One of the first things people notice when they pull up to your house is the siding. Vinyl siding becomes dirty and stained over time. Mold, mildew and algae are just a few of the causes of dirty vinyl siding. Cleaning vinyl siding will preserve the appearance of the exterior of your home. Bleach is commonly used to clean dirty siding and is especially effective at remove mold, mildew and algae from the surface.
Wet down surrounding plants and landscaping with plain water. Cover them with plastic sheeting for further protection. Bleach can cause damage to plants and landscaping.
Close all windows and doors to the home. Turn off the power to exterior electrical units. Remove outdoor furniture, toys and other items from the vicinity that may be damaged by the bleach. Cover exposed electrical outlets with duct tape.
Spray down the siding with plain water from the garden hose. Use a high-pressure nozzle on the garden hose to remove loose dirt and debris.
Fill a clean, empty garden sprayer with a chlorine bleach and water mixture. Use three parts warm water to one part bleach.
Work in 3- to 5-foot sections when cleaning. This will prevent the bleach mixture from drying onto the siding before rinsing.
Spray a generous amount of the bleach mixture onto the siding. Leave the solution on the siding for about five minutes.
Scrub the siding with a long-handled soft scrub brush. Start at the bottom of the house and work your way toward the top.
Rinse the siding with plain water from the garden hose. Repeat this process, working in 3- to 5-foot sections, until all of the siding has been cleaned. Avoid letting the bleach mixture dry onto the siding before rinsing.
Wear rubber gloves, protective eye wear and old clothing that covers your arms and legs when working with chlorine bleach.
