Home made ultrasonic cleaning fluid
« on: October 19, 2016, 01:42:36 AM »
I'm not generally a cleaner of coins, but today I rediscovered Mrs B's ultrasonic jewelry cleaner, put away some years ago as she'd run out of cleaning fluid. A quick Google later and I had a basic recipe.
A weak solution of ammonia and washing up liquid seemed to be idea.

This is the result. Took five minutes, so I may be changing my mind.

Nice result, not overdone. Would be safe on silver also ?

Probably not the best coin to try as it had been gilded. This took about 10 minutes.
It's fair to note that the model coin on ly suffered from a build-up of crud. The sixpence had dirt and patination.

I am using water as cleaning liquid, as that is what documentation suggested. Would be happy to try your recipe, if it is safe for the aluminium of the cleaner's container. I suspect Do I understand correctly that you use water, than add some dish washer and a bit of ammonia? Or do you have a more precise recipe?

It's one part ammonia to five parts dish soap, shake well together. Use 50/50 with tepid-warm water in your cleaning machine. I did it in 60 second bursts, the examples shown took about five minutes.
