Mint State Restoration

DIRECTIONS FOR USE – PLEASE READ CAREFULLY – THEY ARE IMPORTANT!

Shake well before using.

Using a plastic or glass container, pour an amount sufficient to submerse your coins in about a centimeter of the liquid.Let coins soak for about 15 minutes, then look at each coin and check what effect has occurred.The coin type (bronze or copper), and the level of dirt and verdigris will determine how long to soak.For copper coins, look for signs of tarnish removal, which can occur fairly quickly.Make sure not to leave copper soaking for too long, or you run the risk of removing the patina.For bronze coins, dirt and verdigris are the predominant issues, and typically require longer soaks.Check bronze every 6 hours or so, making sure to watch for signs that the cleaner has penetrated to the coin surface.Coins with especially heavy dirt, corrosion and verdigris should be removed and cleaned with a soft brass brush after a 24 hour soak in clean water, then placed back in the solution until the desired effect is achieved.

TIPS and TRICKS:

For lighter cleaning and patina saving/restoration, it is important not to allow the solution to settle, as it will become highly acidic towards the bottom of the container.For heavy duty cleaning (removing corrosion, verdigris), let the solution settle for an hour or so before dropping the coins in.Make sure the coin being cleaned is exposed to both sides, either by turning during the soaking process, or by placing it in a way that will allow both sides of the coin to be exposed to the solution. While the coins are soaking, it often helps to stir a little to help loosen dirt.This is especially effective for coins with verdigris.Also, keep a lid on the container while you soak the coins, this will help prevent evaporation.

Copper coins sometimes turn a pinkish color after soaking for extended periods of time, which may not be desirable.To restore patina to a copper coin, place it in the soaking container along with a coin that has verdigris (green corrosion) on it.Soak the coin for about an hour, then remove, but don’t rinse it off immediately.After about 24 hours, you should see some of the patina return.Another way to get the color to return after soaking is to slightly heat the coin evenly, until reddish color returns.If you overheat, then you’ll need to dip the coin in the cleaner for a few seconds and try again.

Mint state works to loosen dirt, corrosion, and verdigris from dirty coins, however, it is still necessary to wipe or slightly scrub residue from the coin’s surface.Use a toothbrush or soft brass brush with dish soap under running water.This will also help remove residual cleaner from the coin’s surface.

PRECAUTIONS:

In case of eye contact, check for and remove any contact lenses. Immediately flush eyes with plenty of water for at least 15 minutes. Cold water may be used. Get medical attention.In case of skin contact, immediately flush skin with plenty of water. Cover any irritated skin with an emollient. If irritation persists, seek medical attention.Use in a well ventilated area.
