Cleaners

The chemicals in cleaning products can be hazardous to maintenance workers and building occupants. These products can also be costly to store and dispose of. Products that are safer for human users are generally safer for the environment as well, and can replace more-toxic products.

Environmentally preferable cleaners may not be as readily available, but they are generally competitively priced. This includes the purchase price of the product, the cost of meeting regulations for worker safety and environmental rules, and the costs of disposal for leftover product.

To better safeguard the health of custodial workers, building occupants, and the environment, the state of Minnesota added environmental specifications to the state cleaning supplies contract.

Minnesota State Contract for Cleaning Products

When products were reviewed for the current state contract for cleaners, vendors were asked for the first time to include information about the environmental performance of their cleaning products. All products selected for the state contract — 33 categories of cleaning products, including all-purpose cleaners, cleaners for toilet bowls, furniture and glass, deodorizers, disinfectants, soaps and floor cleaners— were screened and rated for cleaning performance and environmental characteristics. This approach screened out many of the more harmful products, while still providing a variety of products from which to choose.

• The environmental review addressed human safety first. Vendors received higher points for avoiding product ingredients that are highly toxic, cancer-causing, flammable, or prone to cause skin irritation, respiratory problems or allergic reactions.

• The evaluation also addressed potential environmental impacts because chemicals in cleaning products end up in local wastewater systems, and eventually can pollute our rivers and lakes.

• Products received higher points for using plant-based ingredients because they are a renewable resource. Points were awarded for avoiding phosphates and substances that contribute to ozone depletion.

• Preference was given to products sold in reusable and/or recycled content packaging. A few points were also given to products not sold in aerosol containers because punctured or half-empty aerosols can increase flammability.

• Products with synthetic dyes and fragrances were avoided to limit potential allergic reactions or skin irritations.

Minnesota's Office Supply Connection: Greener cleaner available

The state's Office Supply Connection carries Spray & Clean, a pH-neutral, plant-derived, water-based cleaner. This less-toxic cleaner — one of the products on the state contract — replaces corrosive, caustic and butyl-based cleaners that can irritate lungs, skin and eyes.

As a spray-and-wipe cleaner, Spray & Clean can be used on desks, file cabinets, computer monitors, fax machines and copiers, walls, tile & grout, porcelain, stainless steel. laminates and any hard surface.

Spray & Clean is available in an 22 oz. ready-to-use spray bottle and a 64oz. refill size to save on packaging.

Restore Spray & Clean is made of plant-based surfactants, and includes no petroleum-derived ingredients, bleach, alcohol, ammonia, phosphates, or fuming solvents; as a result, it emits no noxious fumes or volatile organic chemicals (VOCs). The pH-neutral formula is designed to be safer for the user and the environment and can be safely disposed of in septic systems. Supplied by Restore Products, a division of Brown & Company, LLC (St. Paul, Minn.).

Success Story: City of St. Paul

"Overall, the non-toxic cleaners that we used in the last four months produced sparkling clean results and our custodial staff experienced fewer physical reactions when applying cleaning products," said Mark Galloway, building superintendent of the St. Paul City Hall Annex. "I'm particularly impressed with the performance of the new degreaser in removing deep stains and the furniture cleaner's effectiveness in repelling fingerprints and smudges from elevators and lobby furniture."

Responses similar to Galloway's were gathered in a pilot project that tested the performance of ten non-toxic cleaning products on typical office building surfaces such as glass, toilets, sinks, walls, floors, and furniture. Funded through a grant from the OEA, the Neighborhood Energy Consortium and the City of St. Paul organized this pilot in the spring of 1997.

The 65-year-old downtown St. Paul building served as an ideal location, with 17 floors, approximately 350 workers, and a link to the heavily traveled public skyway system. Under these conditions, products must perform well. The custodial staff of the city hall annex found that six of the ten alternative products worked as well as, or better than, the products they replaced. Moreover, custodial staff specifically noticed a reduction in the fumes that sometimes cause physical reactions such as lightheaded sensations and tightening of the chest. Overall, the non-toxic products were also priced comparably with the cleaners they replaced.

Restore the Earth (now known as Brown & Company) supplied the non-toxic cleaners for the pilot project. The cleaning products selected were derived from plant matter and renewable resources. They specifically avoided products containing hazardous chemical ingredients, chlorinated substances, phosphates, volatile organic compounds, and petroleum solvents or propellants. Products were also provided in refillable, reusable containers.

As a result of the pilot's success, the city hall annex custodial staff continued using most of the products tested.

Success Story: University of Minnesota

In fall 1999, the University of Minnesota's Facilities Management Division realized that empty and partly filled cleaning product containers were piling up in janitors' closets. With 11 million square feet being cleaned every day, the container pile-up was not just a logistical disposal problem — it was an employee health threat.

Environmental Health Specialist Clayton Handt and his colleagues set up a review board to do a top-to-bottom evaluation of the division's cleaners. The board discovered that Facilities Management was buying nearly 500 different products, many of which were redundant and contained chemicals listed on the U.S. EPA's Toxic Release Inventory (TRI).

After a thorough review, 70 percent of the division's inventory was eliminated. The board also agreed to switch to plant-based cleaners by 2005.
