Exhaust duct from microwave fan

[s_N_s]

How or what do you use to clean the exhaust duct that is connected to the exhaust fan on the microwave? I know to take the cap off on the roof but is there a special cleaner to use? any advice how to go about it would be great.

Whenever there is cooking there is grease! It matters not how little eventually some of it will get sucked through the vent and some of that will deposit itself around the opening. Dirt will naturally accumulate wherever that grease lands.

Wish I could say the same. I know they make ductless fans but ours is vented. I have never taken off the vent cap to look down there but the roof is just black around and only that area. We have filters an the face of the fan and they're clean. That's what makes me scratch my head regarding the dirt on the roof. :h
