Sodium hypochlorite is a chemical commonly used for cleaning and disinfecting outdoor surfaces, including patios. Here are the general steps for cleaning a patio using sodium hypochlorite:
- Prepare the area: Before you begin, remove any furniture or other items from the patio and sweep the surface to remove any loose debris.
- Dilute the sodium hypochlorite: Sodium hypochlorite is a strong chemical that can cause skin and eye irritation, so it's important to dilute it before use. Follow the manufacturer's instructions for dilution, which will typically involve mixing the sodium hypochlorite with water in a ratio of 1:10 to 1:50, depending on the concentration of the solution.
- Apply the solution: Use a garden sprayer or a watering can to apply the diluted sodium hypochlorite solution to the patio surface, working in sections if necessary. Be sure to wear protective gloves and eye protection when handling the solution.
- Let it sit: Allow the solution to sit on the patio surface for 10-15 minutes to allow it to penetrate and break down any dirt, algae, or other stains.
- Scrub the surface: Use a stiff-bristled brush or a pressure washer to scrub the surface of the patio, working in a back-and-forth motion to loosen and remove any dirt or stains. Be careful not to damage the surface of the patio with too much pressure.
- Rinse the patio: Once the entire patio has been scrubbed, rinse it thoroughly with clean water using a hose or pressure washer. Be sure to rinse away all traces of the sodium hypochlorite solution.
- Allow the patio to dry: Allow the patio to air dry completely before replacing any furniture or other items.
It's important to note that sodium hypochlorite can be corrosive to some types of surfaces, so be sure to test the solution on a small, inconspicuous area of the patio before applying it to the entire surface. Additionally, be sure to follow all safety precautions when handling the solution, including wearing protective clothing and avoiding contact with skin and eyes.
