TERRA GAIA Dishwasher Gel’s main active ingredient is made from horse chestnuts. Chestnuts, are high in saponin, a natural detergent and foaming agent. They developed a unique formulation of dishwashing gel that effectively removes dirt and grease from dishes and glasses, with the power of natural and non toxic ingredients. Put 15ml (2 black caps) of the product into the dishwasher tank. For a perfect washing result, we recommend using dishwasher salt and rinse aid.
