I was baking a buttermilk pie. I accidentally spilled it as i pushed the oven rack in. The oven caught fire. Now there is a slight smoke smell in the kitchen. I need to get rid of that smell.
You need to ventilate the kitchen. Open a window, and turn on your hood/ventilator fan if you have one. Run it for at least 1/2 hour, preferably an hour.
You're going to need to clean up the spill inside your oven, or it'll burn more each time you use your oven until it carbonizes completely. Wait until it cools and then scrub it with an appropriate solvent and brush or sponge.
