9 Uses for Rancid Cooking Oil

9 Uses for Rancid Cooking OilNow, I won’t say that I am cheap, but I never like to see waste. I use everything that I can. As many of you know, the shelf life of cooking oils is not indefinite, so the other day I found some olive oil that was out of date. I got to thinking about alternate uses for rancid cooking oils. Here is the list of uses for old oil.

Lubricant and rust preventative.  It can be used for everything from squeaky hinges to oiling your tools. In a pinch, it would work to protect your firearms.

Lamp oil.  Oil lamps are a good alternate use for rancid oils. They are easy to make and put out about the same amount of light as a candle. Having a selection of oil lamps is a very good prep and lamp oil, like this brand, isn’t too expensive.

Furniture Conditioner and Polishing Agent.  Cooking oils can makes a great wood furniture polish and conditioner. I have used it on butcher block in the past. Combine equal parts oil with vinegar for an amazing mixture that can make old, scratched furniture look almost new.

Olive oil softens and preserves leather.  You can also use it on leather to help restore suppleness, and protect the leather.

Get paint off your hands. Rub some oil into your skin, let it sink in for 5 minutes, and then wash thoroughly with soap.

Protect rattan and wicker furniture. It helps keep rattan and wicker furniture from cracking. Just gently rub some warm oil into the furniture with a soft cloth.

Making soap.  Rancid oils can be used to make lye soaps. This book is a classic for basic soapmaking information and instructions. This would be a good skill to have for TEOTWAWKI.

Animal feed.  Dogs and cats do not appear to be bothered by rancid oils. Add a little to their food and it will improve their coats.

Making Diesel.  Old cooking oils can be processed and burned in diesel engines.

These are the alternate uses for rancid cooking oil that I came up with after a few minutes of thought. I am sure there are many more. Every now and then, somebody I know wants to get rid of old cooking oils. I tell them to mark it as not fit for human consumption and keep it. It may come in handy someday.

If you’re wondering why it’s not a good idea to eat rancid oil, read this.

Try to find multiple uses for everything you store.

    Since we don’t know where you live, can you please tell us what sort of business could use it in our area?

  3. when I owned a tree service, I was always getting pine sap on my hands and in my hair. rather than using a solvent, I would use cooking oil on the pine sap, let it soak then wash my hair or hands with soap as usual. this was on the coast of n. ca. it may not work on high elevation pines. the pitch of pines at 7000′ in the sierras wasn’t nearly as flammable as the pines in coastal california

    Olive oil and peanut oil can be used to soften and preserve leather. Corn oil, canola oil, and linseed oil should never be used on leather. They will dry hard and make the leather brittle. They do make a good sealant or paint base for use on wood, especially if thinned with a little turpentine. Olive oil, alone or mixed with glycerin, is an excellent skin conditioner. Most oils mixed with borax make a very effective rat poison. Oil on stale bread can be used to bait live traps.

    For those who cast theur own bullets and reload their own ammunition, particularly for antique black powder cartridge rifles and revolvers, a 1:3 mixture of vegetable oil and beeswax is a traditional ratio used for patch and bullet lubricant, as well as gun grease for black powder revolvers, going back to the Mexican War.

    You should never use vegetable oil on butchers block, cutting boards, counters, etc; especially racid oil. Rancid means it’s decomposing, ie “rotting”. And I’m not sure I would want to use rancid oil on leather I wore or used in hand.

    Your link for the soapmaking book is invalid.
    Next time, include the title so even if the link goes bad the reader can search for it.

  8. RoBear says:

    You should NOT use rancid oil in soap. It will smell rancid, at least in the after smell (after rinse).
