Pro Tips

  • **Surface Assessment**: Always assess surface condition and contamination level before starting to determine appropriate pressure and chemicals.
  • **Safety First**: Use proper PPE including eye protection, non-slip footwear, and protective clothing when power washing.
  • **Environmental Protection**: Contain runoff and use eco-friendly chemicals when possible to protect landscaping and water sources.
  • **Pressure Selection**: Start with lower pressure and increase as needed - too much pressure can damage surfaces.
  • **Pre-Treatment**: Apply cleaning chemicals and allow dwell time before pressure washing for better results.
  • **Equipment Maintenance**: Regularly maintain equipment for optimal performance and safety.
  • **Weather Considerations**: Avoid power washing in freezing temperatures or high winds for safety and effectiveness.
