Being in spray form, it's simple to apply, making it convenient for users who prefer a hassle-free cleaning process. This cleaner is particularly beneficial for those looking for an eco-friendly option, as its organic ingredients minimize environmental impact.

The effectiveness of the cleaner may vary depending on the level of dirt and staining on the deck, meaning some users might need to apply it more than once for optimal results. The 1-gallon volume should cover a significant area, making it practical for larger decks. Despite weighing 9 pounds, the product's ease of use compensates for its heft. This deck cleaner would be ideal for homeowners looking for a straightforward and environmentally conscious solution to keep their composite decks clean and well-maintained.

The Simple Green Oxy Solve Deck and Fence Pressure Washer Cleaner is a versatile cleaning solution designed for various outdoor structures including decks, fences, pergolas, gazebos, and carports. It utilizes the power of peroxide to effectively lift away tough grime, oils, grease, and even tree sap without the use of harsh chemicals, making it a safer choice for the environment. This cleaner comes in a liquid form, is unscented, and is packaged in a 128 fl. oz. bottle.

One of its significant strengths is its coverage; a single bottle can clean up to 6,400 square feet, which is quite impressive for large cleaning tasks. Additionally, the product is biodegradable, which means it is environmentally friendly and won't cause harm to surrounding plants or soil. It is a pressure washer concentrate, meaning it needs to be used with a pressure washer for optimal results, which might be a limitation for users who do not own one.

Another advantage is its ease of use; simply connect it to your pressure washer and start cleaning. However, its effectiveness might vary depending on the intensity of the stains and the type of surface. The lack of a scent can be a positive for those sensitive to strong smells. In conclusion, this cleaner is a solid choice for those needing to maintain large outdoor areas, offering powerful cleaning capabilities with an environmentally friendly formula, though it does require a pressure washer for use.

The DEFY 2 LB Wood Deck Cleaner Powdered Concentrate is designed to clean a variety of surfaces including decks, fences, and sidings. One of its major strengths is its effectiveness in deep cleaning and preparing wood surfaces for staining. This is achieved through its oxygenated bleach formula, which not only removes dirt but also opens up the wood pores for better stain absorption.

The product is capable of removing the graying effect caused by UV rays and mill scale from new wood, making it versatile for both old and new wood surfaces. An added benefit is its safety around grass and most plants, meaning you won't have to worry about damaging your garden while you clean your deck. Its recyclable materials also make it a somewhat environmentally friendly option.

On the downside, the product comes as a powder concentrate, which means you have to mix it with water before use; this might be less convenient compared to ready-to-use solutions. However, one pack covers a large area of up to 1,000 square feet, providing good value for its price. If you're looking for a versatile and effective cleaner for wood and other surfaces, this product could be a solid choice, provided you're okay with the extra step of mixing the concentrate.
