15º tip — Use for tough cleaning jobs. Good for driveways, patios and concrete.
25º tip — Use for modest cleaning jobs. This is a good choice for deck powerwashing.
40º tip — Use for light cleaning jobs. Best for gutters, surfaces covered with leaves and sand, and general rinsing. We do not suggest using the rotating brush because the it can cause wood fiber hairs to lift and remain on the wood.
There is a definite technique for pressure washing decks. If not done correctly, you can damage or scar wood. The best and easiest way to learn deck wash technique is to practice on old boards. The wand should always be kept in motion when it is close to the wood. Stopping the wand while still spraying water will scar the wood. To avoid scaring, arc the wand up and away from the surface at the end of each stroke. No matter what is on a deck, even if it is just plain dirty, you should use a cleaning solution. Using a cleaner allows you to use less pressure and also makes it easier to do a nice, even, consistent job cleaning it.

Pressure washing and sealing your home's other wooden items such as fences, gazebos, and playground equipment are equally important, as they face the same exposure. Following these simple instructions should teach you how to clean deck properly.
