Will Pressure Washer Remove Algae?

Pressure washers that have a high-pressure nozzle can be used to remove algae!

If you have been looking into buying your own pressure washer, you may have noticed that the product descriptions mention the use of high-pressure nozzles in removing tough stains like algae and mold from hard surfaces.

This may seem to be an effective solution but is there more to it? To know if you can successfully remove the algae by using your pressure washer, you will first need to understand how it works and what factors determine if it will be able to do so or not.

This blog will give some insights on how pressure washers work and if they can successfully be used in removing algae from hard surfaces.


Step 1 – Know the type of algae

You need to know if your algae is growing on hard surfaces or swimming pool walls. If it is growing on hard surfaces, such as driveway, carport and swimming pool then you would need Pressure Washer with 1600 PSI and 5 GPM.

But if you want best results then you must consider selecting pressure washer that has at least 2000 PSI and 2.8 GPM. These types of pressure washers will easily clean off all tough stains including paint scrapes and grease spots in no time.

Pressure Washer will also give shiny look after washing away every trace of stain from paint surface or any other hard surface.


Step 2 – Know how to use your power washer on maximum pressure

In order to remove all traces of black moss, you will need your pressure washer on its highest setting. For example, if your power washer is 1,500 PSI, then you should switch it to 4500 PSI.

Once you have changed your settings, you’ll need to prepare for working with such powerful water pressure. Don’t forget; safety glasses are very important as they protect our eyes from getting splashed by water and/or sharp objects or fragments when using strong high-pressure sprayers in everyday situations.


Step 3 – Choose the right nozzle for cleaning your surface

If you’re going to clean your driveway, siding, or pool with a pressure washer, make sure you use one with a narrow cleaning tip. This will help you avoid damaging things like driveways and brickwork by applying too much water pressure.

Be aware of how far away from the surface you are standing as well; depending on your model, moving back from six inches up to 12 inches may allow for enough pressure without risking damage.


Step 4 – Spot clean rather than starting from scratch

It may sound obvious, but you will get more done in an hour by scrubbing a small section than you will in 15 minutes with a power wash. If you’re going to pressure wash your deck, keep it small.

Pressure washers work best at cleaning on flat surfaces rather than angled or curved ones keep this in kind while cleaning any surface. Pick one area of the house, such as an entire deck or sidewalk, and start there. An hour’s worth of pressure washing is better than three hours’ worth of sweeping. But, once again, the power pressure you use is important.


Step 5 – Clean off as much as you can while the surface is still wet

Once you’ve hit everything with your power washer, use your scraper and plastic scrubbing pad to go over every surface you’ve hit with water. Make sure all surfaces are dry before starting step 6 below.

The longer you wait between steps, the more likely it is that some of your work will begin to peel off or break apart due to natural weathering, so hurry up, and wait as little as possible!

If you do need a short break (like if it’s getting dark), don’t worry too much about it: just get back out there as soon as possible and finish up for another day. Remember: Time = Kill, so try not to procrastinate or put things off until tomorrow!


Step 6 – Use water before using chemicals

To reduce your risk of ingesting chemicals from power washing, wash surfaces with water first. This will soften dirt and grime making it easier for chemicals to lift it away. You should always keep fresh water available while using a pressure washer.

With chemical-based cleaners, always read manufacturer’s instructions and never mix cleaning products together or with other household products as they may react in an unexpected way resulting in toxic fumes or other harmful substances being released into your environment.


Step 7 – Consider using safe and natural products

You should also consider using some safe and natural products when you clean your gutters. It’s very important for you to use some products which are safe for your skin, especially if you don’t wear any protective clothing.

There are many cleaning products available in different stores and online websites. In addition, there are many manufacturers who make it so you can buy their products from home using online services. Here, it’s really up to your preferences which one will work best for you because some of them offer numerous benefits than others.
