Stainless steel... rubbing alcohol to clean if it leaves any streaks just buff it a little with a clean, dry soft cloth (or a paper towel
: ) and you can make it shine by rubbing with a little oil as barista and weebitty2 mentioned; rust spots come out with a paste of cream of tartar and lemon juice (if you have a ss sink); club soda can remove heat stains (if you have ss pots or anything)
Glass... if this is like the glass oven door or a stovetop it could be greasy or oil residue from cooking so you'd have to do something to degrease it (maybe a little dish soap or something) but assuming it's clean and all a chalkboard or dry erase board eraser--that you never you use(d) for anything else--will take out the streaks
