Hot steam only uses water and sometimes a natural, mild cleaner to disinfect surfaces, so you don’t need any harsh chemicals to achieve a spotless environment free of stains, germs and viruses. You’ll be able to clean a variety of items without damaging the environment. When cleaning with chemical cleaners, the toxins can leach into the local soil and water supply, poisoning plants and animals. The fewer chemicals you use, the kinder you are to the environment.
