I have previously worked at a clinic doing janitorial work. Working there I realized that they don't use certain cleaning products that I am use to using on my previous jobs. The Health Department went green, that meant no use of bleach, almonia or other harmful and hazardous cleaning supplies.
As being introduced to the go green movement I learned that certain chemicals that patients encounter can trigger their sickness. Green products to my knowledge are odorless and made with natural products. The product I was familiar with was simple green, the product was great, real light odor and it cleansed well.
