Difference of Pressure Washing Compared to Soft Washing
Pressure Washing by definition means using a high pressure stream of water usually 1000 Psi to 4500 Psi to rinse off dirt, debris and organics. It can be used on many surfaces to remove any tough layers of debris. Best for cleaning concrete, pavers, bricks and painted surfaces.
To achieve the high pressure needed to clean professional power washing companies use high powered pressure cleaning machines usually gas powered with the correct nozzles, hoses and surface cleaners. The machine is fed water usually by a garden hose into the pump where it is sucked in and pressurized to shoot out through a steel braided hose.
Approximately 90% of the cleaning is done here (we will clarify as we continue)
Instead of changing the speed on your pressure washing machines is is safer and easier to change pressure by switching nozzle attachments.
Soft Washing by definition is using chemicals and soaps (surfactants) to remove and kill mold and mildew from surfaces, typically roofs, house siding and walls, soft wood, pvc fences, exterior gutters and many more surfaces. Main chemicals used are liquid chlorine and surfactant that is bleach stable. The chlorine is primarily composed of salt that kills mold and mildew from surfaces without any damage. The bleach stable surfactant helps keep the chlorine wet and sticky to the surface. The keep here is plant and property protection. (Please review our other posts for property protection).
Soft Washing is all bio-degradable and uses safe chemicals for cleaning, leaving a long lasting clean.
We highly recommend using a combination of both when cleaning most surfaces to protect from any damage. For example when cleaning a concrete driveway it is recommended to pressure wash 90% of the grime that is layered on with high water pressure and high pressure rinse off, next apply the right concentration of soft washing chemical to kill any removing mold or mildew to get the best results while not harming any landscape.
