Seems to be working pretty well in some cases. Can't tell they had the crust or that they have been cleaned. Yeah. I don't want to damage the coin at all, so don't want to use anything acidic (which includes lemon juice and vinegar). I just want to get the organic dirt off the coin. I'm wondering if acetone would be a good choice. An ultrasonic bath would be great for getting dirt off. Adapting an old ultrasonic toothbrush as a source could be an interesting experiment.

Silver coins that I had not done a very good job of washing came out of a 5 minute dip in ammonia and a bit of toothbrush work with soapy water looking really good. The dirt was gone and they had a bit more shine, but they still had that old coin look to them. Other coins I had that were stained also came out quite well. I honestly can't tell the coins that I cleaned from the ones that didn't need cleaning. Some of the really crusty ones I went back and forth from 30 minutes in ammonia to 5 minutes in lemon juice. Still working on some of them, but a few de-crusted quite nicely. My one prize 1935 sixpence I would now consider too shiny and there is a bit of bubbly looking damage where the major crust was, but it is still an improvement as far as I am concerned. It was so corroded before I could barely make out the date. I have also been playing with a couple of really corroded pennies. So far they have not been nearly as successful as the silver coins.

From the looks of the rain radar, Timaru and Oamru are getting a soaking and the rain is moving offshore from there.
