Turquoise stuff on keycaps (lemmus.org)

Got a Eweadn mechanical keyboard and I really like it. After months of use, however, this greenish teal/turquoise stuff accummulates on the keys I use the most. It also accumulates on the sides of the keys, and it doesn't clean off easily. It seems to originate between the circular cap and the rose-gold plated rims. What is?

I apologize if this isnt the correct community to post this in, i couldnt find a generic 'what is it' community.

Definitely copper corrosion. Rose gold is an alloy of copper and gold, and since it's a mechanical keyboard, I doubt they're springing for super high quality stuff, so it's probably more copper than gold. As another said, white vinegar with a few tablespoons of salt should remove the corossion, but I'm not sure how the rest of the keycap will hold up.
