for the coating bath.
This process is best done immediately after the silver plating without allowing the parts to dry. You can also spray or dip your items with clear lacquer.
