Vinyl siding is very popular due to its durability and simple maintenance. Dirt and insect secretion stains, however, can adhere to vinyl siding, attracting molds, mildews and algae. Insect stains and other debris can be removed by simply cleaning vinyl siding with household cleaners. Cleaning vinyl siding not only improves the appearance of the siding, but also allows the siding to last longer. Remove the unsightly insect stains from your vinyl siding by using simple cleaning techniques.
Cover all plants, shrubs and flowers with plastic sheets to prevent the cleaning solutions from damaging them. Close the windows and doors, and turn off the power to any outside electrical units.
Rinse the siding with a garden hose equipped with a nozzle. Set the nozzle on a medium misting spray, and then point the nozzle down when spraying the siding. This will prevent water from seeping behind the siding and causing damage to the wood sheathing behind it.
Pour 4 gallons of warm water into a large bucket, and mix in 1/4 cup of laundry detergent. Dip a soft brush into the soapy solution, and begin scrubbing the bottom of the siding using side-to-side motions.
Rinse the area you just cleaned with the garden hose, and then work your way up the siding. You may need to stand on a ladder to clean areas too high to reach.
Continue scrubbing the siding, focusing especially on the insect stains. Once the insect stains are removed, rinse the siding and allow the siding to air dry.
