Hospeco SmartRags 12in x 12in microfiber cloths are built from 200 GSM, 80% polyester/20% polyamide microfiber that lifts dirt, grease, and heavy soils for a streak-free, lint-free finish on glass, equipment, and general surfaces. Seamless, heat-sealed edges resist fraying, and the color-coded yellow helps prevent cross-contamination between areas. Reusable and launderable hundreds of times, they ship 50 per box in a center-pull dispenser.
