WHAT-A-METHOD® is WE Group's proprietary post-PFAS cleaning protocol that follows a precise five-step process — remove excess soiling, water rinse and blot, apply a water-based cleaner and blot, water extract, then finish with a solvent-based cleaner and extract — ensuring complete stain removal from the inside out. This systematic approach eliminates the need for toxic fluorochemicals while outperforming legacy PFAS-based methods, giving facilities a fully compliant, science-backed cleaning solution that leaves surfaces restored and residue-free.
