Thank you for going the zero waste route! Pour the content of this bottle into any container and add 700ml water. You now have 750ml of strong, intelligent soap. You can reuse the bottle or give it to the courier next time we deliver, for us to fill again. Clean the really dirty areas such as braais, grills and ovens with MIGHTY. The millions of indigenous microbes in this bottle will release enzymes to break down tough dirt and digest bacteria that cause bad odours. After you have finished cleaning, some microbes will be left on the surface to keep watch against undesirables. Those microbes you pour down the drain will continue to remove nasties like nitrates, nitrites and ammonia from the waste water, the natural way. Everything in this bottle is non-toxic and degrades within 28 days. Even the colourant and fragrance are hypo-allergenic and natural so that you can rest assured you are doing no harm. Neither to yourself nor to the environment.
