When you get a soft wash, your wood fence is sprayed, but never with a PSI over 1,000.
This is less than half of the PSI used for pressure washing. Making use of dwell time and letting the surfactants sit for the proper time, soft washes don’t rely on pressure, but instead on soaps and detergents!
For many, it may not be clear what the difference is between pressure washing and soft washing. The two are similar in that both use pressurized water to effectively clean grime and growths from your wood fence. However, soft washing is the ideal cleaning method for the wood surfaces. Soft washing uses a combination of low-pressure water spray and chemical surfactants to destroy dirt, mold, and algae buildup. With this method, the chemicals do most of the work so that high pressure isn’t necessary. Your exteriors get a thorough clean with no damage involved.
