Vinegar is a versatile cleaner used around the house, in boats and cars, and in foods. Corn alcohol is mixed with other nutrients and fermented to create white vinegar or a form of ascetic acid. You can use vinegar to find out if a ring is real gold or not. You can also use white vinegar to clean metals.
Things You'll Need
Pour the white vinegar into your glass cup. Do not add water.
Place the gold ring into the cup of white vinegar.
Let the gold ring sit in the cup of white vinegar for approximately 15 minutes.
Remove the gold ring and rinse with water. Real gold will shine while fake gold will change colors in reaction to the ascetic acid.
