Steam can sanitize your mattress, and kill harmful viruses, bacteria, and bed bugs!* Attach the cylinder wand and cylinder cleaning cloth to your Nugeni steamer. Make sure to keep moving the steamer slowly over the mattress surface to avoid over saturating the bed, while steaming each section for 8-20 seconds. Allow the mattress a few hours to completely dry before replacing bed linens. *In controlled testing situations. Individual experience may slightly vary.
