Your Museum Coach: Cleaning an artifact

[@sismissismis9173]

Nice video mate. I have a question about cleaning ancient artifacts. When i find artifact, bronze has green patina. But when i look the same artifact in museum, it has almost gold patina ( real colour of bronze ). So i would like to know what are they using to clean artifacts, without demagin them. Thank you for your time.
