This industry standard cotton dust mop is constructed from traditional long, stapled, tightly twisted virgin natural cotton yarn. Absorbent cotton yarn provides excellent dust retention for industrial and institutional applications. Great for schools, hospitals, and other health care facilities. The 5" x 24" white dust mop fits around our 24" quick change dust mop frame, which quickly connects to our quick change mop handle. For other options, please take a look at our complete line of dust mops. We recommend using our aerosol dust mop treatment for maximum dust retention.
