I used several solvents to clean this padlock. In this case I used Tunap Tunsolve 917 along with Tunap MP101 synthetic grease for the ball bearings + actuator and Tunap MP102 synthetic oil for the wafer cylinder. On other locks I also often use Tunap 366 biological rust loosener before using the cleaner.
