Introduction
Keeping the exterior of your home clean is not only aesthetically pleasing but also essential for its longevity and value. Over time, dirt, grime, mold, and other contaminants can accumulate on various surfaces such as siding, bricks, concrete, hardi plank, wood, and shingles. Fortunately, pressure washing and soft washing techniques provide effective solutions to restore the cleanliness and beauty of these surfaces. In this comprehensive guide, we will explore the best practices and recommended methods for pressure washing and soft washing different types of exteriors.
Table of Contents
1. Understanding Pressure Washing and Soft Washing
Pressure washing and soft washing are two powerful techniques used to clean and restore various exterior surfaces. Pressure washing utilizes high-pressure water to remove dirt, grime, and other contaminants from surfaces, while soft washing employs low-pressure water combined with specialized cleaning solutions to achieve similar results with less force.
Both methods can effectively clean siding, bricks, concrete, hardi plank, wood, and shingles, but it's essential to understand the specific requirements and precautions for each surface.
2. Pressure Washing vs. Soft Washing
Pressure washing is generally suitable for robust surfaces such as concrete and bricks, where high-pressure water can effectively remove tough stains and dirt. However, pressure washing can be too aggressive for more delicate surfaces like wood and shingles, potentially causing damage.
On the other hand, soft washing is a gentler approach that is ideal for siding, wood, and shingles. By using low-pressure water and specialized cleaning solutions, soft washing can effectively remove contaminants without the risk of damage.
3. Preparing for Pressure Washing
Before starting any pressure washing or soft washing project, it's crucial to prepare the area properly. Here are some essential steps to follow:
Clear the area: Remove any objects, furniture, or plants that could obstruct the cleaning process or be damaged by the water pressure.
Wet surrounding plants: If you have nearby plants or landscaping, thoroughly wet them with plain water before starting to minimize the impact of any cleaning chemicals.
Test the pressure: Adjust the pressure washer to the appropriate setting for the surface you are cleaning. Start with a lower pressure and gradually increase if needed, taking care not to exceed the recommended limits for the material.
Protect yourself: Wear protective clothing, including goggles, gloves, and appropriate footwear, to avoid any injuries or exposure to chemicals.
4. Pressure Washing Siding
Siding is a popular exterior material that requires periodic cleaning to maintain its appearance. Pressure washing can effectively remove dirt, dust, oil, grease, and mold from siding surfaces. However, it's essential to follow the recommended techniques to prevent damage.
4.1 Cleaning Dirt and Dust
To clean dirt and dust from siding, follow these steps:
Use a soft brush or cloth: Avoid using hard metal brushes or abrasive sponges as they can damage the siding's finish.
Wet the surface: Wet the siding with a garden hose before brushing to loosen any dirt particles.
Brush the siding: Gently brush the siding's surface in a side-to-side motion, following the direction of the plank, shingle, or panel siding.
Rinse with water: After brushing, rinse the area with clean water using the garden hose.
Pro tip: Work from top to bottom, working on small sections at a time, to prevent dripping or streaking onto the cleaned area.
4.2 Removing Oil and Grease
If your siding has oil or grease stains, follow these steps for effective cleaning:
Use a soft cloth: Grab a soft cloth and saturate it with a mixture of mild liquid dishwashing soap and water.
Clean the stained siding: Gently clean the stained area with the soapy cloth, rinsing it frequently.
Rinse with water: Once the siding is clean, use a garden hose to thoroughly rinse the area.
Pro tip: Avoid allowing soap or cleaners to dry on the siding. Continuously rinse the area until all soap has washed off.
4.3 Eliminating Mold and Mildew
To remove mold and mildew from siding, follow these steps:
Inspect the siding: Carefully examine the siding for any signs of mold or mildew, which can resemble dirt.
Use a soft cloth or sponge: If mold or mildew is present, use a soft cloth or sponge to lightly scrub the affected area.
Apply a mildew-specific cleaner: Apply a mildew-specific cleaner according to the instructions provided, taking care to follow all precautions.
Rinse with water: After scrubbing, rinse the area thoroughly with a garden hose.
Pro tip: Be cautious when using stronger chemicals for cleaning siding, as they can potentially damage the siding's finish. Always read the instructions and use caution.
5. Pressure Washing Bricks
Bricks are a durable and versatile exterior material that can accumulate dirt and stains over time. Pressure washing is an effective method for cleaning bricks, but it's important to follow the proper techniques to avoid damage.
5.1 Removing Dirt and Stains
To clean dirt and stains from bricks using a pressure washer, follow these steps:
Wet the bricks: Before starting, wet the bricks with a garden hose to prevent the detergent from drying too quickly.

Allow the detergent to sit: Let the detergent sit on the bricks for the recommended time, typically 5-10 minutes.
Pressure wash the bricks: Using a pressure washer with the appropriate nozzle, apply even pressure to the bricks, working from top to bottom and overlapping each pass.
Rinse with water: After pressure washing, thoroughly rinse the bricks with clean water using the garden hose.
5.2 Treating Efflorescence
Efflorescence is a white, powdery substance that can appear on brick surfaces. To treat efflorescence, follow these steps:
Wet the bricks: Wet the bricks with water before applying any cleaning solution.
Apply a efflorescence cleaner: Use an efflorescence cleaner specifically designed for bricks. Apply the cleaner according to the manufacturer's instructions.
Scrub the bricks: Use a soft brush or sponge to gently scrub the affected areas, focusing on the efflorescence stains.
Rinse with water: After scrubbing, rinse the bricks thoroughly with clean water using a garden hose.
Pro tip: Efflorescence may require multiple treatments for complete removal. Be patient and repeat the process as necessary.
6. Pressure Washing Concrete
Concrete surfaces, such as driveways, sidewalks, and patios, can accumulate dirt, grime, and stains over time. Pressure washing is an effective method for cleaning concrete, restoring its original appearance.

Pressure wash the concrete: Using a pressure washer with the appropriate nozzle, apply even pressure to the concrete surface, working in sections and overlapping each pass.
Rinse with water: After pressure washing, rinse the concrete surface thoroughly with clean water using the garden hose.
6.2 Removing Tough Stains
For stubborn stains on concrete surfaces, follow these additional steps:
Identify the stain type: Determine the type of stain (oil, grease, rust, etc.) to choose the appropriate stain remover.
Apply the stain remover: Apply the stain remover to the affected area according to the manufacturer's instructions.
Scrub the stain: Use a stiff brush to scrub the stain, applying pressure as needed to break up the stain.
Rinse with water: After scrubbing, rinse the area thoroughly with clean water using the garden hose.
Pro tip: For particularly stubborn stains, you may need to repeat the process or use specialized stain removers.
7. Pressure Washing Hardi Plank
Hardi Plank, also known as fiber cement siding, is a popular choice for its durability and low maintenance. Pressure washing can effectively clean Hardi Plank siding, but it's crucial to follow the recommended techniques to avoid damage.
