[QUOTE="Fnx50, post: 449220, member: 4872"] I use an ultrasonic with Activax Cleaner. Works a treat but if you use it, be very, very careful as it is poisonous and caustic. Jewellers use it to clean jewellery. It brings silver coins up a treat. Like I said, be very careful with it and rinse out the ultrasonic after use. It costs about $20 for a 500 gram container. Use just a couple of grams (Just the tip of a teaspoon). It will last a loooonnng time if you keep the container well sealed. I take some with me in a sealed container when I go detecting. I throw in any coins I find, add water and let the vibration, during the drive home, start the cleaning process [/QUOTE]
