Deck Cleaner

Are you disappointed with how your deck is aging? It’s a common complaint among homeowners that even after just a few years of use, a new deck can transform into a stained, weather faded platform, darkened in areas with black mold and mildew.

While pressure washing the deck does go some way to improve the condition of the deck, decks do need cleaning with special formulas that penetrate through the surface to lift and remove a build-up of dirt and staining. If you can select the right deck cleaner for your deck, you will likely be surprised to find that even a deck that looks like it should be getting replaced can actually be brought back to its former glory.

Buying Guide


How to Use a Deck Cleaner

First and foremost, you should always read the label on the deck cleaner you purchase your deck cleaner. Then, follow the instructions accordingly. You may wish to prepare your deck before cleaning by pressure washing it, but at a minimum, you will need to remove all furniture from the deck and sweep away any leaves or loose debris. If it has rained, allow the deck to dry out before proceeding.

Most deck cleaners have a concentrated formula that you will need to dilute with water into a large bucket, and the label will inform you of how much formula you need with what amount of water. Some manufacturers recommend a higher proportion of cleaner for more heavily soiled surfaces.

Once diluted, how you proceed will depend on what method of application you are using. If you are using a pressure washer to apply the cleaner, it will need to be equipped with a detergent injection system, and you should follow the directions with your pressure washer on how to use this. You could also use a garden sprayer or weed sprayer to apply the cleaner to your surface evenly, or you could use a standard kitchen mop and a bucket of cleaner to cover the deck.

Once applied, the cleaners typically need to be left on the surface for five or ten minutes, though again, make sure you closely follow the manufacturer’s instructions. Typically, the cleaner should be left long enough to be activated and lift the dirt but not so long that it dries. After the allotted time, the cleaner may then need to be scrubbed or simply washed off.

If you have to scrub your cleaner, this should be done with a stiff-bristled brush. Focus on particularly heavily soiled areas of the deck to work in the cleaning solution. If your cleaner is one that requires scrubbing, its best to work in small areas to prevent any cleaning solution from drying before you get around to scrubbing it. Cleaners that don’t need to be scrubbed can be applied all at once and then simply washed away with water from a garden hose.

Once washed away, allow the deck to dry completely before you judge the effectiveness of the cleaner. Some decks might need a second application of cleaner if they were in very bad condition. Once cleaned, be sure to protect your newly revived deck with a stain or protective wax to prevent future damage.

Benefits of Deck Cleaners

Maintain Aesthetic Appeal

Decks obviously spend their entire lifespan outside, leaving them exposed to the elements. UV rays, as well as rain and snow can damage your deck by fading and graying it. Falling leaves and other garden debris can lead to the build-up of dirt, as well as mold and mildew, that all create an unpleasant-looking deck. Deck cleaners revitalize the look of your deck, restoring it to its former glory and improving the look of your outside space.


Remove Slippery Substances

Mold, mildew, and algae can build up on your deck over time. Not only do they leave unsightly black and green stains, but they also make your deck a hazardous area to walk on. Mold, mildew, and algae make decks slippery and an unsafe place to be. Deck cleaners will remove these substances and leave you with a deck that is once again safe to walk on without danger of slipping.


Remove Health Hazards

As well as creating a slippery surface, the presence of mold and mildew create other health hazards. Mold and mildew are associated with respiratory problems and other health concerns, so it’s important to remove these with deck cleaner for the health and safety of your family and pets.


Increase Property Value

A deck in poor condition can really bring down the whole look of your property, especially if your deck is on the front of your home and affecting its curb appeal. Reviving your deck with a deck cleaner will make your home look in better condition and give the impression to prospective buyers that your home is well-cared for and maintained. It can increase your property value and make it more appealing to buyers.


Extend its Lifespan

Deck cleaner can extend the lifespan of your deck by removing elements that degrade the wood over time. By ridding your deck of these elements that are slowly breaking down your deck, it will last longer and save you money from having to replace your deck more frequently than necessary.


What to Look for in a Deck Cleaner

Special Equipment Needed

cleaning a deck with a power washer

When buying deck cleaner, you need to check the instructions concerning what you will need to complete the application. If you have a compatible pressure washer, you may want to look for a cleaner that is specifically designed for use with a pressure washer. If you’re looking for a deck cleaner that does not require any special equipment, you should seek out a cleaner that can be applied with a mop or garden sprayer. If the cleaner needs to be scrubbed in, you will likely need to purchase a new stiff-bristled brush to ensure the job is completed properly.


Surface Suitability

Some deck cleaners are made specifically for use with timber decks, while others are for composite decks. Ensure you check the label so that you buy the right cleaner appropriate for your deck. Many deck cleaners are versatile, and will also be suitable for use on vinyl, metal, rubber, or paving, so you can use any leftover deck cleaner to wash your siding, your driveway, or even your car. Always check the label to be sure the deck cleaner is suitable for the surface on that you intend to use it.



We live in an increasingly eco-aware world in that we are responsible for caring for our planet and ensuring a safe future for our families. Do your part by seeking out a deck cleaner that is biodegradable. These will not only be safer for you and your family to use, but they will also not have any negative impact on wildlife when they inevitably find their way into local waterways.
