WypAll X80 Extended Use Cloths feature innovations like high-tech HydroKnit fast-absorbing material and are durable for scrubbing. WypAll X80 are made of soft pulp fibers, bonded to a polypropylene base sheet for absorbency and durability, making them suitable for removing dirt, oil, grime and solvents in industrial and manufacturing businesses. These reusable cloths are reinforced for strength when wet and dry. Plus, they come in a convenient pop-up box (dispenses one at a time) and are so sturdy that they can often be used more than once (once you've used them a few times, they're disposable). These bulk cloths are a great alternative - safer and more efficient - to replace laundered rental shop towels and cleaning towels. Use them for heavy duty machine and part wiping, wiping metal shavings, prepping surfaces with solvents and cleaning rough surfaces. After all, every business gets dirty. But for the toughest grease and grime, you can trust Wypall X80 Cloths.
