It is a liquid concentrate which is added to caustic soda or to made-alkaline detergents increases cleaning efficiency. It binds the ions causing water hardness, and accelerates the release of existing precipiations. It increases the speed and efficiency of cleaning, therefore the amount of alkaline can be siginficantly reduced compared to the usage without the additive. It spares the construction materials, on the other hand it facilitates the handling of wastewater.
