This other guy demonstrates a cleaning with Andre’s Pencils/Crayons. (I’ve used these on some stubbornly encrusted old Roman bronzes.)

There’s another video of a guy using hypodermic needles and a microscope. It was very memorable, but I can’t seem to find it.
Some of these videos show cleaning using applications of chemical-looking goo. I don’t know anything about that, so I can’t recommend it.
I have some good news for you. There’s a whole genre of cleaning videos.
This one uses the toothpick method. https://www.youtube.com/watch?v=RSrEiwEIURM

I dont care about the process or how they look, I just want them to display a before and after in museums for preservation of history
