Some power washer may come with interchangeable nozzles, while others may have an adjustable nozzle to help you achieve the same type of jet. With this in mind, which are the best power washers for decks? Check them out.

Good Luck - We Hope You Find What You Are Looking For

How to Choose Power Washers for Decks

Power source aside, there are a few other things to keep in mind to make sure the power washer you buy meets all your needs.

Hot Water Washing

All power washers use cold water supplied by a garden hose, but some models incorporate a heating coil in the design for heavier duty cleaning jobs. You won’t need hot water to clean a deck, but this feature might be handy if you also plan to clean oily surfaces, such as a driveway or garage floor.

TSS Trigger Gun

This type of trigger turns off the pressure washer if it is not engaged, enhancing its lifespan. Alongside a TSS trigger, you might also want a machine with an auto-shutoff function. This function turns off the unit if the water supply is interrupted, and is particularly useful when you’re using cleanser solution from a tank or container rather than supplying the machine with running water.

Safety Valve

A power washer may not look like a dangerous machine, but the truth is that the stream of water can easily cause injuries. A safety valve, therefore, comes in handy on those instances when you have to interrupt the water supply due to an emergency.

Gas vs. electric pressure washer. Which to buy?

Choosing between a gas and electric power washer is often a matter of application rather than preference. If you live in a colder climate area where mold, mildew, and lichens stain your deck and other outdoor surfaces frequently, a gas pressure washer could be your best bet.

This type of pressure washer can output high pressure and also higher water volume for quicker cleaning of stubborn messes.

A gas pressure washer is also a better choice if your property is really large or if you plan to use it for commercial applications.

On the other side, an electric pressure washer might not be as powerful but comes with a bunch of other advantages. More suitable for home use, electric units are lighter and easier to carry. A smaller footprint also makes it easier to store when not in use, while the electric motor starts instantly and without hassle.

How to Power Wash a Wooden Deck

Whether it’s time to clean your deck before refinishing or you’re just trying to get rid of mold and lichens that have grown on it over the winter, a power washer can help. However, there are a few things to keep in mind if you don’t want to damage the wooden boards.

Selecting the right pressure and nozzle

There are two types of wooden decks, those made of softwood like cedar or pine, and decks made of harder types of wood. In the first instance, you should opt for a delicate pressure washing option with a jet pressure that doesn’t exceed 600 PSI.

Typically, this kind of pressure is achieved with a white nozzle that delivers low pressure but a higher flow.

Hardwood decks can tolerate medium pressure, usually of no more than 1,200 PSI, so you can choose a green nozzle that outputs medium pressure and medium flow.

Always test before starting

Once you’ve selected the right pressure and nozzle, check your machine in an inconspicuous area, such as a stair tread. If the jet is too powerful for the type of wood you have and it gets etched, a stair tread is much easier to replace than a deck board.

Learn how to wash the deck with a power washer

Besides choosing the right nozzle and pressure, you should know that proper power washing of a deck depends on the right technique being used. Here are a few quick steps:

  1. Set the pressure washer on a low pressure setting, around 500-600 PSI, and engage the trigger a few feet away from the deck.
  2. At this stage, lower the wand to about 12 inches from the deck and move the jet onto the deck boards.
  3. Start cleaning with a sweeping motion of the wand, moving your arm from left to right, and vice versa. You may have the tendency to pivot your arm, but you should avoid it at all costs, as getting closer to the surface with the jet might damage the wood.

Start from the right corner

The direction of washing as well as the part of the deck from where you start also matter. For the best results, you should start cleaning from the house outwards and point the stream in the same direction as the wood grains on each board’s length.

This technique should help you clean the boards evenly, so you won’t be able to notice any cleaning edges between the various sections of the deck.

Check if you can use a deck cleaning solution

Whether you’re cleaning a particularly dirty deck or you want to remove as much grime as possible to apply a new layer of wood stain, there are moments when you might want to use a deck cleaning solution instead of just water.

If you want to dispense it as you’re washing, you should invest in a power washer with an on-board soap tank.

Some units are also compatible with separate soap tanks, but some pressure washers can only work with water. Therefore, if you think you’ll ever have to use deck detergent or stripping solutions, make sure to check the specifications of the pressure washer before buying.
