Hi all! We bought our new home not too long ago, but after cooking this evening we noticed a dripping stain down the wall by the kitchen exhaust fan. I am guessing it is oil/grease built up on the cover (I am soaking it now) that came back in the wrong direction for this in-wall fan.
What is the best way to clean inside the housing, the fan and then also (most importantly) the wall itself to be sure I’ve removed the build up and stain? I imagine the wall itself is the trickiest part to fix and may require prime and paint. Thanks for any help in advance!
