Almost had a housefire a few weeks back. We left a Lasko box fan (that we use for white noise while sleeping) on during the day and when we went to go to bed there was a horrible burning smell coming from it and the motor was groaning and the blades were not turning. Clearly the motor died or botched somehow but since it was left on it was overheating (the fan was hot to the touch!) and spewing a burning plastic smell all over the house.
Obviously I threw the fan away, but weeks later the burning plastic smell remains. Health considerations aside, is there anything we can do to get rid of this smell? Leaving the windows open and running fans to air out the upstairs isn't really an option because we're heading into winter, the price of heating oil is high and its been in the low 40s consistently for the last week or so.
