Vinegar is an indispensable kitchen ingredient, often featured as part of salad dressing or as a complement to oil in cooking recipes. Additionally, vinegar serves as a natural household cleaner, weed killer and purportedly even acts as an antidote for various ailments from jock itch to diabetes and constipation, according to alternative health bloggers.
Vinegar can even help restore corroded coins to their former condition, offering an economical and effective method of recovering valuable copper coins that have become discolored over time. Cleaning coins with vinegar will bring back their bright shine and remove corrosion deposits; but before using any home remedy for cleaning corroded coins it is essential that you understand its value before taking steps to ensure its condition does not worsen further.
Vinegar contains an acetic acid which helps dissolve copper oxides that make pennies look dull, making it an effective means of cleaning corroded pennies. To use it for this task, place it in a jar with about 1/4 cup of vinegar and 1 teaspoon of salt; the latter helps the vinegar penetrate deep into crevices of the coin to draw out any oxidation present. Soak for 15 minutes then check it after five. When finished soaking for at least 15 minutes it should have lost its dark colour – once rinse it thoroughly with water then dry it with cloth before being stored away safely away.
Another effective solution for cleaning corroded coins is hydrogen peroxide. Working like vinegar, but more cost-effective and available at most supermarkets, hydrogen peroxide allows you to clean coins that have been affected by corrosion by simply placing it in a bowl of the liquid for 15 minutes and leaving it sit before rinsing it with warm water and drying it with a cloth afterwards.
An electrochemical solution using electricity and water can be another fast and easy method for cleaning corroded coins. This technique is frequently employed by professional coin cleaners; however, you can do it at home too. Fill a small glass container with distilled water, add 1 tablespoon of hand soap, soak your coin for 10 to 15 minutes in this solution, then scrub gently using a toothbrush before rinsing and wiping off again with non-abrasive brush before wiping in small circles with non-abrasive brush before wiping again until you see results!
One more advanced and potentially harmful method for cleaning coins is using 100% acetone nail polish remover. However, this should only be attempted by experienced coin collectors in well ventilated environments and should only be performed when dealing with coins that have suffered extreme corrosion. To use it properly, place the metal piece in the solution for five minutes and soak before wiping down with cloth to remove traces of acetone before patting it with baking soda to neutralize any residual chemicals present.
