All my appliances are SS. I use a spray stuff called Stainless Steel Magic. I either got it at the grocery or at Dollar Tree, since those are the only 2 places other than Sam's that I buy cleaning stuff, and it's too small a bottle to have come from Sam's. It cleans and polishes.
For quick wipes, I buy these packets of Orange Wipes at the Dollar Tree. They work great on the all of them and don't streak. I have a 6 burner gas cook top, that the top is more shiny black,than stainless, and I use them to wipe the burner areas out too and even that doesn't streak.
