Wash a generous area around the visible corrosion. No harm in cleaning the whole board. Vinegar and citric acid won't attack the intact parts (obviously don't leave the board sitting in vinegar for weeks or something ridiculous like that).

Removing the socketed chips simply gives you better access for cleaning (and later, drying). Also a good time to check if the sockets or the pins have been affected by corrosion.

Getting rid of excess moisture in some way (dabbing with paper towels, canned air, compressor) is a good idea, particularly from inside the sockets, connectors etc. where water can't easily drain out. Then just let the board dry naturally, preferably standing up on its side. The remaining moisture will be gone within a day, assuming you don't live in a jungle
