Softwashing vs. Pressure Washing
One of the main differentiating factors of soft wash and pressure wash is one using high pressure and one using a lower pressure. Pressure washing or power washing uses high-pressure water that runs at a very high PSI. Meanwhile, softwashing uses much less power than that — more like a high powered hose.
Another difference is what comes out of the hose with soft washing vs pressure washing. While a pressure wash relies on the high-pressure water alone to clean properly, soft washing systems use a combination of cleaning solution and water to kill organic matter, such as mold and mildew to ensure your exterior stays clean for the long-term.
