Hi, Looking for some advice. I have fine Sterling Silver box chains that have tarnished in the sun. I have detarnished them with various methods. Nobleclean, concentrated jewellery cleaner, ultrasonic bath. They clean up but tarnish again within days. I bought the Silverbrite unit hoping that would solve my problems but they are still tarnishing within days regardless.

Please help me, I'm frustrated with these chains, I'd love to scrap them but we are talking about 40 or so chains.
