Anti-Fog Spray

The anti-fog formula works by creating a thin hydrophilic coating on the glass surface that causes water vapour to spread evenly across the glass as a transparent film rather than forming the tiny droplets that produce the characteristic opaque white fog. The practical effect is that glass treated with the spray does not fog when the temperature differential between the air and the glass surface is high — the conditions that typically cause fogging on a cold car windscreen in winter, on a bathroom mirror after a hot shower, or on a shower screen in a warm, humid bathroom. Without treatment, these droplets form because the glass is cooler than the surrounding air and causes water vapour to condense. The anti-fog coating interferes with this process and keeps the glass visually clear. A single application provides lasting protection, reducing or eliminating the need to wipe down the glass before use each day.

The waterproof coating creates a hydrophobic layer on the glass surface that causes water to bead into droplets and run off rather than spreading into a film. On a car windscreen or side window, this means rain water beads and clears from the glass surface more readily, improving visibility in wet driving conditions. At higher speeds, the airflow over the car assists the water in clearing from the glass, which can reduce the frequency of wiper use needed to maintain clear visibility. On bathroom glass, the waterproof coating reduces the amount of water that remains on the surface after use and contributes to reducing limescale and water spot build-up over time, which can prolong the time between cleaning sessions for shower screens and mirrors. The coating is durable and does not wash off immediately after application — a single application provides extended protection, though reapplication over time maintains the effectiveness of the coating as it wears.

The spray is suitable for use on car windscreens, side windows, rear glass, bathroom mirrors, and shower screens — covering the full range of glass surfaces in a car and home that benefit from anti-fog and waterproof treatment. A single 20ml bottle is sufficient to treat multiple surfaces, and the compact size means it can be kept wherever it is most convenient: in the glove box for car glass, in the bathroom cabinet for mirrors and shower screens, or in a travel bag for use when away from home. The spray-and-wipe application method requires no special tools, no primer, and no professional application — spray onto the clean glass surface, wipe to distribute the formula evenly, and allow to cure. The simplicity of the application process means the treatment can be reapplied as needed without difficulty.

At 20ml, the bottle is small enough to keep permanently in a car glove box, bathroom cabinet, or travel toiletry bag without taking up meaningful space. The compact size also means it can be taken on a flight in a standard 100ml liquids bag without using a significant portion of the allowance. For regular use, the 20ml capacity provides enough product for multiple applications across multiple surfaces, and the small footprint means it is practical to keep several bottles — one in the car, one in the bathroom — rather than moving a single bottle between locations. The spray bottle format means application is clean and controlled, with no need to pour onto a cloth or measure out a specific amount.
