    Top 10 Composite Deck Cleaner – Editor’s Pick:

    A Buyer’s Guide To The Best Composite Deck Cleaner

    Before we go into the reviews, you’d need to know about deck cleaners and what to look for before purchasing one. There are hundreds of brands offering lucrative features but you should look for some specific things; we have explained them below for your convenience.

    • Surface Compatibility

    The first thing you need to look for in a deck cleaner is whether it’s suitable for your deck or not. If your deck is made of timber, you need to be pickier as wood tends to get damaged by abrasives.

    In that sense, always check the label before buying it. You can find out what kind of surface the deck cleaner should be used on its label.

    • Versatility

    Most people don’t use their deck cleaners on just the porch. Usually, you can use them for washing the driveway, car, and siding. Hence, look for the products that are suitable for paving, vinyl, rubber, or metal; that way you will be able to use one product on many things.

    • Ideal for Your Equipment

    Every deck cleaner is suitable for different equipment. Some cleaners work with pressure washers and others can be used with a mop. If you have a pressure washer, we recommend you look for cleaners that are compatible with it. Many products can be used with a mop so you can opt for them as well.

    • Cleaners with Oxygen Bleach

    Oxygenated deck cleaners tend to be more popular these days. The reason is that these products are more environment-friendly and also efficient. Besides, Sodium Percarbonate is better for your deck as well.

    • Biodegradable Product

    Decks have plants around them and they are often close to plant-beds or lawns. If you live in the countryside, chances are you are often visited by wild animals. This is why you need to use a biodegradable product on your deck.

    However, most cleaners available in the market are biodegradable so you won’t have trouble finding one. Just look out for it.

    • Texture

    Deck cleaners can be granular or liquid; so opt for the one you’re comfortable using. If you don’t have enough storage space, we recommend going for the granular one. Just mix it with water before use.

    • Efficient

    The cleaners you are using should clean-up molds, hazardous substances, stench, algae, and other stuff that’s making the deck slippery. If the product isn’t doing these, you’re just throwing your money away. Therefore, make sure you purchase a strong and efficient deck cleaner for effective cleaning.

    7. Wash Safe Industries WS-SC-1G Clear Spray and Clean Composite Deck Cleaner

    If your deck is porous, most composite deck cleaners must not work on your deck, but this one will for sure. This particular cleaner is designed to be effective on any porous surface and reaches deep into particles to clean them from the inside.

    Mold and mildew would grow again if they’re not completely cleaned. So use this cleaner for your porous surface to clean it effectively.

    On the other hand, the cleaner isn’t completely free of bleach, but it contains chlorine bleach in a moderate amount (only 5%). As the chlorine works on the deck’s porous surface, you don’t need to scrub the surface after applying this formula.

    However, cleaning your deck for the first time? You will need to follow some steps for doing that. Chances are the cleaner won’t reach deep into your deck and won’t be able to wipe out all of the dirt. So mold stains will keep reaching to the surface and you’ll need to clean them once or twice.

    After the initial cleaning phase, you can clean your deck only once a month with a spray gun using this cleaner. Also, if you apply the formula 1-2 hours early of rain, you don’t even have to rinse it.

    Pros

    • 1 gallon covers 250 sq. ft. 
    • Very powerful
    • Works on a porous surface
    • Contains 5% Chlorine bleach
    • Safe to use

    Cons

    • Cannot be diluted
    • Not environment-friendly

    8. Simple Green Oxy Solve Deck and Fence Pressure Washer Cleaner

    The cleaner is designed for heavy-duty usage. You can use it to clean fences, decks and other structures like gazebos, pergolas, and carports. If you’re purchasing a deck for only your home, you don’t need to buy this one as it’s more appropriate for professionals.

    Besides, this formula can work on almost anything; it removes grime, oils, grease, stains, mold, algae, mildew, mud, clay, and moss. As the cleaner uses peroxide for removing grime, no harm is done to plants.

    1 gallon of this cleaner can clean an area of 6,400 sq. ft. This is enough for most users. If you want more products, you can always go for the larger containers.

    As the product is heavy-duty, it does contain some chemicals. So whenever you are using it around plants, be careful not to spray it directly on the plants. This might cause the plants to die very quickly.

    Pros

    • Professional grade
    • Can work on gazebos
    • Uses peroxide
    • Removes oil
    • 1-gallon container

    Cons

    10. Deck Wood Cleaner – 2.25 lbs – Makes 5 Gallons of Wood Deck Cleaning Solution

    Specially designed for wood decks, this cleaner opens the wood pores of your deck and applies oxygenated bleach to clean out the pores. Deep cleaning is very important for wood as molding may cause rotting to them.

    Frequently Asked Questions

    Q. Is it important that my deck cleaners are oxygenated?

    Answer: If you have a lawn and plants around your deck, yes, an oxygenated deck cleaner ensures the safety of your plants all the while cleaning your decks.

    Q. Are chlorine deck cleaners more powerful?

    Answer: Not necessarily. Both chemical and biodegradable deck cleaners can be powerful and effective if you’re using them right. Chlorine cleaners tend to do the job faster because the chemical is more aggressive than natural products.

    Q. Why does hydrogen peroxide turn foamy when applied?

    Answer: Hydrogen peroxide or oxygen bleach creates a foamy layer to remove algae, mold, and mildew from your deck. The substance reacts with the surface elements and turns foamy.

    Q. Do natural deck cleaners kill algae?

    Answer: No, the natural cleaners simply remove algae from your deck so that you can rinse them off. But they don’t necessarily kill anything because that requires the product to have harmful chemicals in it.

    Q. Can I use instant or 30-second cleaners if I have plants or a lawn?

    Answer: Yes, you can. But you need to rinse the plants with water for 10-20 minutes so that the cleaner is removed from the plants.

    Final Verdict

    Not many of us have a deck and if somebody has it, they should definitely take good care of it. If you use any of the products we have reviewed here, you can clean your deck comfortably and keep it free from the mold for years without issues.

    However, check the surface of your deck before you pick the best composite deck cleaner. As most cleaners can be used on other surfaces too, you might as well check what else you want to clean with this purchase. Natural or not, be careful while using the cleaner as bleach damages clothing.
