Having problems cleaning newly received gift of Calphalon,contemporary non-stick cookware with hard anodized exterior. While many posts seems to be in regards to cleaning the non-stick interior surface of the cookware, I am having problems keeping the exterior of the pots/pans clean. I have noticed oil and other stains/scratches on the exterior surface which seems next to impossible to get rid of. Are there any type of cleaners or sponges that I can use to get rid of this unattractive stains?
Your experienced help/comments would be most apprciated.
