This Sodium Hypochlorite 14/15% Patio Cleaner is designed for homeowners and professional landscapers looking to restore outdoor surfaces by eliminating stubborn moss, algae, and weed growth. Its high-concentration formula acts as a powerful disinfectant, delivering a deep clean that often requires only a single application to see significant results. While highly effective at cleaning driveways, patios, and brickwork, it is a potent chemical compound that requires careful handling, protective gear, and caution to avoid damaging surrounding vegetation or sensitive surfaces.

Yes, it is highly effective on block paving, concrete, and brickwork.
No. Keep pets away from the treated area until the solution has been fully rinsed away and the surface is dry.
Typically, you should allow the solution to dwell until you see the moss or algae changing color, usually within 15-30 minutes, before rinsing.
Sodium hypochlorite is an oxidizer primarily for organic matter; it is not specifically formulated to remove mineral or metal-based rust stains.
In many cases, the chemical action does the heavy lifting, but light brushing can help loosen stubborn growth before a final rinse.
Ensure the surface is dry before application and check if the dilution ratio is appropriate for the severity of the growth.
Pre-wet surrounding plants with fresh water before application and rinse them thoroughly if any overspray occurs.
Ensure the cap is tightly sealed after every use and store the drum in an upright position in a secondary containment tray.
To ensure safety and performance, always store the drum in a cool, dry, and well-ventilated area, away from direct sunlight and out of reach of children or pets. When preparing to use the product, ensure you are wearing rubber gloves, eye protection, and protective clothing to prevent skin contact. Before widespread application, perform a patch test on an inconspicuous area of the surface to check for any unexpected discoloration. After use, rinse all application equipment thoroughly with clean water to prevent corrosion or chemical residue buildup. Do not mix this product with other chemicals, especially acidic cleaners, as this may release hazardous gases.
