I have doubts about cleaning. I may damage it.

Bronze Disease [ Part 2 ]
When receiving uncleaned coins, isolate the ones with the Bronze Disease. It can spread into your collection. Do not put them in contact with any liquid substance, oil, water, and so on.
If you are a new collector, I recommend just isolating it, visit your expert. Scraping it off helps if the item is dry, but if it starts growing when it gets in contact with water that is a problem.
If it already is spreading, or that you are a professional, I advise that you remove it as fast as possible. In two days, it ate through the patina of one of my coins, leave it for a week.
To get rid of it, well, it is quite complicated. Olive oil seems to slow it down, but not much effect on it. Purified water usually cures it, but it may also strip the coin of all its patina.
My best advice, make sure that you do not place the coin into any contact with any liquid substance. If it already is infected, cure it as fast as possible. Consult an expert as fast as
