I have two of these. The ONE microfiber cleaning cloth every healthy home should have. It cleans everything from dust to messes without using harmful chemicals. The densely woven, superfine Norwex Microfiber physically removes up to 99% of bacteria from a surface using only water when following proper care and use instructions. The EnviroCloth is the true all-purpose microfiber cloth you can’t do without. Pair it with our Cleaning Paste and there’s no stopping you! Reusable microfiber cloths are safer and better for you and for the environment. They help eliminate the use of paper towels and help prevent harmful chemicals in your home. Features BacLock®* antimicrobial agent which protects the cloth by winning the fight against odor-causing bacteria in the cloth, helping it to stay fresher longer. Size: 35 cm x 35 cm / 13.78″ × 13.78″ *BacLock is an antimicrobial agent solely intended to protect and self-clean the cloth by inhibiting growth of odor-causing bacteria, mold and mildew. BacLock does not protect people from disease-causing pathogens.
