DIY Family/Pet friendly cleaner! This little machine is worth it's weight in gold! It uses an ionization process on water mixed with a salt/vinegar concentration to make a household cleaner that kills a long list of germs and bacteria while being completely safe around kids and pets. The cleaner is only good 2 weeks after ionizing which is why you don't see it sold in stores. Force of nature is a portable machine to make this magic happen. I was skeptical when I first ordered mine but I am OBSESSED. I use it daily on every surface in home. I could not be happier with this product.
