grease build up

Forgot happy 4th!

Simple Green! You can get it at a grocery store or at a home center or lots of other places. It’s a grease cutter and general purpose cleaner. Comes in a spray bottle so you can squirt it up into the vent and wipe it down. It is water based, not a petroleum solvent so you can use it anywhere. Won’t damage cured finishes, etc. My mother in law swore by it. My first use was to get the cosmoline off of my new table saw several years ago. Now I buy it by the gallon.

Mr. Clean makes a heavy degreaser too. It works. The best
way to degrease is with a steam cleaner I think but that
would lift the grain under the finish. For metal paint I
think steam would be safe. Simple Green, Mr. Clean,
both involve a lot of elbow grease cleaning stove hoods.
(I’ve cleaned a lot of greasy rental property kitchens)
