I know what polish you are talking about. I worked at wendy's for a year and on rare occasions we used the same comercial polish. There are many ways we clean stainless in a resturant without the expensive polish. The best way to give it that shine is by using a green Scotch Brite and plenty of hot water. So if you really want to get your D looking new, I guess you could do the same, just use some very hot water and a pad with a handle so you don't burn your hands. Just my 2 cents, I thought i would contribute to this fast food info that i already know so much about.
