Close the cover and hold a jerry can (min.10 litre capacity ) under the tap. Turn the tap open. The polluted cleaning agent is now discharged from the tank into the jerry can. Close the tap. Remove the receptacle from the tank and pour ½ litre clean solvent into the tank. Clean the tank and the filter which is attached to the suction hose. Hold the jerry can under the drain tap, turn the tap on and clean the tank with the brush. Close the tap. Again fill the tank with clean solvent: the micro cleaner is now ready for re-use.
