What Do I Need to Soft Wash My House?

Maintaining a clean and well-kept exterior is essential for the longevity and curb appeal of your home. Soft washing is a highly effective method for removing dirt, algae, mold, and other contaminants without damaging your home's surfaces. This blog post will guide you through everything you need to know about soft washing, including the necessary equipment, chemicals, techniques, and safety measures. Whether you're a DIY enthusiast or considering hiring a professional, this comprehensive guide will provide valuable insights to help you achieve the best results.

What is Soft Washing?

Soft washing is a cleaning method that uses low-pressure water mixed with specialized cleaning solutions to safely remove organic stains, mold, mildew, and algae from exterior surfaces. Unlike pressure washing, which relies on high-pressure water to clean surfaces, soft washing uses a gentler approach that prevents damage to delicate materials like shingles, siding, and stucco.

Benefits of Soft Washing

• Gentle on Surfaces: Soft washing prevents damage to delicate materials that can occur with high-pressure washing.

• Effective Cleaning: The cleaning solutions used in soft washing break down contaminants at the molecular level, resulting in a thorough clean.

• Long-Lasting Results: Soft washing not only cleans but also kills the root of mold and algae, preventing quick regrowth.

• Environmentally Friendly: The biodegradable cleaning solutions used in soft washing are safer for plants and the environment.

Essential Equipment for Soft Washing

To achieve professional results, you'll need the right equipment. Here's a breakdown of the essential tools for soft washing:

Chemical Holding Tank

A chemical holding tank stores the cleaning solution before it's applied to the surfaces. These tanks are typically made of polyethylene or other chemical-resistant materials.

Recommendations:

• Size: For residential use, a 15-50 gallon tank is sufficient.

• Material: Polyethylene tanks are durable and resistant to chemicals.

Soft Wash Pump

The pump is the heart of the soft wash system, responsible for delivering the cleaning solution at low pressure. There are several types of pumps used in soft washing:

Types:

• 12V Diaphragm Pumps: Common in DIY setups, easy to use, and affordable.

• Booster Pumps: Provide higher flow rates and pressure, suitable for larger areas.

• Air Diaphragm Pumps: High efficiency and durability, ideal for commercial use.

Key Features:

• PSI (Pounds per Square Inch): Typically between 40-100 PSI for soft washing.

• GPM (Gallons per Minute): A flow rate of 4-6 GPM is ideal for effective coverage.

Hoses and Trigger Gun

The hoses and trigger gun are essential for directing the cleaning solution to the desired areas.

Hose Specifications:

• Length: 100-200 feet, depending on the size of the area being cleaned.

• Diameter: 1/2 inch for adequate flow.

• Material: Chemical-resistant materials like PVC or rubber.

Trigger Gun and Nozzles:

• Chemical-Resistant Components: Ensure longevity and safety.

• Variety of Nozzles: Different nozzles for varying spray patterns and applications.

Nozzles and Spray Tips

Nozzles and spray tips control the spray pattern and coverage of the cleaning solution.

Types:

• Fan Nozzles: Provide wide coverage, ideal for large areas.

• J-Rod Nozzle Holders: Allow quick swapping between different spray tips.

Application:

• Choosing the Right Nozzle: Match the nozzle to the surface and the level of dirt or contamination.

Proportioner or Mix Valve

A proportioner or mix valve helps accurately mix the cleaning solution with water.

Function:

• Accurate Mixing: Ensures the right concentration of chemicals for effective cleaning.

Options:

• Manual Proportioners: Simple and cost-effective.

• Automated Proportioners: Provide precise mixing ratios, ideal for consistent results.

Recommended Chemicals for Soft Washing

The effectiveness of soft washing largely depends on the cleaning solutions used. Here are some commonly used chemicals:

Primary Chemicals

• Sodium Hypochlorite: The primary agent for killing mold, mildew, and algae.

• Surfactants: Help the solution adhere to surfaces and improve cleaning efficiency.

Mixing Ratios

• Guidelines: Typically, a mix of 1 part sodium hypochlorite to 4 parts water, with added surfactant.

Supplemental Products

• Fresh Wash: Enhances cleaning power and helps remove stubborn stains.

• Biocides: Prevents regrowth of mold and algae.

DIY Soft Washing with a Pump-Up Sprayer

For smaller jobs or those on a budget, a pump-up sprayer can be an effective tool for soft washing.

Pump-Up Sprayer Overview

• Description: A handheld sprayer that uses manual pressure to apply the cleaning solution.

• Advantages: Cost-effective and easy to use for small areas.

Step-by-Step Guide

1. Preparation: Clean and fill the sprayer with the appropriate chemical mix.

2. Application Technique: Evenly spray the solution on the surface, ensuring full coverage.

3. Dwell Time and Rinsing: Allow the solution to sit for 10-15 minutes, then rinse thoroughly with water.

Setting Up Your Soft Wash System

Setting up your soft wash system involves assembling and connecting various components. Here’s how to do it:

Step-by-Step Guide

1. Assemble Components: Attach the pump to the chemical tank and connect the hoses.

2. Connecting Components: Ensure all connections are secure and leak-free.

3. Testing the System: Run the system with water first to check for leaks and proper operation.

Soft Washing Techniques

Proper technique is crucial for effective soft washing. Follow these steps for the best results:

Prepping the Area

• Safety Precautions: Cover plants, protect pets, and wear appropriate PPE.

• Initial Rinse: Pre-wet the area to prevent chemicals from absorbing too quickly.

Applying the Solution

• Technique: Apply the solution evenly, working from the bottom up to avoid streaks.

• Dwell Time: Allow the solution to sit for 10-15 minutes without drying out.

Rinsing

• Final Rinse: Use a low-pressure rinse to remove all traces of the cleaning solution.

• Inspecting the Cleaned Area: Check for missed spots or areas that need a second application.

Safety Measures

Safety is paramount when handling chemicals and equipment. Here are some important safety tips:

Personal Protective Equipment (PPE)

• Gloves: Chemical-resistant gloves to protect your hands.

• Goggles: Eye protection to prevent splashes.

• Respirators: Protect your lungs from chemical fumes.

Chemical Handling

• Safe Practices: Follow manufacturer instructions for mixing and storing chemicals.

• Spill Management: Have a plan for dealing with spills and accidental exposure.

Environmental Considerations

• Preventing Runoff: Use containment measures to prevent chemicals from entering waterways.

• Protecting Plants: Rinse plants before and after applying the cleaning solution to minimize damage.

Maintenance of Soft Washing Equipment

Regular maintenance of your soft washing equipment ensures longevity and efficiency.

Regular Cleaning

• Hoses and Nozzles: Rinse with clean water after each use to prevent clogging.

• Tanks and Pumps: Flush the system with clean water to remove any residual chemicals.

Routine Checks

• Inspecting Pumps and Hoses: Look for signs of wear and replace damaged parts.

• Checking Connections: Ensure all fittings are tight and leak-free.

Storage Tips

• Proper Storage: Store equipment in a cool, dry place away from direct sunlight.

• Winterization: For colder climates, winterize your equipment to prevent damage from freezing temperatures.

Conclusion

Soft washing is a highly effective method for maintaining the exterior of your home, offering a gentle yet thorough clean that extends the life of your surfaces. Whether you're using a professional soft wash system or a DIY pump-up sprayer, the right equipment, chemicals, and techniques are essential for achieving the best results. By following this comprehensive guide, you can ensure your home remains clean, beautiful, and free from harmful contaminants.
