The Simple Green Oxy Solve Deck and Fence Pressure Washer Cleaner is a versatile and effective product for cleaning various outdoor structures, including decks, fences, pergolas, gazebos, and carports. One standout feature is its use of peroxide, which lifts grime, oils, and even tough stains like tree sap without relying on harsh chemicals. This makes it a great option for users concerned about the environmental impact, as it is biodegradable and free from harmful substances. The cleaner is unscented, which can be a plus for users sensitive to strong smells during application.

It is a liquid concentrate designed for use with a pressure washer, making it relatively easy to apply over large areas. With the ability to clean up to 6,400 square feet, it offers extensive coverage, which is suitable for larger decks or multiple outdoor structures. Users should note that it is a concentrate, so it requires proper dilution before use, which might be an extra step for some. The product's effectiveness can be influenced by the strength and settings of the pressure washer being used. Those without a pressure washer might find it less convenient.

This product is well-suited for users looking for an environmentally friendly and powerful solution to tough outdoor stains, particularly those who already own a pressure washer.

The DEFY 2 LB Wood Deck Cleaner Powdered Concentrate is a versatile and effective option for cleaning wood surfaces like decks, fences, and siding. One of its strong points is its ability to deeply clean and open the pores of wood thanks to its oxygenated bleach formula. This feature is particularly useful for preparing the surface before applying a stain. It’s also effective in removing the graying caused by UV rays on weathered wood, and it can clean new wood by removing mill scale, which can otherwise prevent stains from being absorbed evenly.

Users will appreciate that this cleaner is safe for grass and most plants, making it environmentally friendly for general outdoor use. Additionally, the product is biodegradable, further reducing its environmental impact. The powdered form makes it easy to store and use, and it can clean up to 1,000 square feet, which is a generous coverage area. While it’s mainly for wood surfaces, it also works on vinyl and aluminum siding, and even sidewalks and driveways, making it a good all-around household cleaner.

However, it's worth noting that as an unscented product, it may not mask odors that may be present on the surfaces being cleaned. This product is ideal for homeowners looking for a reliable and eco-friendly deck cleaner that can handle a variety of surfaces and stains.
