To make the cleaning concoction, I gathered four orange peels, a bottle of distilled white vinegar, and an old container. I used an old glass kombucha bottle and rinsed it thoroughly. If you want to buy supplies, a bottle of distilled white vinegar costs about $0.12 per ounce on Amazon, and I used about 8 ounces of it, so it's worth $0.96. A 3-pack of plastic spray bottles sells for less than $9.00 on Amazon, which works out to about $3.00 each. I think the kombucha bottle and orange peel are “free” since they are usually thrown away. This brings the total for the spray and bottle to a whopping $3.96, with the spray itself costing just $0.96.
First, cut four orange peels into strips that will fit through the opening of the jar. I poured enough white vinegar to completely cover the orange peels, capped the bottle, and let the mixture sit on the counter for two weeks, shaking it occasionally. After two weeks, the orange peel looked a little gray and faded, but the bottle seemed completely sterile. When I opened it, I was surprised to find that the scent wasn't as strong as I expected, just a light vinegar scent with a touch of orange. I poured the yellowish liquid through a mesh sieve into a plastic spray bottle so I could test it in my oily cabinet.
