Oils and grease are insoluble in cold water. When you use a standard cold-water pressure washer on a greasy driveway or parking stall, the water pressure simply breaks the oil droplets into smaller pieces and scatters them across the surface, without actually releasing them from the concrete pores. Our industrial pressure washing units heat water to 200°F (93°C). At this temperature, the heat melts the grease and reduces the viscosity of motor oils, allowing our biodegradable alkaline detergents to surround and emulsify the petroleum. We discuss the thermodynamics of oil stain extraction and how hot water rotary scrubbers deliver a clean, stripe-free finish on concrete plazas.
Key Technical Takeaways
When selecting professional property services, it pays to ask detailed questions about the chemistry, safety protocols, and equipment being deployed. High-pressure washing is not a one-size-fits-all solution; brick, stucco, wood, and concrete all have different pressure thresholds. Similarly, modern sanitizing is built on safe biocides that target bacteria without off-gassing harmful pollutants.
