Wooden decks are significant investments that add value to your home. For this reason, proper care and maintenance of the deck should be done to make it look better and even extend its life. Unfortunately, the deck is usually exposed to harsh elements like the sun, rain, snow, and dirt and debris. This makes it weak and changes its color to grey.

Using a pressure washer to clean your deck can help you strip solid deck stain, remove dirt and grime quickly and help restore its original look. Apart from using water more efficiently, pressure washing a wooden deck will save you the work of manual scrubbing, which can be tedious.

However, it can be a daunting task to select the right washer for your wooden deck. This is because the wrong machine could blast your deck.

Here is a guide to help you when selecting a pressure washer for deck cleaning.

Things to Look for in a Pressure Washer for Decks

  1. Electric or Gasoline Pressure Washer?

Deciding whether you want to go with electric or gas pressure washers is of vital importance because this can either make or break your cleaning process. Ideal Pressure Washer indicates that electric power washers are best for cleaning small decks as they usually provide between 1000-2000 PSI. They are also quieter, lightweight, and compact, as well as require little maintenance.

On the other hand, Gasoline pressure washers can blast away stubborn dirt on large decks and other areas. This model is best for you if you are looking to clean more quickly and frequently.

  1. Cleaning Power Of The Pressure Washer

Deck Cleaning

One of the most important things to keep in mind when choosing a pressure washer for your deck is the pressure (PSI) and flow rate (GPM), which constitute the overall cleaning power of the machine. Different types and sizes of washers have different PSI and GPM. Note that the higher the PSI and GPM, the more power the machine can tackle heavy jobs and stubborn stains.

When it comes to deck washing, less pressure is recommendable; otherwise, your wood can be damaged. Hence, if you have softwood, go for a washer with 500 PSI to 600 PSI and 1200-1500 PSI for harder woods. Also, it is recommendable to use cold water power washers that fall in the range of 1500-1800 PSI. This is because hot water pressure washers are likely to raise the grain.

  1. Nozzle Tip

Different pressure washers come with different nozzle tips that you can choose from. The 25-degree nozzle tip is the best choice for heavy-duty deck washing. The 40-degree tip can also be used since it is made for light cleaning jobs. However, please do not use the rotating brush with this tip; otherwise, it will lift the wood fiber, thus creating a rough surface.

The 0-degree tip is not recommendable for deck cleaning since it produces a concentrated spray pattern that is likely to scar or damage the wood. The 15-degree tip is best for tough cleaning jobs like washing concrete, driveways, and patio. Note, always keep the wand in motion while still spraying to prevent damaging the wood deck.

  1. Tools and Accessories

For effective and quick cleaning of your deck, invest in a pressure washer with the right tools and accessories. Pressure washers that come with a soap tank are a good choice since you won’t need to use separate containers. The right brush will make a difference, as well as leave your deck cleaning project sparkling.
