GOJO Industries is expanding.  The maker of Purell hand sanitizer, which has a campus in Wooster is now finalizing a deal to lease a warehouse in Massillon.  The approximately 430,000-square-foot warehouse will operate as a shipping and storage center for the Akron-based company.  The public demand for hand sanitizer has risen sharply since the coronavirus outbreak began, resulting in the company to seek out opportunities to expand.
