Recently, Don Cahill of Power Wash King shared some of the things that go into professional power washing—and there’s a lot more to it than just pointing a pressure washer at a dirty surface!
Don has been in the industry for 22 years, starting with window washing before recently focusing exclusively on power washing.
A few things we learned:
🧽 Different surfaces require different techniques—vinyl, aluminum, stucco, wood, brick and more all need to be cleaned differently.
🫧 Soft washing uses soap and chlorine to actually kill algae and organic growth rather than simply blasting it away with water.
🌿 Plants are carefully pre-wet before washing, then rinsed again afterward.
🧱 Brick can hold algae tightly, and some stains require scrubbing or specialized acids to lighten them.
⚠️ Knowing the right products, techniques and precautions for each surface is an important part of professional power washing.
💦 Don uses specialized equipment, including large machines capable of moving up to 10 gallons of water per minute, along with proper respiratory and skin protection.
🏠 And don't be surprised if a house wash turns into a whole-house cleaning! Once one area is cleaned, you may realize the rest of the house isn't quite as clean as it looked. 😄
Power Wash King handles a wide variety of residential and commercial cleaning projects, including house siding, sidewalks, patios, decks, fences, outdoor furniture, playsets and more.
🚿 Don is meticulous about his work, paying attention to every surface and angle—including getting into all the sides and details of fences that are easy to overlook.
It was a great look at the techniques, equipment and experience that make a difference between simply washing a surface and actually knowing how to clean it properly.
Have something outside your home or business that could use a good cleaning? It might be worth asking Don! Power Wash King provides residential and commercial power washing services throughout the area.
