Smoke coming from oven I like to bake chicken breasts in a glass container with a layer of vegetable oil at the bottom. 

I bake at 500 degrees for about 20 minutes. 

Once I rubbed a bit of Worchester sauce into the chicken and baked it and this caused smoke to billow out the oven. 

Now, each time I fire up the oven, my entire house is filled with an acrid smoke. 

How can I get rid of this problem?
Probably time to clean the oven. Not sure the Worchester had anything to do with it other than timing. We bake stuff with Worchester all the time with no issues. Set it on self clean and see what happens after that.
