From The Sacramento Bee: Custodians in the Elk Grove (Calif.) Unified School District went green before it was trendy. The district started using safer cleaners 10 years ago. Linda T. Lopez, the district's manager of custodial services, says district custodians use a hydrogen peroxide-based product to clean surfaces, and they strap on vacuum canisters outfitted with multiple high-efficiency particulate filters to suck up dirt and dust. The district's adherence to "green" cleaning puts it at a significant advantage if state Assembly Bill 821 passes. The Clean and Healthy Schools Act would require all K-12 schools with at least 50 students to switch to safer, environmentally friendly cleaning products if there are no additional costs to a district.
