The EcoClean® wiper is composed of U.S.-sourced cotton fibers and is manufactured by a proprietary process for low fiber release and high levels of strength. Unlike a traditional cotton twill wiper, EcoClean® features low ionic traces and low fibers release. EcoClean® 35 is offered in a quarter-folded format.
