For quicker, simple cleaning. Designed to remove mud/clay/dirt from newly acquired uncleaned coins.
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 neeeded 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! ;-)
