Yes. We use biodegradable, professional-grade cleaning solutions designed for exterior use, and we wet down landscaping before, during, and after to dilute any runoff. We’ll also let you know if we need pets kept inside during the job. Our mixes are built from sodium hypochlorite, surfactants, degreasers, oxalic acid, and sodium metasilicate — and it’s all about the right ratios, not just mixing them and hoping something works.
