Homemeade Formula for Aging Metal - 1 cup of hydrogen peroxide, 1 cup of white vinegar and two tablespoons of salt. Put it in a spray bottle. This can be used on anything you want to create an aged patina...copper, brass, galvanized or steel.
Naturally repair wood with vinegar and oil- Use 3/4 cup of oil, add 1/4 cup vinegar (white or apple cider) mix it in a jar, then rub it into the wood. You don’t need to wipe it off; the wood just soaks it in.
