Absolutely. Our cleaning microfiber are in a three-step laundered to eliminate harmful pathogens. The first step we pre-soak the microfiber cloth in hot water and Lysol Laundry Sanitizer for at least 6-8hours (overnight). The second step is to rinse and load the washing machine, add laundry detergent and oxygen bleach. The machine is set at heavy duty, high heat and extra rinse cycle. Finally the load is dried at high heat. Note: We also color code our cleaning cloths. The blue microfiber is used only for cleaning kitchens. They are never mixed with other colored cloths. Not even after cleaned. If you have any concerns about sanitation of our materials, please don’t hesitate in asking for more information.
