How to Clean Stucco Siding
Stucco has been in use for hundreds of years, and is increasingly popular as an exterior finish for homes. Although stucco is easy to clean, delicate care should be taken to remove dirt buildup within its porous, textured surfaces. Follow these basic maintenance steps to keep the best look and longest lifespan for your siding.
- In a bucket or large container, mix 1.5 cups Simple Green All-Purpose 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.
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 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.
