When in doubt about a surface, always spot test first.
PRESSURE WASHER APPLICATION
Use caution when using a pressure washer around openings like windows, doors, and plumbing connections. Protect nearby plants and grass by rinsing them with water before and after pressure washing.
- Hose down the surface.
- Pour full-strength Simple Green House and Siding Cleaner into your pressure washer detergent tank, or drop your siphon tube into the bottle of Simple Green.
- Apply Simple Green onto siding in sections from bottom to top, using a low-pressure setting and a 25-40 degree nozzle tip. Make sure your pressure washer nozzle is pointed at the siding in a downward angle, keeping a minimum of 18 inches from the surface to avoid driving water beneath or behind the siding. Do not allow the product to dry onto the surface.
- Rinse well with clean water from top to bottom.
- In a bucket or large container, mix 1.5 cups Simple Green House and Siding Cleaner in a gallon of water.
- Hose down the siding.
- Use a soft-bristle brush to apply the cleaning mixture in sections, scrubbing firmly enough to clean without damaging the siding surface. Don’t allow to dry between sections.
- Rinse with hose.
Be sure to check your warranty beforehand. Always follow the manufacturer's recommendation on proper cleaning practices.
