The Norwex antibacterial Microfiber EnviroCloth™ removes dust, dirt and grease from all washable surfaces using only water—no chemicals! Our superabsorbent EnviroCloth picks up dust particles and traps them in the cloth until you rinse it out. Then BacLock™* in the cloth—our micro silver antibacterial agent—goes to work to self-purify and inhibit bacterial odors, mold and mildew growth within the cloth.
