A homemade cleaning mixture, often involving bleach or sodium hypochlorite, surfactants, and water, prepared by individuals for the purpose of gently removing organic growth and stains from exterior surfaces. These mixtures are typically applied using low-pressure equipment to prevent damage to delicate siding, roofing materials, and other vulnerable areas.
The appeal lies in the potential for cost savings and control over chemical concentrations, allowing homeowners to tailor solutions to specific cleaning needs and environmental concerns. Historically, individuals relied on simpler cleaning methods, but the increasing awareness of the damaging effects of high-pressure washing on certain surfaces has led to the adoption of this gentler, chemically-driven approach for maintaining property aesthetics and preventing premature degradation of building materials.
