Inspect the Exterior: Start by inspecting the exterior of your house for any damage or areas that may need special attention.
Gather Supplies: Gather all the necessary supplies including a pressure washer, chemical injector, sodium hypochlorite solution, surfactant, safety gear, ladder, and brushes.
Choose the Right Cleaning Solution: Mix sodium hypochlorite solution with water according to manufacturer’s instructions and add a surfactant to help the solution adhere to the mold.
Prep the Area: Remove any obstacles such as furniture, plants, or decorations from around the house.
Protect Nearby Plants: Cover nearby plants and shrubs with plastic sheeting to prevent damage from the cleaning solution.
Wet the Area: Use a hose to thoroughly wet down the area you’ll be cleaning.
Prepare Chemical Mixture: Pour the sodium hypochlorite solution mixed with water and surfactant into the chemical injector.
Start from the Bottom: Begin washing from the bottom of the house and work your way up to ensure that dirt and grime are effectively removed.
Use Low Pressure: Set the pressure washer to low pressure to avoid damaging the siding or paint.
Maintain Proper Distance: Keep the pressure washer nozzle at a safe distance from the surface to prevent damage and ensure even cleaning.
Apply Chemical Solution: Use the pressure washer with the chemical injector to apply the sodium hypochlorite solution to the surface, focusing on areas with mold or mildew.
Allow Chemical to Dwell: Allow the cleaning solution to dwell on the surface for a few minutes to effectively kill mold and mildew.
Scrub Stubborn Stains: For stubborn stains, use a brush or scrubbing pad to agitate the cleaning solution.
Rinse Thoroughly: After applying the cleaning solution, thoroughly rinse the house from top to bottom with clean water.
Pay Attention to Corners and Edges: Make sure to clean corners, edges, and other hard-to-reach areas where dirt and grime may accumulate.
Avoid Lingering on One Spot: Keep the pressure washer moving to prevent streaks or damage from concentrated pressure.
Be Careful with Windows and Doors: Use lower pressure and avoid spraying directly at windows and doors to prevent water from seeping inside.
Inspect for Missed Spots: After rinsing, inspect the entire house for any missed spots or areas that need additional cleaning.
Repeat if Necessary: If there are still stubborn stains remaining, repeat the cleaning process until the desired results are achieved.
Clean Gutters and Downspouts: While cleaning the exterior, take the opportunity to clean gutters and downspouts of debris.
Inspect for Damage: While cleaning, keep an eye out for any signs of damage such as cracks, loose siding, or peeling paint.
Make Repairs: If you notice any damage, make note of it and plan to make repairs once the house is dry.
Allow for Drying Time: Allow the house to dry completely before replacing any furniture or decorations.
Dispose of Waste Properly: Dispose of any leftover cleaning solution and waste materials properly according to local regulations.
Clean Up Equipment: Rinse out the pressure washer and cleaning equipment thoroughly after use to prevent damage and corrosion.
