10 Best Deck Cleaners 2025 in the United States

The Simple Green Industrial Cleaner and Degreaser offers a powerful solution for cleaning decks, given its industrial strength and ability to remove heavy dirt, grease, and stains. Its concentrated formula is cost-effective, allowing for custom dilution according to the cleaning task at hand, which can be particularly useful for various deck cleaning needs. The cleaner is biodegradable and recognized by the U.S. EPA's Safer Choice Program, which means it has a lower environmental impact compared to harsher chemicals, making it a safer choice for outdoor use around plants and wildlife. Additionally, it has a pleasant sassafras scent which can help in deodorizing your deck area effectively.

Users can apply it manually or with various professional cleaning equipment, providing flexibility in terms of ease of use. However, the product is designed for various surfaces like counters, carpet, machines, and vehicles, which may raise questions about its specific compatibility with all types of deck materials. If your deck is made from delicate wood or composite materials, you may need to test the cleaner on a small area first to ensure it does not cause damage. Another consideration is safety; while it is safer for the environment, precautions should still be taken during use, especially if diluted inappropriately. The versatility of the cleaner means it can handle diverse cleaning tasks, but its suitability for deck-specific cleaning should be evaluated based on your deck's material and condition.

This makes it a good choice for people looking for a simple and quick cleaning solution without extra equipment.

It is compatible with many materials commonly found in outdoor spaces, including wood decks, vinyl siding, brick, concrete, and even plastic furniture. This versatility means it can handle multiple cleaning jobs around your home, not just decks. Another plus is its safety when used as directed; it won't harm your lawn, trees, or shrubs, which is important if you want to protect your garden while cleaning. However, the product does contain active ingredients and comes as a concentrated liquid, so careful following of instructions is necessary to avoid misuse.

While it is effective on organic stains, it may not be the best choice for heavy dirt buildup or tough stains that require scrubbing or pressure washing. Also, since it’s a chemical spray, users concerned about environmental impact should consider this factor, even though it claims to be plant safe. This cleaner is a solid pick for regular maintenance and light to moderate stain removal on a variety of deck and outdoor materials, especially if you want an easy, no-fuss method.
