Green cleaning very important some companies say you don’t just green it you clean it and by doing that it’s all about the chemicals the equipment and the processes all have to be green now that green cleaning is so big industry that if you’re using traditional products they’re usually cheaper quality and they don’t get the disinfecting that is required these days and so same thing on the equipment side you can buy cheaper products out but they’re not going to be green HEPA filtration systems and so we recommend everybody use a hundred percent green products equipment and chemicals.
