The GARDENA Shampoo was specially developed for the Original GARDENA Cleansystem. Through the circular shape, you can directly add it to the dispenser of the Original GARDENA Cleansystem Running Water Handles (Art. No. 5552-20, 5550-20, 5554-20).Through the rotary knob on the Running Water Handle, the Shampoo can be easily and precisely dosaged. Especially paint- and plastic surfaces are gently and effectively cleaned. The Shampoo is biodegradable.
