Pot of sea not here on stove. What do I do? I put on a small pot of water about an hour ago....

I put on a small pot of water about an hour ago. My cousin come over and said his dog had just run away so I went to help him look for it. I come back to the pot of water in the region of five-ten minutes ago and the water was evaporated, disappearing an oily looking residue, some of it looks light green and crusty. On the burner nearby is this white spot, half the size of the burner itself. I turned the burner off and I'm letting it cool down formerly I do anything with it. Is there any course to get rid of the (burn?) mark? If so, how? What roughly speaking the small pot? I don't have a camera to take pic.s of it, sorry.
How long does the average dishwasher final?
Answers:    Your pot have something in it besides water, probably moved out from the last time it was used. Wait until it cools and next scrub it appropriately depending on what it is made of. The spot on the burner may go away when it cools off, or the pot's finish may own melted onto the burner. I'm guessing it is an electric stove? If it is, and if the spot does not go away, the burner can confidently be replaced. It will pull out of the stove just similar to an electrical plug pulls out of a wall outlet. Take it to a home building/repair store (like Home Depot, etc.) and buy a new one EXACTLY like it. Take it home and plug it within where the old one be.
