Chemist, Bruce Nesset, has done it again! He has created a superb new coin cleaning product, one that we have named "Conservator's Mix".
Why Conservator's Mix? The answer is simple enough. After several months of intense experimentation, we have found that this mix is terrific for either short term or long term soaks. Just a bit stronger than GG's #1 and much more gentle than GG's #3, you'll be pleased to find your precious uncleaned coins turning out better than ever. As seen on the label, you'll have to monitor the soaking time, inter-mixed with frequent brushings...but unlike GG's # 3, if you forget the coins in the soak for 24 hours or even more, little or no damage should occur: in this case, it's all about frequent brushings.
Mix 1 tablespoon (17gms) in 2 cups (500ML) of very hot de-mineralized water or distilled water. Remove from heat and add coins/artifacts and allow to cool. Once cool, add all to plastic bowl and cover. Let rest for 1-2 days, then scrub with a tooth brush under running water. Return to liquid as needed and repeat.
Follow the instructions and dirt and softer clay will soften for easy removal. This product works best in conjunction with dental picks, especially Diamond-dusted Dental Picks and Andres Pencils. ;-)
We suggest that you use this mix for very dirty/crusty coins, rather than coins that should be mechanically cleaned with simple DW soaks.
Like all cleaning tools/products, you too will need to experiment with this mix until you understand how it works on ancient coins in certain conditions.
