Frequently Asked Questions About Pressure Washing

What is the difference between pressure washing and soft washing?

Pressure washing and soft washing are two distinct cleaning methods, each suited for different surfaces and cleaning needs.

Pressure washing uses high-pressure water spray to blast away dirt, grime, and other stubborn contaminants from hard surfaces. It's effective for cleaning driveways, decks, patios, fences, and siding.

Soft washing utilizes low-pressure water combined with specialized cleaning solutions to gently remove dirt, mold, mildew, and algae from delicate surfaces like roofs, siding, and painted surfaces. Soft washing is less abrasive than pressure washing, preventing damage to sensitive materials.

Choosing the appropriate cleaning method depends on the type of surface, its condition, and the desired cleaning outcome. Consult with a professional pressure washing company to determine the best approach for your specific needs.

What are some common pressure washing mistakes to avoid?

Pressure washing, when done improperly, can lead to damage or unsatisfactory results. Here are some common mistakes to avoid:

• Using Excessive Pressure: High-pressure water spray can damage delicate surfaces like wood siding or painted surfaces.
• Using the Wrong Nozzle: Different nozzles produce different spray patterns and pressure levels. Using the wrong nozzle can cause streaks, uneven cleaning, or damage.
• Holding the Nozzle Too Close to the Surface: Holding the nozzle too close can etch or damage the surface. Maintain a safe distance as recommended by the pressure washer manufacturer.
• Skipping Pre-Treatment: For stubborn stains or mold growth, pre-treating the surface with a cleaning solution can enhance cleaning effectiveness.
• Not Protecting Plants and Landscaping: Pressure washing chemicals and debris can harm plants and landscaping. Cover or shield sensitive areas before pressure washing.

If you're unsure about pressure washing techniques or the appropriate pressure levels for your surfaces, consult with a professional pressure washing company.

Can pressure washing damage my plants?

Yes, pressure washing can damage plants and landscaping if not done carefully. The high pressure and harsh chemicals in cleaning solutions can harm or kill plants:

• Cover or Shield Plants: Before pressure washing, cover or shield delicate plants and landscaping with tarps, plastic sheeting, or painter's tape to protect them from water spray and chemicals.
• Use Lower Pressure Settings: If pressure washing near plants, use lower pressure settings and avoid directing the spray directly at them.
• Rinse Plants with Water: After pressure washing, rinse plants thoroughly with plain water to dilute any chemicals that may have landed on them.
• Choose Plant-Safe Cleaning Solutions: If using cleaning solutions, opt for environmentally friendly or plant-safe options whenever possible.

Taking these precautions minimizes the risk of damage to your plants and landscaping during pressure washing.

• Safety Precautions: 'What safety precautions do you take during pressure washing?'
• Surface Preparation: 'Will you need to move any furniture or objects before pressure washing?'
• Water Usage: 'Do you use a water reclamation system or other methods to conserve water?'
• Cleanup: 'How do you handle cleanup after pressure washing?'
