We've lived in this house for three years, and every once in a while, I'll notice drops of oil on a pan I'd previous cleaned and left out on the stove, or on the cooktop itself. I finally figured out that it was probably coming from the hood, because it seems to happen after heavy rain or wind.
I'm guessing there's a buildup of oil in the vent to the outside and the rain probably gets in and washes it back down through the hood, where it drips onto the stove. Does this make sense and is there anything I can do about it?
It's not frequent, but it is annoying.
