Power washing is using high pressure water to remove the dirt and grime from a surface. This could be anywhere from 1,300 up to 4,000 PSI (Pounds per Square Inch.) The only time you need that much PSI would be for hard surfaces. Those would be like cleaning concrete that is at least 3 years old, and sometimes bricks. High pressure should NEVER be used on vinyl siding or asphalt roofs. These should only be cleaned with Soft Washing. The high pressure adds lots of risks including blasting holes in your siding, blasting water behind your siding which could cause mold to start growing, or tearing your screens, just to name a few.
Soft Washing is a process using high volumes of low pressure water (500 PSI or less), high quality soap, and Sodium Hypochlorite (Bleach.) Don’t be afraid when you hear bleach. A Professional Washing Company will have it diluted down to a safe ratio. Soft Washing is a much safer and quicker cleaning method. The soap loosens the dirt and grime that has built up on your home’s exterior. The bleach kills the organic material on your house (mold, mildew, and algae). This process leaves a much cleaner finish than power washing. They might look similar, but power washing just blasts off visible build up leaving microscopic spores which will start spreading again. Soft washing kills organic build up even the the spores. It is like disinfecting your house. Thank you bleach! This will help prevent organic build up from coming back so quickly in the future.
Vinyl siding manufacturers even recommend to clean the vinyl siding with a mixture of soap, water, and sodium hypochlorite. Soft Washing should be the only cleaning process used when doing a House Wash or Roof Wash.
