Anyone have a PCGS certified Hibernia pitted picture?

I bought a nice 17775 Hibernia but it has 2 small pits with green(no pvc, but copper patina) I would like to get into a holder. Do I need to remove the corrosion that is common on these coins or will it slab. If I remove it, what is the best method, olive oil and a plastic tooth pick. Then was it in acetone to remove the oil or are there other options.
