The Hospeco 12x12 300GSM Microfiber Cloth is designed for maximum absorbency and long service life. Made from 80% polyester and 20% polyamide, split fibers lift and hold dust, dirt, and liquid for fewer passes. The thick pile absorbs spills quickly and leaves surfaces streak free in wet or dry use. Reusable and machine washable, supports color-coded systems to reduce cross-contamination. Blue color for windows and hallways.
