Carbon Collective Hyper Hydrophobic Screen Wash — A screen wash concentrate that removes road grime and adds water repellency to the windscreen. It is intended for the washer reservoir, rather than direct application as a separate ceramic coating.

Manufacturer doses are for a 5 l reservoir: 120 ml initially, then 60 ml with water to fill. The winter dose of 120 ml is rated only to −5 °C. Use appropriately rated fluid for colder conditions and scale doses to reservoir volume.
