Frequently Asked Questions
Will this concentrate hold up in an open-air pressure washer setup exposed to sun and wind?
Yes. Simple Green Oxy Solve Total Outdoor Pressure Washer Cleaner is formulated specifically for outdoor use. It mixes readily with water in your pressure washer tank, foams actively on contact, and rinses cleanly without leaving residue that attracts new dirt — even on exposed patios, decks, and driveways.
Can I use this cleaner on composite decking and still walk barefoot on it afterward?
Absolutely. The peroxide-based formula lifts mold, mildew, and algae from composite, wood, and concrete without leaving a chemical film. Once the surface is rinsed and dry, it's safe for bare feet, pets, and children.
Does the foam cling well enough to clean vertical outdoor surfaces like fences and siding?
Yes. The fast-acting foam is engineered to adhere to vertical and sloped surfaces, so you get dwell time on siding, fences, and outdoor furniture without constant reapplication or heavy scrubbing.
Will it damage my outdoor cushions, wicker furniture, or patio fabrics?
No. The formula is compatible with fabric, plastic, wicker, vinyl, and metal. It cleans grime and mildew stains without bleaching or weakening outdoor upholstery fibers when used as directed.
How much area can one gallon cover for a typical patio or driveway job?
One gallon of concentrate covers up to 6,400 square feet, so most homeowners can clean a full driveway, patio, and a section of walkway from a single bottle, depending on dilution and soil level.
Is this the right outdoor cleaner for prepping my deck before sealing or staining?
Yes, it's an excellent pre-stain prep. The peroxide action removes mildew, dirt, and grayed wood fibers so your stain or sealer adheres properly and lasts longer.
I'm restoring a weathered fence this weekend — is one bottle enough?
For most residential fences (roughly 200–400 linear feet), one gallon diluted into your pressure washer is typically sufficient. Heavily soiled fences may need a second pass at stronger concentration.
Will this work to clean algae off my boat dock and lakeside pier?
Yes. The biodegradable, non-toxic formula is safe for use near water when rinsed properly, and it removes the green algae and slime that build up on docks, piers, and lake platforms.
Can I use it on natural stone like flagstone or bluestone without etching?
Yes. Unlike acidic cleaners, Simple Green Oxy Solve is peroxide-based and won't etch natural stone, making it safe for flagstone, bluestone, limestone, and other delicate surfaces.
How is this different from a typical bleach-based outdoor deck cleaner?
Unlike bleach, this formula won't harm surrounding plants, won't fade wood fibers, and won't leave a lingering chlorine smell. It achieves similar brightening through peroxide power instead.
I usually rent a power washer once a year — is this easier than the bleach mixes I've used?
Yes. There's no mixing powders, no harsh fumes, and the Safer Choice certified formula is gentler on landscaping. You simply dilute, add to the pressure washer, and apply.
What if the algae on my patio is really black and stubborn — will peroxide actually cut it?
For heavy black algae, pre-wet the surface, apply at a stronger dilution, and let it dwell for 5–10 minutes before pressure rinsing. The peroxide penetrates organic growth and lifts it from porous surfaces.
Will it leave a chalky white residue on my dark composite deck?
No. The formula rinses clean and leaves no white residue, so it's safe for dark composite, stained wood, and colored concrete.
How do I use Simple Green Oxy Solve in my pressure washer?
For most pressure washers with a detergent tank, pour the concentrate directly into the onboard soap reservoir. For units with a siphon tube, attach the tube to the bottle. Apply at low pressure to wet the surface, let the foam dwell for 3–5 minutes, then rinse at high pressure. Adjust dilution based on soil level.
What dilution ratio should I use for heavy mold versus light dirt?
For light cleaning and maintenance, use a 1:10 to 1:20 dilution with water. For heavy mold, mildew, and algae, use a stronger 1:5 dilution or apply the concentrate directly through the pressure washer's soap nozzle for maximum strength.
Do I need to rinse the surface after applying the cleaner?
Yes. Always rinse thoroughly with clean water after the dwell time. For surfaces being prepped for staining or sealing, a final rinse is critical to remove all residue and allow proper adhesion.
Will this work with both electric and gas pressure washers?
Yes. It's compatible with all major consumer and light-commercial pressure washer brands, including electric, gas, hot, and cold water units, in the 1,500–4,000 PSI range.
Is it safe to use on painted surfaces?
Yes, on sound, properly bonded paint. It will clean dirt and mildew without stripping quality exterior paint. Avoid using on freshly painted surfaces (less than 30 days cured) or on failing/flaking paint.
What's included in the box when I order this product?
You receive one 1-gallon bottle of Simple Green Oxy Solve Total Outdoor Pressure Washer Cleaner concentrate. A pressure washer and hose are not included — these are sold separately or may already be part of your existing equipment.
Is this product safe if it gets on my skin or in my eyes?
While the formula is non-toxic and biodegradable, it is a cleaning concentrate and may cause mild irritation. We recommend wearing gloves and eye protection during application. If contact occurs, rinse thoroughly with clean water.
How should I store the bottle between uses?
Store the sealed bottle in a cool, dry place away from direct sunlight. Keep the cap tightly closed. The concentrate has a long shelf life and won't lose effectiveness when stored properly.
What's the difference between a pressure washer cleaner and a regular outdoor cleaner?
Pressure washer cleaners are specifically formulated to flow through pressure washer systems, foam properly, cling to vertical surfaces, and rinse cleanly without leaving residue. Regular outdoor cleaners often require hand-scrubbing and may not be compatible with pressure washer seals or injection systems.
