✅ REMOVES STUBBORN INSECTS & DIRT: The Rain-X screenwash with insect remover & rain repellent is specially formulated to tackle the toughest grime, including stubborn insect residue, dirt, and mud. This powerful cleaning solution effortlessly breaks down and lifts away even the most persistent contaminants that can accumulate on windscreens during Spring and Summer drives. Unlike standard screenwash, this formula is engineered to cut through organic and inorganic debris without leaving streaks or smudges. The advanced cleansing agents dissolve dirt particles on contact, making it easier for wipers to clear the windscreen effectively.
✅ ADVANCED HYDROPHOBIC TECHNOLOGY: Infused with cutting-edge hydrophobic technology, this screenwash doesn’t just clean—it also provides an invisible rain-repellent barrier that actively improves driving visibility. The innovative formula generates microscopic water droplets that bead up and roll off the windscreen effortlessly, preventing rain from obstructing the driver’s view. This effect is particularly beneficial in sudden Summer downpours, reducing the need for constant wiper use and maintaining a clear field of vision. The hydrophobic layer also helps in repelling dirt and dust, keeping the windscreen cleaner for longer.
✅ READY-TO-USE FORMULA: Designed for convenience, the screenwash comes in a perfectly blended, ready-to-use formulation. Unlike concentrated screen washes that require dilution, this product is pre-mixed to provide the ideal balance of cleaning agents and foam control. This ensures optimal performance without the guesswork of achieving the right mixture. Simply pour it directly into the windscreen washer reservoir and enjoy instant results with no additional preparation required. The optimised foam control prevents excessive suds, ensuring smooth and efficient operation of the windshield washer system.
✅ ENHANCED FORMULA WITH BACTERIA PREVENTION: The specialised formula of this product goes beyond cleaning and visibility enhancement—it also actively prevents the formation of bacteria within the windscreen washer system. Over time, moisture and organic debris can create an environment where bacteria and mould thrive, leading to unpleasant odours and potential blockages. This advanced formula contains antimicrobial properties that inhibit bacterial growth, keeping the washer fluid circuit clean and hygienic. By maintaining a bacteria-free system, the product extends the lifespan of windshield washer components, ensuring long-term performance without the risk of contamination.
✅ REFRESHING SCENT WITH EVERY USE: Unlike conventional screenwash that may leave behind strong chemical odours, this formula has been crafted with a pleasant and refreshing scent. Every application releases a subtle yet invigorating fragrance that enhances the overall driving experience. The balanced formulation ensures that the scent is not overpowering, making it suitable for all users who appreciate a fresh and clean-smelling vehicle environment.

✅ REMOVES ALL TYPES OF DIRT AND LEAVES A WATER-REPELLENT FILM: The powerful cleaning agents in the solution effectively break down stubborn dirt, making it easy to wipe away without excessive scrubbing or multiple wiper passes. In addition to its exceptional cleaning performance, this screenwash contains water-repelling properties that leave behind a durable hydrophobic film on the glass.

✅ PROTECTS DOWN TO -15°C AND CAN BE DILUTED FOR YEAR-ROUND USE: Designed for all-season performance, the concentrated screenwash offers superior protection against freezing temperatures, making it ideal for harsh winter conditions. The formula remains effective even in extreme cold, preventing the windscreen washer system from freezing and ensuring that fluid can be sprayed consistently.

In warmer months, the concentrated solution can be diluted to suit Spring and Summer weather, ensuring that it remains efficient while being cost-effective.
✅ EASY TO USE FOR OPTIMAL PERFORMANCE: To achieve the best results, it is recommended to empty the windscreen washer reservoir before adding the screenwash. This ensures that the solution works at maximum efficiency without being diluted or altered by previously used washer fluids. The product is designed to be poured directly into the reservoir without requiring additional mixing, making it convenient and hassle-free. By following this simple process, the screen wash delivers optimal performance, maintaining a clear and clean windscreen with every use.
✅ METHANOL-FREE FORMULA FOR A SAFE AND ENVIRONMENTALLY FRIENDLY CHOICE: The concentrated screenwash is formulated without methanol, making it a safer and more environmentally friendly option compared to traditional washer fluids.

Rain-X Rain Repellent & Anti-Fog Treatment Value Pack - Hydrophobic Formula for Clear Visibility and Fog-Free Windscreen - Ideal for Car Windows & Interior Mirrors - 200ml x 2

10% OffFree Shipping

Why We Love It

Repels rain and snow.
Enhances driving visibility.
Prevents window fogging.

Main Highlights

✅ RAIN-X RAIN REPELLENT TREATMENT: This high-performance formula repels rain, snow, sleet, and other forms of precipitation, ensuring clear visibility during adverse weather conditions. As water droplets land on the treated surface, the hydrophobic coating causes the droplets to form into larger beads, which quickly roll off the glass, improving visibility and reducing the need for windscreen wipers. This treatment works efficiently to enhance driving safety in wet conditions, making it easier for drivers to maintain control of the vehicle and reduce distractions caused by poor visibility.
✅ HYDROPHOBIC TECHNOLOGY FOR SUPERIOR PERFORMANCE: Rain-X employs exclusive hydrophobic technology, providing unmatched protection against the elements. The hydrophobic formula in the Rain-X Rain Repellent treatment concentrates the water droplets that hit the windscreen and directs them towards the sides of the vehicle. This unique technology works by reducing the surface tension on the glass, which makes it harder for water to stay in place, promoting a rapid drainage effect as you drive.
✅ RAIN-X ANTI-FOG FOR INTERIOR WINDOWS: The Rain-X anti-fog is specially formulated to prevent fogging on the interior of car windows, including the windscreen and rear-view mirror. It is designed to combat the condensation that often occurs in the car when there is a sudden change in temperature or humidity levels. Whether it's the result of cold mornings, high humidity, or drastic weather changes, the anti-fog keeps interior windows clear, improving visibility and driving safety. The innovative formula works by creating a barrier that prevents the buildup of moisture, stopping fog from obstructing the view through the windscreen or mirrors.
✅ IMPROVED FORMULA FOR SUPERIOR ANTI-FOG PERFORMANCE: This powerful solution is perfect for areas with frequent temperature fluctuations or high levels of moisture in the air. Its advanced formula ensures that both the interior windscreen and rear-view mirrors remain fog-free, helping to avoid the potential dangers of impaired visibility during driving.
✅ EASY APPLICATION & LONG-LASTING RESULTS: The application of Rain-X rain repellent and Rain-X anti-fog is straightforward, ensuring hassle-free use. Simply apply a small amount of the rain repellent to the exterior of the car’s windscreen and side windows using a clean, dry cloth. The product will leave an invisible, water-repelling layer that will last through multiple rain showers, providing sustained visibility. For the anti-fog solution, apply a small amount to the inside of the windscreen with a cloth, rub gently, and allow it to dry.
