Our cleaning company is proposing to use a "Enviro Solutions - Neutral Disinfectant Concentrate #256". First, I'm not even sure which standard/certification (i.e. GS-37) I should be looking for. The reference guide is not clear about disinfectants. Second, if this doesn't meet the requirments, does anyone know of an alternative? Does anyone know which standards address "Disinfectants"?
