Bill Thompson, Director of Facilities for Lockport Township High School in Illinois, first considered starting a green cleaning program after his janitors became dizzy when using a traditional chemical floor stripper. Thompson started introducing green products gradually at Lockport Township High, and now almost all of the cleaning agents used at the school are environmentally friendly. The school has become a model for successful green cleaning program implementation and Thompson has worked to spread the word about green cleaning. Developing and implementing a green cleaning program does not have to be overwhelming or expensive. It is a process that can be accomplished in steps or phases, with positive results at each stage.
