Don’t skip deck cleaning.
Imagine this scenario. You’ve decided to clean your deck. In your head, you’re thinking:
Man, these greedy companies always create products I don’t need.
You’d be right if you were talking about something like a cordless jump rope. But deck cleaner is not a gimmick — but you skip it because you think it’s unnecessary and do a quick pass with a pressure washer before you stain, and (as the days pass) a huge mildew stain rears its head.
You can’t always see what’s underneath when you’re cleaning. A deck cleaner gets deep into the grain and pulls out all the mold, algae, and mildew that get inside the wood. I’m going to share 5 of my favorite deck cleaners with you, but — trying not to belabor the point here — let’s talk a little bit more about the importance of deck cleaners first.
The Importance of Deck Cleaners
Mother Nature throws rain, snow, and sun at your deck with a vengeance. If you don’t clean it, it’ll start looking bad. Mold and grime look bad. They’ll ruin your deck in no time.
Deck cleaners lift out all those contaminants so that when you stain and seal your deck, no unsightly spots make their way to the surface. If that does happen, you’re in a world of hurt.
You have to strip back the seal and the stain to wash it out. And guess what you’ll be using? A deck cleaner. So, you might as well use a deck cleaner and save yourself the time and the effort.
Here’s the deal: deck cleaning isn’t something to take lightly. Regularly maintaining your deck ensures your financial investment remains protected. It means keeping your outdoor space you enjoy spending time in. Choose a cleaning product that can eliminate persistent stains while maintaining your deck’s excellent appearance.
Consistent deck maintenance remains the most effective way to keep your deck in top condition. You can enjoy the deck outdoors for many years by caring for it properly. If you ignore maintenance your deck will need expensive replacement work.
Okay, you get the point. Here are my 5 favorite deck cleaners.
5 Best Deck Cleaners of 2025
These are 5 of the best deck cleaners I’ve come across. Our company is all about composite, so some of these are newer and not ones I’ve had the chance to test. That said, I took a look at the product descriptions and reviews, and I asked some other deck pros their thoughts. These five came up the most:
Star Brite Non-Skid Deck Cleaner & Protectant
The Star Brite Non-Skid Deck Cleaner & Protectant can transform how you maintain your deck’s appearance. It’s got exceptional cleaning abilities. It effortlessly removes dirt and mildew from a textured surface while eliminating algae growth.
One of the reasons homeowners consider Star Brite one of the best deck cleaners of 2025 is that it’s not rough on paint.
The absence of any slippery residue makes this product a favorite among homeowners since it focuses on safety. The product works to improve the non-skid surface while maintaining its intended texture. Another bonus? The protective barrier it leaves prevents grime from accumulating at a faster rate. You’ll spend less time cleaning because of the long-term effects.
Olympic Exterior Deck Cleaner
The Olympic Exterior Deck Cleaner is an excellent product for people who want to bring back their deck’s natural beauty. This product successfully removes tough dirt, stains, mildew, and algae, which makes it perfect for restoring heavily weathered wood surfaces.
One homeowner wrote:
“This product does a decent job of getting rid of all the junk. What I like best is that it’s ready to go. No mixing needed.”
The cleaner is applied directly onto your deck and sits for a few minutes before beginning to dissolve dirt. After a brief rinse, the surface will appear refreshed and bright. No scrubbing is needed — that’s impressive.
The product demonstrates both high effectiveness and wide-ranging versatility. Deck preparation before staining or sealing becomes easier for many users because this product helps achieve an even application throughout the surface.
It’s easy. It’s cost-effective.
M-1 1-Gallon Deck Cleaner for Wood and Concrete
The M-1 1-Gallon Deck Cleaner is tough. I’ve heard from a few of my buddies that it does a good and thorough job.
It’s highly effective at cleaning wooden and concrete surfaces. The cleaner battles tough stains. Mildew? No issue. Sianara mold.
This cleaner stands out because it can reach deep into porous materials to remove dirt without the need for heavy scrubbing. This deck cleaner stands out as the preferred choice for readying decks, patios, and driveways before sealing or staining because it delivers a uniform, professional appearance.
Because the M-1 Deck Cleaner is biodegradable, it won’t run off into a drain and cause environmental issues. It’s also nontoxic. That’s my favorite part: your kids and your pets can get out after application without having to worry too much about it (but store deck cleaners away from them and follow all instructions).
Users find the product’s rapid action highly beneficial. Apply it. Wait. Rinse. Its reasonable price matches its capacity to clean extensive areas with just one gallon. The M-1 Deck Cleaner stands out as one of the best deck cleaners of 2025.
Cabot 128-fl oz Deck Cleaner
The Cabot 128-fl oz Deck Cleaner stands out as a reliable choice for cleaning and restoring decks. The product’s heavy-duty formula cleans weathered wood surfaces by removing mildew, algae, and dirt, leaving the surface fresh and ready for staining or sealing.
Cabot stands out for its exceptional ability to brighten wood surfaces and rejuvenate older decks. This deck cleaner requires no mixing because it comes pre-prepared for immediate use — you only need to apply it, wait for it to absorb, and rinse it off.
DIY homeowners who prepare their decks for staining favor Cabot Deck Cleaner. The cleaner removes surface contaminants and old finishes to ensure stains bond smoothly across the surface for a sleek appearance. The cleaner protects surrounding plants from damage, eliminating concerns about plant harm during cleaning.
The Cabot 128-fl oz Deck Cleaner is great for restoring your deck’s natural beauty while saving time on scrubbing for regular upkeep and thorough cleaning tasks.
BEHR PREMIUM 1 gal. All-In-One Wood and Deck Cleaner
The All-In-One Deck Cleaner by BEHR provides a perfect solution to restore your deck’s appearance. From everyday messes like a glass of wine getting knocked over to deeper issues like mold, it can do the job well.
I added this to my list of the best deck cleaners of 2025 because it works beyond surface cleaning by penetrating deeply to bring back your wood’s original color and give it a refreshed appearance.
Several customers described the cleaner’s effectiveness through their shared experiences. One user even noted that it broke down some moss growing on the deck’s side.
The application is straightforward. The cleaner works on stubborn stains at full strength, while lighter cleaning requires a diluted solution. Use a pump sprayer, brush, mop, or roller to apply the solution, then wait 10-15 minutes before scrubbing with a stiff-bristle broom or brush. After that, rinse thoroughly with water.
Quick Summary
I get it — deck maintenance can seem like a daunting task. But here’s what you need to remember from everything we’ve covered: deck cleaners serve a necessary purpose. They’re not a scam. My list of the 5 best deck cleaners of 2025 is the real deal. They’ll protect your deck.
All five products provide unique advantages that benefit your deck. Star Brite stands out through its non-skid protection, while Olympic simplifies cleaning with its no-scrub formula, and M-1 provides an eco-friendly deep clean solution.
The bottom line? Don’t skip deck cleaning. These cleaners work well against daily dirt buildup and persistent mold growth to maintain your deck’s appearance and prolong its lifespan. Proper cleaning requires some initial investment. True. But you’ll spend a lot more trying to strip back sealant and stain if you skip a clean.
