While it can be a good idea to learn how to pressure wash brick to remove oils, algae, and debris from the surface, pressure washing isn't a good option for getting rid of white stains on brick. While you may get good temporary results, pressure washing can actually make efflorescence worse once the brick dries because the process pushes salt deeper into the brick. In addition, the intensity of pressure washing can damage brick.

Before pressure washing, you can spray your deck lightly with a deck cleaning solution made of equal parts oxalic acid and water. Oxalic acid has a brightening effect that will lighten mold stains and return the deck to its original freshly-sawn look. Allow the solution to sit for about 20 minutes before pressure washing so it has time to take effect.

While a pressure washer is certainly powerful enough to remove old and peeling paint, this is not a great idea to do yourself. The pressure washer is so powerful that you could actually damage the walls as you strip away the paint. It’s best to leave paint stripping to the pros. 

Yes, it is important to wash your deck before painting to ensure the paint applies well and adheres properly. While you don't have to use a pressure washer, it is one of the most efficient cleaning methods. Pressure washing can quickly remove dirt, wood fibers, and flaked paint, getting deeper into the wood than manual scrubbing. You can also clean the deck with a stiff broom and a cleaning solution. Regardless of the method, a clean surface is essential for good paint adhesion. Make sure the deck is completely dry before applying any paint.
