How to Pressure Wash a Pool

By Brian Teitelbaum  |  Pressure Washer Expert
Your pool is your escape - a place to let go of responsibilities and float your way to relaxation.

But when your backyard paradise starts looking more like a scene out of Swamp Thing, you find it's hard to relax.

Cleaning your pool with a pressure washer will have you back to paradise in no time, but there are a few steps to take first. After all, you can't pressure wash under water - can you?

Requirements

Only pools constructed of plaster, exposed aggregate or concrete are strong enough to withstand the power of a pressure washer.

Any other type of pool, such as vinyl or fiberglass, must be cleaned using chemical treatments or using non-abrasive methods.

Drain Pool

The first thing you'll need to do is drain the pool completely. Leave some time for it to dry.

Sweep up the debris on the pool floor and cover all electrical components in the area including pump motors, heaters and stereos.

Walls

Wash the walls first, then move to the floor. Working in sections will also help you avoid confusion and help ensure you don't miss any spots.

Apply some pressure washer safe detergent from the bottom up, allowing it to work for 5-10 minutes, continually adding water to any area that starts to dry.

Switch to a delicate, low-pressure spray pattern and flush the detergent and residue from the walls, working from the top down.

Algae

Algae must be removed with a high pressure rinse followed by treatment, which will keep it from coming back. Algaecide, or a solution of bleach and water, will do the trick.

Mix 1-part bleach for 4-parts water, and scrub by hand using a brush. Never run bleach through your pressure washer, as this will cause damage to your machine.

Let the cleaning solution settle in for 10 minutes, then thoroughly rinse with clean water.

Turbo Nozzle

Taking care of heavily encrusted stains may need the extra power of a turbo nozzle. A turbo nozzle will help you blast away pesky build-up with ease, letting you work more effectively.

Turbo nozzles pair a high pressure stream with more coverage by spinning the stream very rapidly. It enables you to efficiently strip hard-to-remove stains from the concrete/plaster sides of your pool with less likelihood of doing damage.
