    I use vinegar and baking soda. Let it soak a few minutes

    Yikes! Dripping greese sounds to me like an unsafe situation, that could very easily result in a fire. It does happen.

    From the picture, I would say that the grill looks not only very dirty, but rusty. There are also greese stains on the paint around the opening, If it looks this bad on the outside, it is likely that the filter has never been changed, nor has the grill ever been taken off, and the inside gunk ever vacummed, or otherwise cleaned. With anything greesy, there comes a point in time due to deterioration where it is beyong cleaning.

    Do things the safe way- stop using this. Get it taken out. Invest in a new exhaust fan and have it installed. Then you can be in your kitchen and cook with cofidence that the situation is safe.

    My son had the very same fan in his house. We took it down and soaked it in Ammonia in a zip lock bag overnight. The next morning, I rinsed it well with soap and water and used a steel wool pad on any tough spots. It looked brand new and he put it back up and it works like a charm. It would probably be a good idea to then take it down about once a year to keep it clean and not dripping!

    you can also soak it in dishwasher soap, ( cascade ) it will come cleaner, faster, than vinegar. all you need is to put a tbsp. in hot water, in the sink or pan.

      I agree for most filters, since I wash mine in the DW, but hers is chrome and the DW detergent could dull it.

    Option one: remove all parts including the fan blades or filter behind the cover. Place the parts in a container and sprinkle liberally with about a cup of baking soda. Add enough water to just cover the parts and let it sit for an hour or more, rinse and reassemble.

    Second option, remove all parts as suggested above. Place in a zip lock bag and add 1/4 cup ammonia, seal and let it sit for 24 hours. Remove from bag and use blue sponge to remove any residue.

    Let us know which of the suggestions you used and how it worked out for you.

    The center nut unscrews to remove the grill. Cover your stove before removing it. You can soak the grill in hot water and Dawn dish liquid. Scrub it clean. Use a cloth or sponge dipped in hot water and Dawn liquid to clean the fan blades and inside of the fan housing. Make sure everything is dry before putting it together.

    I would sand it down and give it a coat of silver (chrome) paint. I haven't used the chrome yet, but I have the gold. Very real looking!

    I would take it down, wet it & use comet on it. Let it sit for awhile then give it a good scrub. That should work

    I have cleaned bbq and oven grills with the ammonia in a sealed bag, mentioned by a couple of people above. It works wonders! I agree that you should wash all the parts that you can. You may need to shut the power off to check for grease above the fan blades. I hope you have a metal duct and mot a white vinyl one.

    I ripped mine out, and put in an over-the-stove hood with fan that I got a Sears. Was about $70. Well worth the investment. I patched the ceiling.

    I had one of these, and the previous homeowner hadn't touched it in years. I took the grill off (that little knob in the center probably holds it on), and soaked it in a good grease-cutting detergent. Then after the obvious parts were clean, I put it in the dishwasher. What that didn't get, I used Brillo/SOS pads to clean off. Then I cleaned the fan blades inside the best I could (make sure you turn off the electricity to the fan) with a cleaner on a rag, if they're disgustingly dirty/fuzzy (mine was). Last part of the job was to purchase an aluminum mesh filter for it, just place it inside the grill before you replace it. (I saw a Broan 8-inch aluminum mesh filter on Amazon that might fit.) If you can't find an exact fit, buy one that's too big and cut it down.

    The mesh filter keeps the dirt/grease out of the fan in the future, and all you have to do is take the grill and mesh filter down occasionally and wash them.

    Also, the mesh filter looks a lot nicer/shinier through the grill.
