Now, 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As many of you know, the shelf life of cooking oils is not indefinite, so the other day I found some olive oil that was out of date.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.
