Instructions On How to Clean Algae

Before pressure washing any surface you should first make sure to wear closed toe shoes and eye protection. You may also want ot wear old clothes as you're likely to get wet during this process.

Make sure not to hold the pressure washer too close to the surace you are cleaning as you risk damage. If the surface has a directional grain (like a wooden deck) work in the same direction as the grain and not against it. It will look better. 

5. Apply Cleaning Product to the Area

This is mostly to minimize grow-back. If you take the step to add a chemical cleaner to the process it could be 3 or 4 years before you need to repeat the process instead of once a season. 

A good tip for cleaning product is to apply from the bottom up as this lessons the chance of it leaving steaks - this is particularly relevent for cleaning products that contain bleach. 

Never put a cleaning product in an internal tank in a pressure washer if it contains bleach. Instead use a foam cannon or simply a hose with cleaning solution attached. Product that contains bleach with quickly damage the internals of your pressure washer. 

6. Rinse

Rinse off the chemicals with your power washer lightly spraying the area and then focus on repeating a thorough clean to make sure you don't leave any marks.

Now rinse off the surrounding grass and plants to make sure any debris and chemicals are washed away.
