No, we only use products that will not form harmful residues. Most companies will want to use a quaternary ammonium to act as a method to continue killing germs. The problem with this is they are sticky and can make future germ reservoirs. They are also easily absorbed through the skin and are known allergens, NIH 2014. Pathogend will never use harmful quats as a residue. Instead, we rely on silver if needed as a natural alternative to help prevent pathogens from making reservoirs in your space.  We offer both a non silver and/or silver based CURoxide (7% H202) when needed for each customers preference.
