- 1 16-ounce canning jar*
- 2 oranges, peels only (eat the insides!)
- White vinegar to cover
* You may vary the jar size. Just choose one with a tight-fitting lid, and then fill it with peels and cover with vinegar. Also, feel free to experiment with peels from other citrus fruits, like lemons, limes, and grapefruit.
Tip: I have used vinegar to clean our granite countertops for years with no ill effect, but some people recommend against doing so. If you are unsure as to whether vinegar should be used on a particular surface, test it in an inconspicuous spot. For anecdotal information, you may also wish to skim through the many comments below.
