For those really stubborn stains, in your bathroom or kitchen, that require special treatment once in a while, use this powerful natural descaling detergent. Made with natural origin organic acids (citric acid and lactic acid), it is recommended for the removal of limestone residues from polished surfaces, taps, stoneware, ceramics, and for the descaling of dishwashing machines. It contains natural origin raw materials (e.g. surfactants, acids) coming from the processing of glucose, corn, and potatoes. Phosphate and nickel-free (less than 0.01 ppm). Colourless and fragrance-free.
3% (300 ml in 10 L of water) for regular us or undiluted for really stubborn stains. The recommended dilution saves money and minimises environmental impact. If using undiluted, use sparingly.
