Olive Oil?

[Danketch]

haha- boil it- or the blade @least in water with some vinegar maybe- then soak in acetone for a day or so. Never had to deal with this issue before but I think that's how I would handle it.

No Olive oil! When it goes rancid, it can make you poop like a goose! Also gets stinky.
That also goes for all of the other plant based oil's i know of.

Mineral oil. just a light application on your knife and cutting board works great.

So, what's the best way to remove the rancid olive oil? I just purchased a second hand folding knife that's pretty stinky. :barf:

It's a very difficult process to get the rancid oil off without destroying the wood.

A heavier degreaser really scrubbed in with a textured pad (ex: most dish soaps are degreasers), a lemon with salt using the lemon as the scrubber, vinegar, and diluted bleach are sometimes used here followed by then applying a generous few coatings of the correct oils once the wood dries.

Even then, results generally are not great and with most mainstream, thinner, and not very expensive cutting boards that many people have, throwing them out is generally what is advised when this occurs.

Refinishing the wood is another option, or having a knifemaker replace the wood with new wood is an option if refinishing isn't really practical.

Get some rubbing alcohol, disassemble the knife and clean away:thumbup:

alcohol cleans up dirty micarta and g10 very well too...

The one upside with most plant-based oils is, most will wash away if cleaned up like your kitchen knives. Wash with warm/hot water and dish detergent (Dawn, Palmolive, etc). If the oil has been soaked into wood or similar material for some time, it may take a few washings to get rid of most of it. At the very least, any issues of smell or stickiness will diminish with a few washings.

My mother has an old block set of walnut-handled Chicago Cutlery kitchen knives. She treated the walnut handles with vegetable oil for YEARS, and they had become somewhat sticky to the touch. The oxidation of the oil also generated some verdigris (green corrosion) around the brass rivets in the handles. In recent years, I don't think she's oiled them much anymore, so the handles aren't so bad anymore after some cleaning up with dish soap and warm/hot water.

Yup, as chef you run your knives through lots of things roasted in all sorts of oils, aside from having a sanitized hot water bath to clean your tools on your station while you cook (as all good cooks should), the above will get the grease out. Other than that vacuum sealing with soapy water and letting it soak for 45 to an hour in a hot water bath will help too. As stated, I like camellia for blades when I can afford it, mineral oil is great too, especially for wood boards and blades. Save the olive oil for cooking.

I've been experimenting with Coconut oil as a simple moisturizer for hands & skin, here in the ever-dry desert southwest; my hands are always 'itching' for some moisture. I've found it can indeed go rancid, if only by the smell anyway. After using a bit of it on my face in the morning (with some in the moustache, directly below my nostrils), it gets to smelling a bit 'off' by the evening, ...

You are probably right but then I assume your skin is a different environment than a carbon blade - I hope David!

Agree, all plant based oils/fat will degrade over time. I think I stick with the mineral oil "soaked" cloth, although I like the idea of brewing it with some bees wax ...

I make wooden kitchen utensils. I have been using Circa 1850 Terra Nova NaturOil on my wood utensils and on my knife hilts. No smells, no nuts and it is like a moisturizer on my hands.

That sounds great, just looked it up. Any risk of getting rancid/bad?

Not at all. It's considered one of the finest wood oils out there, and a very popular protectant for usage on cutting boards and wooden counters as it really works its way into the wood and is very helpful at preventing cracking and long-term water damage.
