Why Choose Prestone Concentrated?

Extreme Weather Protection: Developed to handle the harshest environments, Providing freeze protection down to -18°C when used neat.
Advanced Cleaning Power: Effortlessly removes dirt, grime, bird droppings, and difficult traffic film that standard washes leave behind.
Streak-Free Technology: Specially formulated to prevent smearing, ensuring your vision remains unobstructed even in low-sun or night-driving conditions.
Safe for your Vehicle: Non-corrosive formula that is safe for all paintwork, plastics, and rubber seals. It also helps prevent "wiper chatter" by lubricating the blades.

Dilution:

Because this is a concentrated formula one bottle makes up to 25 litres.
