Uncap the bottle and place the button, with the built-in adjustable cannula, on the outlet tube of the metering valve. The application is carried out directly by pressing the valve and directing the solution outlet with the cannula toward the area to be treated. 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.
