Frequently Asked Questions About Pressure Washing

What are the different types of pressure washer nozzles?

Pressure washer nozzles come in various spray patterns and angles, each designed for specific cleaning tasks:

• 0-degree Nozzle: Produces a highly concentrated, powerful jet of water for removing stubborn stains or stripping paint. Use with caution as it can damage surfaces easily.
• 15-degree Nozzle: A versatile nozzle for cleaning concrete, brick, and other hard surfaces. Provides a good balance of pressure and coverage.
• 25-degree Nozzle: A wider spray pattern for cleaning delicate surfaces like siding or fences.
• 40-degree Nozzle: A very wide spray pattern, ideal for rinsing or applying cleaning solutions.
• Soap Nozzle: A low-pressure nozzle designed specifically for applying cleaning solutions.
• Rotary Nozzle: Also known as a turbo nozzle, it produces a rotating, high-impact spray for tackling tough stains and grime.

Choose the appropriate nozzle based on the cleaning task and the type of surface being cleaned. Consult the pressure washer manual or a professional pressure washer for guidance.

Can pressure washing remove mold and mildew?

Yes, pressure washing can effectively remove mold and mildew from various surfaces, but the appropriate cleaning method depends on the surface type and severity of the growth:

• Pressure Washing: For hard surfaces like concrete, brick, or decks, pressure washing can effectively remove mold and mildew. Use a cleaning solution containing bleach or mildewcide for optimal results.
• Soft Washing: For delicate surfaces like roofs or siding, soft washing is the preferred method for mold and mildew removal. Soft washing uses low-pressure water and specialized cleaning solutions to gently remove mold and mildew without damaging the surface.
• Prevention: After cleaning, take steps to prevent future mold and mildew growth by addressing moisture issues, such as fixing leaks, improving ventilation, and trimming vegetation that creates shade and traps moisture.

If you have extensive or persistent mold and mildew problems, consult with a professional pressure washing company or a mold remediation specialist.

How do I know if I need pressure washing or soft washing?

Choosing between pressure washing and soft washing depends on the surface being cleaned and its condition:

• Pressure Washing: Suitable for hard surfaces like concrete, brick, stone, and decks that can withstand high pressure. Effective for removing stubborn dirt, grime, and stains.
• Soft Washing: Best for delicate surfaces like roofs, siding, painted surfaces, and wood fences that may be damaged by high pressure. Effective for removing mold, mildew, algae, and other contaminants without causing harm.

If you're unsure which method is best for your surfaces, consult with a professional pressure washing company. They can assess your needs and recommend the most appropriate cleaning method.
