I trust All Clad cookware and have used your products for years.  I recently boght D3, 3-qt. saute pan and have used it twice.  I love the even temperature as it cooks meats and sauces evenly.  The reason for the 4 star review is the clean up.  After cleaning the pan, I see a residue film that should have come off with a regular scrubbing pad.  I don't want to risk using a stainless steel pad  that may scratch or harm the pan, but a regular scouring pad does not clean it as well.  Any advice?
