I've already tried carefully working on the crust with a toothpick. Do you have any other tips for me?

First, place it in distilled water for 1 day, then use a fiberglass pen to remove what has already been dissolved. Repeat the process 2-3 times, and this should remove a lot of it. If there is still a lot of crust left, use Marcus Brüche's Silver Coin Cleaner, mixed 1 to 10, as needed. Leave it in for 5 to 10 minutes, use a pen to loosen it again, and repeat.
