There is a difference between using an acid-based copper cleaner to remove the tarnish and a metal polish to make the copper shine like when it was new. The old Twinkle ads were deceptive. Taking care of the copper was never that easy.
I have a picture of the pan on my phone and I have it as an email attachment, but I do not know how to post either to the site. Sorry. If anyone can send directions, I will try to post the picture. The amazing thing is that deep well pans had little bulges in the sides to accommodate the trivet that was used in different positions to position foods at various levels. All of the other deep well pans were aluminum which is a fairly soft metal, but the Revere pan is stainless steel which is a considerably harder metal and yet it has the same little side indentations. The engineering it took to do that is one of the things that has amazed me about the Revere deep well kettle.
