Answering the Question will pressure washing remove deck stains? 

Is Pressure Washing My Deck Safe?

Power washing cleans various surfaces, such as driveways and entryways, with extremely powerful streams of water. Mold, mildew, dust, dirt, and even loose paint can be removed using this method, which is also known as pressure washing. If you have a stubborn stain, pressure washing is a good way to get rid of it quickly and easily. It does not, however, work on all surfaces; some are too delicate to be cleaned with pressure washing.

Pressure washing, like any other cleaning method, must be done correctly to avoid damage or undesirable results. You risk damaging your deck if you use the pressure washer incorrectly.

So, before you dive in, make sure you know what you’re doing. Alternatively, go to Google and type in “pressure washing near me” to find a reputable power washing company that can properly clean and maintain your deck.

Finally, yes, pressure washing your deck is safe, but only if done correctly.

Deck Stains That Are Frequently Used

It’s common for grime to accumulate on your deck over time. It can be unsightly, whether it’s mold, algae, or another type of grime. These accumulations are more common in shady areas where there isn’t much sunlight.

Mildew and mold

Water Damage Algae Rust Other Stains
Allowing damp leaves and other foliage to sit on your deck for an extended period of time can cause staining and encourage mold growth. The longer you leave them, the more difficult they are to remove.

Rusting stains can also be caused by leaving metal furniture and planters out on your deck or patio for too long, especially if they’re wet.

Pressure washing, especially for South American hardwood decks, is an excellent way to remove these deep stains that are otherwise difficult to remove (Tigerwood, Camaru, or Ipe). Otherwise, a garden hose is usually the best option. If stubborn stains persist, go online and search for “pressure washing near me” to find a reputable contractor to assist you in cleaning your deck.

The Wrong Way to Pressure Wash

While power washing a composite deck isn’t recommended, it can be done with care to avoid damaging your deck.

If you get too close to the wood or apply too much pressure, you risk damaging it.

Also, avoid using a cleaner that contains chlorine bleach. It can be extremely corrosive to a composite deck, causing the materials to deteriorate. This can cause discoloration, surface damage, and an exacerbation of mold problems. Here’s a quick tip: Sodium Hypoclorite indicates that the product contains bleach. Replace it with a non-toxic alternative instead.

The Correct Method of Power Washing


Start with a low-pressure nozzle and preferably a fan tip when pressure washing your deck. Start by checking to see if the spray is etching the wood or splintering any fibers.

Also, make sure you clean the wooden boards along their entire length. This will assist you in avoiding any damage.

Here’s how it’s done by the pros:

Ascertain that the pressure settings and tip selection are appropriate for the surface – Professional pressure washers come equipped with all of the necessary equipment. To ensure the best results, the pressure washer settings as well as the nozzle tip will be carefully chosen for your specific deck surface.

Maintain the Proper Distance – Spraying too close to your deck will cause damage. Maintaining the proper distance between the nozzle and your deck is how experts avoid this. They also spray in a moderately fast motion to evenly clean surfaces and avoid leaving unsightly lines. They know not to put the nozzle closer than 12 inches to the wood’s surface.


Use Power Washing Techniques Used by Professionals – To clean your deck evenly, experts will use a sweeping motion while pivoting the wand with their arms. Cleaning is ensured by lateral arm movement. In addition, they always wash with the grain and never against it.

Professionals want to avoid damaging wood fibers when pressure washing, so they sand wood afterward. When wet, softwood fibers splinter, especially on handrails. This is why sanding is done by professionals. This procedure opens pores in the wood, allowing it to absorb the stain or sealer that has been applied. Professionals typically sand the deck with 60-80 grit sandpaper. As a result, the boards are smooth with little to no splintering.
