Frequently Asked Questions
Will this cleaner prepare my deck well enough for a new stain to look even?
Yes. Removing grime, sap, and old weathering is the critical first step before staining, and the peroxide formula lifts contaminants without raising the wood grain the way bleach can.
Can I use it to restore the natural color of weathered cedar fencing?
It will clean away the gray organic buildup on cedar, revealing the natural wood tones underneath. For deep sun-fading, follow with an oxalic acid brightener before staining.
Will it help a gazebo look newer before guests arrive for an outdoor event?
A thorough pressure wash with this cleaner removes the dust, pollen, and mildew that make outdoor structures look tired, giving an immediate visual lift for entertaining.
Does it strip old sealer or stain, or do I need a separate stripper?
It is designed to clean, not to strip. If you are removing an old failing stain or sealer, plan on a dedicated stripping product before using this cleaner.
Will the wood look refreshed enough that I can skip restaining this year?
A deep clean can dramatically improve appearance, but it does not replace the protective layer that stain or sealer provides. Cleaning is best done as prep for refinishing.
Is this the right product to brighten a fence before listing my home for sale?
Yes. A clean fence signals good maintenance to buyers and instantly improves curb appeal. This gallon covers up to 6,400 sq ft, enough for most residential fences.
Can I use it to prep a pergola for a clear matte sealer?
Absolutely. Removing all surface contaminants is essential before applying a clear sealer, and the colorless formula will not interfere with the final finish tone.
Will it change the color of my redwood deck?
The cleaner itself is colorless to pale straw and will not add tone. It removes buildup that can dull redwood, so the result is a more natural, vibrant wood color.
How does it compare to renting a sander for refinishing my deck?
Sanding removes wood fiber along with the old finish, which thins your deck boards over time. Cleaning with this product preserves the wood while still preparing it for restain.
Is it better than a vinegar and water DIY wash for curb appeal projects?
Vinegar works on light mildew but cannot break down tree sap, grease, or heavy grime. This concentrate is purpose-built for the stains that actually age outdoor wood.
Will the wood look blotchy if I only clean half the deck?
Yes, you will see a clear line between cleaned and uncleaned sections. Plan to clean the entire surface in one session for an even, refreshed appearance.
What if the wood looks dull after cleaning but before I seal it?
That is normal. Cleaning exposes raw wood fibers that have lost their luster. The sealer or stain applied afterward is what restores the rich, finished look.
Can I use this on a painted fence without ruining the paint?
It is intended for bare wood. On painted surfaces, test a small hidden area first, as the peroxide and citric acid can dull or streak certain paint finishes.
How do I use this cleaner with a pressure washer step by step?
Connect your pressure washer, fill the detergent reservoir or attach the siphon tube to the concentrate, apply evenly to a pre-wet wood surface, allow 5 to 10 minutes of dwell time without letting it dry, then rinse with the pressure washer at low to medium pressure working with the wood grain.
What dilution ratio should I mix for general deck cleaning?
For most pressure washers with downstream injectors, the product is used as a concentrate at full strength through the siphon. For hand pump sprayers, a common ratio is 1 part cleaner to 10 parts water. Always check the bottle label for the most current mixing instructions.
Should I wet the plants and grass around my deck before I start?
Yes. Pre-wet all surrounding landscaping with fresh water, cover delicate plants if possible, and rinse them again immediately after you finish to wash away any overspray or runoff.
Will this work with any brand of pressure washer?
It is compatible with most electric and gas pressure washers that have a detergent feed system, including common consumer brands like Sun Joe, Ryobi, Karcher, Simpson, and Generac.
Can I use it in a pump sprayer instead of a pressure washer?
It can be applied with a pump sprayer, though it is optimized for pressure washer use. Expect to scrub lightly and use more product per square foot compared to machine application.
What is in the box when I order this product?
You receive one 128 fl oz (1 gallon) container of Simple Green Oxy Solve Deck and Fence Pressure Washer Cleaner. No additional sprayers, hoses, or accessories are included.
Is the formula safe if it gets on my skin or in my eyes?
As with any cleaner, wear gloves and eye protection. If contact occurs, rinse the affected area with plenty of water. The peroxide and citric acid formula is far milder than bleach, but basic protective gear is still recommended.
How should I store the gallon between uses?
Store the container sealed in a cool, dry place out of direct sunlight. Keep it away from children and pets, and do not allow the liquid to freeze, as this can reduce effectiveness.
What is the difference between a deck cleaner and a deck stain or sealer?
A deck cleaner like this product removes dirt, grime, sap, and organic stains from the wood surface. A stain or sealer is applied afterward to add color and protect the wood from UV and moisture. Cleaning is a required prep step before refinishing.
