You know when you see something on Pinterest (or Google, or a magazine) and you think, “Wow, that is a great idea! I’m going to try that!” Well, sometimes it’s easier said than done.
I came across an article about cleaning the oil splatters off your kitchen hood from The Manly Housekeeper. The article said to put a little bit of mineral oil on a paper towel, and the oil splatters will just wipe right off. Then looking into it I found another article from One Good Thing by Jillie saying she just used vegetable oil and it worked wonderfully for her kitchen hood, so I thought fantastic! I’m going to give this a try!
I was looking for a quick cleaning project today, and using a little oil on a paper towel seemed easy enough so I gave it a shot! 
I poured a generous amount of oil onto the paper towel and wiped down the hood. 
But nothing happened. And the paper towel was falling apart, so I switched to a cloth hoping it would help.
But it wasn’t doing anything. I started scratching the gunk and it turns out it was really thick. I’m guessing the gunk we inherited on our kitchen hood was about 25 years old. Sadly, a little oil did NOT help get rid of it. 
Remembering the homemade goo gone I made a couple weeks ago, I decided to mix the oil with a little bit of baking soda – roughly equal parts, but a little heavier on the oil side. 
I drizzled it over the hood: 
And scrubbed (I scrubbed A LOT!) and it was starting to come off a little:
But this was not as quick a project as I had hoped. And it certainly wasn’t easy! Just look how bad it was when I scratched it off with my finger nail! (Although, some of that is baking soda… I hope…). 
I scrubbed. For about 45 minutes. 
And when it was all gone, I wiped it all down with a soapy sponge to make sure all the vegetable oil residue was gone too: 
I would suggest covering your stove with a tea towel or something because it gets messy when the baking soda falls off. Yes, I even tried scraping with a fork (not the greatest plan) and toothpicks (not overly helpful). 
After boat loads of elbow grease, look how clean my hood is now! 
So again, here’s the before:
And here’s the after:
Yes, it’s still an old hood, but it works, so we aren’t getting rid of it quite yet.
I think if you have only a little bit of oil splatter gunk on your kitchen hood that the fighting oil with oil technique might work better. By all means, it’s so easy, why not give it a shot?! But with 25 years worth of build up, disappointingly, it did absolutely nothing for mine.
My arms are a little tired, but on the bright side we got rid of the previous owners’ dirt and my kitchen hood is now gleaming!
First and Foremost you’d need to create a shortlist of all the kitchen hoods that fit within your stipulated budget and at the same time it should possess all the features that you’re looking for. This will reduce your list drastically and you’ll be left with a shorter list of kitchen hoods that somewhat match your requirements.
I heard that rubbing alcohol also works – I used this on the kitchen fan screen, and surprisingly it took off the oil (need to scrub a little with a nylon brush, but did not need a heavy amount of elbow grease)
