Cleen Green was started to be the leading, environmentally friendly cleaning company. We chose to use upcycled, but of course sterilized, surgical towels, which are super absorbent, for cleaning rags, even though cheaper options were available. We also only use products that meet EPA Safer Choice®️ standard. Because to obtain the Safer Choice rating, a product must "meet strict safety criteria strict safety criteria for both human health and the environment, including carcinogenicity, reproductive/developmental toxicity, toxicity to aquatic life, and persistence in the environment." These products are not harmful to ourselves nor harmful to our environment.
