To pressure wash house mildew, mix a mildewcide solution with water. Apply to affected areas. Let sit for 10-15 minutes. Use a low-pressure setting to rinse off the solution, working from top to bottom. Avoid high pressure to prevent damage.
Preparing to Pressure Wash Your House
Assessing the Extent of Mildew Presence on House Exteriors
Before you begin the cleaning process, it is crucial to evaluate the severity of the mildew problem.
Look around all areas of your home’s exterior, paying special attention to shaded spots and those with less air circulation, as these are prime areas for mildew growth.
Document the areas that require treatment and plan your cleaning route accordingly. This step ensures that you do not miss any spots during the pressure washing process.
Choosing the Right Pressure Washer and Safety Equipment
Selecting the appropriate pressure washer is vital for effective cleaning and safety. A machine with adjustable pressure settings is ideal.
You should also acquire safety equipment, such as goggles and gloves, to protect yourself from any flying debris and chemicals.
Make sure you understand how to operate your pressure washer by reading the manual or watching instructional videos.
Preparing the Cleaning Solution for Mildew Removal
To tackle the mildew, create a mixture of a mildewcide solution and water following the manufacturer’s instructions.
This solution will help break down and kill the mildew, making it easier to remove. Ensure that you mix the solution in a well-ventilated area and use a container appropriate for the amount you need.
Protecting Plants, Outdoor Furniture, and Electrical Outlets
Before starting the pressure wash, cover or move plants, outdoor furniture, and any other items that might be damaged by the water or cleaning solution.
Use plastic sheeting or tarps for protection. Make sure to cover electrical outlets to prevent water from getting in and posing a hazard.
Wetting Surrounding Areas to Prevent Cleaning Solution Absorption
It’s important to dampen the surrounding areas, including plants and grass, that are not being cleaned to prevent them from absorbing the cleaning solution.
A simple garden hose will work for this purpose. The water creates a barrier that helps to dilute any solution that comes into contact with these areas, protecting them from potential damage.
The Pressure Washing Process
Starting from the Top
When pressure washing your house, always start from the top and work your way down. This method ensures that the dirty water flows down and doesn’t dirty the cleaned areas.
Begin with the gutters and eaves, gradually moving down to the siding and foundation. Use a ladder safely to reach higher areas.
Adjusting Pressure Settings and Selecting the Proper Nozzle
Adjust the pressure washer to a low or medium setting to prevent damage to your siding, especially if it’s made of a softer material like wood or vinyl.
Choose a nozzle that provides a wide angle for a broad, gentle spray. Nozzles are usually color-coded, so refer to your pressure washer’s guide to select the right one.
Applying the Cleaning Solution to Affected Areas
Once the pressure washer is set up, apply the cleaning solution to the areas affected by mildew.
Use a low-pressure setting to spray the solution evenly, ensuring that all the mildew spots are covered. Allow the solution to penetrate the mildew to break it down effectively.
Importance of Letting the Solution Sit for the Right Amount of Time
After applying the solution, it is important to let it sit for about 10-15 minutes. This dwell time allows the mildewcide to work its magic.
However, ensure that the solution doesn’t dry on the surface, as this can cause streaking. Keep the surface wet if necessary, especially on sunny days.
Rinsing the Solution Off Thoroughly and Systematically
Once the solution has had time to sit, begin rinsing it off from the top down. Use a steady, sweeping motion to rinse off the solution and mildew.
Be thorough but gentle to prevent any damage. Make sure to rinse off all the solution to avoid any residues that could attract dirt or quickly lead to mildew returning.
Post-Pressure Washing Care and Maintenance
Inspecting the House for Any Missed Spots of Mildew
After pressure washing, inspect your house for any spots of mildew that might have been missed. Look at different angles and in different lighting conditions to make sure you catch any remaining mildew.
This is also the time to check for any potential damage that might have occurred during the process.
Touching Up Areas That Need Additional Cleaning by Hand if Necessary
If you find areas that have stubborn mildew stains, you may need to do some additional cleaning by hand.
Use a soft brush and the same cleaning solution to gently scrub these areas. Rinse them off with a garden hose to remove any loose mildew and cleaning solution.
Recommendations for Preventing Future Mildew Growth
Preventing future mildew growth involves regular maintenance and taking proactive measures.
Trim trees and bushes to increase sunlight and air flow around your house. Consider using mold-resistant paint or additives the next time you paint your home. Regularly clean gutters and downspouts to prevent water accumulation.
Tips for Regular Maintenance and When to Schedule the Next Pressure Wash
For ongoing maintenance, inspect your home annually and clean any mildew as soon as you spot it.
Plan to pressure wash your house every two to three years, or more frequently if you live in a humid climate or have had mildew problems in the past. Keeping up with these maintenance tasks will help keep your home looking its best and protect it from damage.
