If you are using a pressure washer be aware that if you don't have a special nozzle or head on the tip to diffuse the water it can cause a lot of damage to what you are washing. I have never used more than a just a regular spray nozzle on a water hose for cleaning and I wouldn't even do that anymore because it takes off so much beneficial bacterial. If you make the pond spic and span the fish may become very unhappy.
