I've only used plastic so far. A friend was moving and she gave me her wooden cutting board. I cut something with it, and some grease got on the cutting board. Now I can't remove the yellow spot no matter what I do. What can I do to clean it?

I'm guessing it wasn't (well) oiled. Oiled boards are fairly easy to clean and nothing will soak into them as long as they're cleaned after using.

Might come off with scraping and oiling, so treat the board again. Otherwise the spot is not going to be harmful in any way and cutting boards get marked over time in any case.

[–] cabbage@piefed.social 8 points 1 day ago* (last edited 1 day ago) (1 children)

Maybe fighting fire with fire and setting the whole board with olive oil now would help at least hide the spot. Beyond that, only time and use helps in my experience.

[–] dusty_raven@discuss.online 26 points 1 day ago (1 children)

Olive oil can go rancid and add off flavor to food. Use mineral oil instead. Some people also go with distilled coconut oil, but I still think mineral oil is the best choice.

[–] Atelopus-zeteki@fedia.io 5 points 1 day ago (1 children)

Ack! No petroleum products on my cutting boards! I've used walnut oil for years, as I was told it's the only food grade oil that dries, and doesn't go rancid. I have a lot of cutting boards, wooden utensils, bowls, a few "plates" or "plowls". And I live in a dry climate, so they get oiled up about once a year. I just did the bowls, and wow do they look great!

[–] JohnnyEnzyme@piefed.social 11 points 1 day ago (1 children)

Not an expert here, but food-grade mineral oil is safe for cutting surfaces from every source I've read. It's even commonly used as a laxative.

Meanwhile, from what I gather, walnut oil has a comparatively long shelf life, but it does eventually go rancid, leaving an off smell. But it may be that yearly oiling makes that a relatively moot point, with the new covering the old.

[–] fishy@lemmy.today 1 points 2 hours ago

Mineral oil is definitely safe, just try not to inhale misted particles in large amounts regularly. Pouring some on your cutting board and rubbing it in should be totally safe.

[–] untorquer@lemmy.world 5 points 1 day ago

Should fade over time with regular oiling and washing

[–] core@leminal.space 15 points 1 day ago* (last edited 1 day ago) (1 children)

Add more grease so the whole board is the same color

[–] Fluffy_Ruffs@lemmy.world 7 points 19 hours ago

It's not recommended to use any fat that can go rancid. Mineral oil is usually the way to go.

[–] jerkface@lemmy.ca 14 points 1 day ago* (last edited 1 day ago)

Live with it. Who cares? Many tools develop marks of wear or even a patina. Try appreciate the aesthetic. I love it when my tools have unique weathering.

[–] cattywampas@lemmy.world 7 points 1 day ago

Lots of great comments here but one more awesome thing about wooden cutting boards - you can always sand off a very fine layer to expose new wood if the surface gets too gnarly. Then oil it and use it like usual again.

[–] turdburglar@piefed.social 7 points 1 day ago (2 children)

get you some mineral oil and beeswax. 2/1 ratio. heat them in a saucepan on low heat until combined. pour the mixture into a shallow vessel - empty tuna cans work great. allow the mixture to solidify. use a dry clean cloth to apply the paste to cutting board. let it sit for an hour and then wipe off the excess.

repeat once a month-ish or when the wood starts to lighten.

[–] ODGreen@lemmy.ca 2 points 7 hours ago (1 children)

You can also get pre-mixed stuff if all that is a hassle.

I got a wooden cutting board and a tube each of oil and some stuff that seals it, those have lasted for 8 years now maybe.

[–] turdburglar@piefed.social 3 points 4 hours ago (1 children)

well i’m a woodworker, and as such i relish a good hassle.

[–] ODGreen@lemmy.ca 1 points 2 hours ago

Understandable, I also do things the difficult way in my hobbies.

How to get mineral oil and beeswax out of a saucepan

[–] turdburglar@piefed.social 2 points 13 hours ago

the mineral oil makes the beeswax into a soft paste. it wipes out of the pot quite easily.

[–] Atelopus-zeteki@fedia.io -2 points 1 day ago (2 children)

lol, good luck. also please no petroleum products on wooden kitchenware. smh

[–] turdburglar@piefed.social 4 points 13 hours ago

i mean, ok. but as an actual woodworker, my knowledge base shows mineral oil to be a standard food grade treatment for wooden kitchen implements.

[–] Canonical_Warlock@lemmy.dbzer0.com 14 points 1 day ago (2 children)

There is literal food grade mineral oil for this exact purpose along with lubricating food making equipment. It's basically completely inert and is sometimes even used as a food ingredient. You can straight up drink a jug of the stuff with no health repercussions other than the violent greasy shits you would get from drinking any oil. Just because it's a petroleum product doesn't automatically mean its bad for you.

[–] Fluffy_Ruffs@lemmy.world 4 points 19 hours ago (1 children)

You had me at "violent greasy shits"

[–] turdburglar@piefed.social 3 points 13 hours ago

mineral oil is sold at the pharmacy as a laxitive. so yeah, violent greasy shits.

it’s also cheaper to buy at the pharmacy than it is to buy at the woodworking shops as a finish. same stuff tho.

[–] Atelopus-zeteki@fedia.io 1 points 21 hours ago (1 children)

Can you cite any research, not sponsored by the petroleum industry, that relates to this opinion? Walnut oil is a food product, is made from walnuts, doesn't go rancid, and works quite well for maintenance of cutting boards and other wooden kitchen ware.

[–] turdburglar@piefed.social 1 points 13 hours ago

walnut oil is lovely. it doesn’t penetrate the wood as deeply as the mineral oil + beeswax tho.

[–] slothrop@lemmy.ca 6 points 1 day ago

Sprinkle with salt, cut a lemon in half, and scour the board. Leave for a few hours, rinse and wash with dish soap.
Repeat as necessary, and every few weeks.

Turn it over
