The Emperor Protects Achievement in PowerWash Simulator

This is completed during the fourth job of the DLC, the Imperial Knight Paladin. On this job, you need to clean the Tilt Shield and the 3 Seals on it before cleaning anything else. You can clean them in any order as long as you don't complete anything else in between. You can pause the game and select them from the to do list to highlight them in game.
