Angelwax Clarity is a super concentrated screenwash, made in Scotland, for the washer reservoir of any vehicle. One bottle covers the whole year: Angelwax recommends 19:1 water to Clarity in summer, 9:1 in spring and autumn, 4:1 in winter at around -5°C and 1:1 in severe winter at around -13°C, and it can be used neat as a de-icer in extreme conditions. It is formulated to remove insects, bird droppings, traffic film and road grime, and leaves a subtle hydrophobic effect that helps water clear from the glass. Pair it with a dedicated glass cleaner for the inside of the screen and fresh wiper blades. The 1L suits most drivers, while the 5L makes sense for vans, fleets and multi-car households.
