Hello Mr. Rawles,
Regarding the man who found his canned food rims rusting in his basement. I can recommend OSPHO, which is a liquid which will upon application changes the rust to a more stable compound. I was in the Merchant Marine and we used it on the ships and it works very well. You can get OSPHO through Amazon.com or at a ACE hardware store. It is basically phosphoric acid [suspended in a coating.]
He may also want to invest in a tabletop buffer or wire wheel to quickly remove surface rust before applying the OSPHO which improves the effectiveness.
Thanks so much for your site, I read it each morning. – Robb M.
