Exterior Paint Cleaning
Cover light fixtures and plants that are close to the exterior with plastic bags.
Connect a garden hose to an outside water faucet.
Connect a brush attachment to an extension pole, and attach the extension pole to the garden hose.
Combine 1/4 cup of trisodium phosphate (TSP) with 1 gallon of water for heavy duty cleaning.
Apply the TSP mixture onto the brush, and turn on the garden hose. Open the shutoff valve on the extension pole if applicable.
Start at the bottom of the exterior, and work your way up one section at a time. If you start at the top of the wall, the dirty water will streak; but if the dirty water runs down a clean surface, it will not streak.
Rinse the mixture off the exterior in a downward motion.
Mix one part bleach to three parts water to remove mildew stains.
Apply the bleach mixture to the mildew stains, and leave it for 20 minutes.
Rinse the exterior thoroughly.
