Uncap the bottle and place the button, with the built-in swivel cannula, on the outlet pipe of the dosing valve. The application is carried out directly by pressing the valve and directing the solution outlet to the area to be treated with the cannula. It is recommended to rinse the cannula with water, dry it and store it after use. Spray 3 or 4 times on the surface to be treated, 2 or 3 times a day.
