3 Criteria to Look For Before Buying a Deck and Fence Cleaners (2026)
Key buying criteria so you get the right fit the first time.
Wood-Safe vs. Composite-Safe
A cleaner that is fine on pressure-treated pine can cloud or streak a composite board, and a composite formula may not shift grey off bare timber well. Check the label names your decking type. DeckMax is composite-rated; Oxy Solve Total covers both.
If you have Trex or TimberTech, do not use a generic wood wash on it.
Peroxide vs. Bleach Chemistry
Sodium hypochlorite (bleach) cleaners act fast but can lighten wood, corrode fasteners, and kill plants at the base of a fence. Peroxide-based cleaners like Oxy Solve are slower but far gentler on timber and run-off.
Before staining a deck, peroxide is the safer prep; avoid bleach on wood you plan to seal.
Flat Deck vs. Vertical Fence
A thin liquid works well flooded across a flat deck but runs straight off a fence. A foaming cleaner like Microban clings to vertical surfaces. If your job is mostly fencing, the applicator format matters as much as the chemistry.
Match the product form to the plane you are cleaning.

Frequently Asked Questions
Can I use the same cleaner on my deck and my fence?
Usually yes, if it is a wood-rated cleaner, though a thin liquid runs off a vertical fence and a foaming product like Microban clings better. The bigger question is your decking material: a composite board needs a composite-rated cleaner even if the fence is timber.
Is bleach bad for a wood deck?
Sodium hypochlorite cleaners can lighten the wood, weaken surface fibers, and corrode screws and nails, and they harm plants at the base of a fence. If you are going to stain or seal the wood afterward, a peroxide-based cleaner like Simple Green Oxy Solve is the safer prep.
Do I need to clean a deck before staining it?
Yes. Stain will not bond properly over grey weathered fibers, mildew, or ground-in dirt, so it peels early. A deck cleaner strips that layer back to sound wood. Let the deck dry fully, usually a couple of days, before applying stain or sealer.
How much deck cleaner do I need?
Measure the deck area plus both sides of any fence. Concentrates like the Zep wash and Simple Green Oxy Solve cover thousands of square feet after dilution; the DeckMax kit covers about 1,500. Buy for the total area with a margin for a second pass on bad spots.
