If you’re a home owner its important to know how to soft wash a house. Rough weather can leave streaks on vinyl siding, windows, and other parts of your home, making it look shabby and dirty. Fortunately, soft washing can solve these problems. Learn how to soft wash a house below.

What is Soft Washing?

Soft washing is a cleaning process used by professional pressure washers for house washing purposes. This cleaning method involves using a low pressure stream of water while pressure washing and using various cleaning solutions to clean the exterior surfaces of a house.

You don’t have to be a professional house washing aficionado nor a pressure washing professional to soft wash your home. Soft washing is actually quite simple once you learn how.

Benefits of Soft Washing

Soft washing your home offers many benefits. The main benefit is a clean house. But here are some other soft washing benefits you should know about.

Soft washing benefits:

  • Uses less water (better for the environment)
  • Gets rid of harmful black mold (black mold growth can make you sick and kill you)
  • Stop mildew growth and prevent mildew spores from spreading (mildew can cause cosmetic damage to your entire home)
  • Get rid of spider webs and prevent pest infestation (spiders and insects can harm you and your home)
  • Remove chemicals and contaminants (chemicals and contaminants from the atmosphere end up invisibly causing damage to your home and your health)
  • Clean off grime and dust, and remove dirt and other debris from the exterior of your house (dirt and grime makes your home look aged and causes vinyl siding to become weak, warped, and damaged, eventually causing structural damage to your home)
  • Prevent roof damage (roof shingles age much faster if not kept clean, and a new roof can be as expensive as purchasing a new home)

Final Tips For Light Pressure Washing

It is important to do light pressure washing (soft washing) with a low PSI pressure washer. Every pressure washer is different.

You want one that is safe enough to clean wood paneling, your roof, vinyl siding, and really any surface safely. It also needs to handle the best concentration of chemicals (e.g., a higher concentration of bleach and cleaners).

The worst mistake you can make is to be in a hurry. This is when you make mistakes. Take your time and do a good job.
