Tips for Cleaning a Deck With a Pressure Washer
There’s nothing quite like a clean, well-maintained deck to set the stage for outdoor gatherings with family and friends. Whether it’s a weekend BBQ or simple relaxation, your deck is the heart of your outdoor space. But, just like any part of your home, it needs a bit of TLC to stay looking its best.
One of the best ways to achieve this deep clean and bring it back to life is through pressure washing. This method effectively removes dirt, grime and even pesky mould that builds up over time.
In this post, we’ll discuss the proper techniques for deck pressure cleaning, the dos and don’ts of the process and how professional services can help you achieve the best results.
Is it Okay to Clean Decking with a Pressure Washer?
Cleaning a deck with a pressure washer is generally safe, but as with most things, it’s essential there’s a right and wrong way to go about it. While pressure washing is a powerful cleaning method, if used improperly, it can lead to significant damage. Here are a few things to keep in mind:
Risks of Improper Use
Going overboard with the pressure can actually do more harm than good. Too much pressure can damage the wood grain or compromise the surface, leaving you with more problems than you started with.
Know Your Decking Material
Different types of decking materials may react differently to pressure washing. Hardwoods, like teak or mahogany, can typically handle high-pressure cleaning without damage, while softer woods, such as pine or cedar, may be more vulnerable and require a gentler approach.

Reasons for Deck Pressure Cleaning
There’s more to pressure cleaning your deck than just making it look good. Here are a few key reasons why giving your deck a proper pressure washing cleaning is a smart move:
Remove Dirt and Grime
Over time, decks often collect layers of dirt and debris, which can make them look worn and dull. A good pressure washing effectively blasts away this stubborn buildup, revitalising the surface and restoring its original beauty.
Prevent Mould and Mildew
Damp spots can quickly turn into breeding grounds for mould and mildew. Regular pressure cleaning is essential for preventing these unwanted growths from taking hold of your deck.
Prolong Deck Lifespan
Regular cleaning helps prolong the lifespan of your deck by preventing decay and deterioration caused by dirt and debris. By addressing these issues early on, you protect your investment and ensure it remains in great condition for years.
Prepare for Staining or Sealing
A clean surface is essential when applying stains or sealants. Cleaning a deck with a pressure washer removes any dirt and contaminants, allowing the wood to absorb these products more effectively.
Improve Curb Appeal
When your deck looks good, it creates a welcoming atmosphere that leaves a positive impression on guests. Taking care of your deck also adds value to your property.
Dos for Deck Pressure Cleaning
When it comes to pressure cleaning your deck, a little prep and know-how can go a long way. To ensure you get the best results without causing any damage, here are some key dos to keep in mind:
Prep Your Deck
Be sure to clear the area by removing furniture, planters and any other items. This allows for thorough cleaning and prevents any accidental damage.
Wear Safety Gear
Safety first! Always wear protective gear such as gloves, goggles and non-slip footwear to minimise the risk of injury while you’re cleaning.
Know What Type of Wood You Have
Different wood requires different pressure washing settings, so make sure you know what you're working with to avoid overdoing it.
Know the Appropriate Pressure Setting and Nozzle Tip
Too much pressure can damage your deck, while too low may not effectively remove dirt and grime. Make sure to get familiar with the right setting and nozzle for your specific decking material.
Test Your Pressure and Range
Always start in a small, less visible spot to make sure the pressure isn’t too harsh. This step allows you to confirm that the pressure is suitable for your decking material without risking any damage.
Use a Sweeping Motion
Keep it smooth and steady by moving the washer in a sweeping motion. This technique helps avoid focusing too much pressure in one spot and keeps your deck looking even.
Maintain Consistent Distance
Hold the nozzle a few inches away from the deck surface to ensure consistent cleaning and avoid gouging the wood. Maintaining this distance helps you achieve even results.
Call for a Professional Pressure Cleaner
If you feel uncertain or uncomfortable about clean decking with a pressure washer, it’s always a good idea to call in the pros.
Opting for experienced pressure clean experts means having the skills and specialised equipment needed to guarantee a safe and effective job.
Don'ts for High-Pressure Cleaning
While pressure cleaning can do wonders for your deck, there are also a few things you should avoid to keep everything in tip-top shape.
Too Much Pressure
Higher pressure may seem effective but can end up causing more harm than good. Always use the lowest pressure that still achieves a thorough clean.
Too Close to the Wood
Holding the nozzle too close to the surface can gouge or scratch the wood. Maintaining a safe distance, a few inches away is typically the right distance, for effective cleaning without damage.
Inconsistent Motion
Pausing too long in one spot can create streaks and uneven cleaning. Maintaining a steady motion allows for an even distribution of pressure and helps prevent missed spots.
Start Away from the House
Always start cleaning from the house and work your way outwards to prevent splatter from hitting walls and windows.
Go Against the Grain
Never pressure wash against the grain of the wood. This can damage the fibres and leave your deck looking rough.
DIY Cleaning
While DIY pressure cleaning can seem like a cost-saver, it often leads to safety hazards and unsatisfactory results. It's always wise to consult a professional who can provide the expertise needed for a successful cleaning.

Potential Risks of Cleaning a Deck with a Pressure Washer When Done Incorrectly
It's important to understand that clean decking with pressure washer, when done incorrectly, can lead to various types of damage:
Wood Splintering
Using too much pressure or the wrong technique can cause the wood to splinter, which not only poses a risk to your feet but can also compromise the overall integrity of the surface.
Furring
If the pressure is set too high, the wood’s fibres may rise, creating a fuzzy or rough texture known as furring. This not only detracts from the deck's appearance but can also create the potential for splinters.
Gouging and Scratches
Using the wrong nozzle or holding it too close to the surface can cause gouges and scratches that leave permanent marks on your deck. These blemishes are tough to fix and can leave your deck permanently damaged.
Damage to Sealants or Stains
If not done properly, pressure washing can strip away your deck’s protective coatings, such as sealants or stains. This damage can lead to further deterioration and necessitate additional work to restore.
