1. Remove cap and insert bottle upright into device until it 'clicks' (keep embossing on bottle facing front).
2. Push device onto one of the blades of the car vent in an upright position to avoid spills. Do not push in between blades of vent.
3. Max 45 degrees. To avoid spills, do not use on tilted blades, and never turn upside down.
Wipe away any spilt product immediately with water as it may cause damage and ensure no residue remains.
