How do you get the old grease smell out of a built in BBQ?
We have a built in BBQ in our patio that smells like old grease every time we turn it on. Even when we are not cooking, just firing it up to preheat releases this heavy greasy smell that lingers for hours. I have tried degreaser sprays and scrubbing the grates, but the smell keeps coming back. I think it is coming from inside the hood or the burner area. Has anyone dealt with this? What actually works to get rid of years of built up grease smell?
