The Brawny Professional H700 Cleaning Towel System Refill is part of the Brawny Professional Cleaning Towel System. Because the towels are made from hydro-entangled fiber (HEF), they’re strong, tear-resistant—and can handle everything from fluid spills and grease to industrial cleaners and solvents. They’re also reusable, cloth-like and disposable when soiled or contaminated. Plus, they’re absorbent and low lint. These towels are a safer alternative to rental shop towels, which can contain metal shards.
