Compatible with all standard AdBlue and DEF fluids, it optimizes exhaust aftertreatment performance, reduces emissions, extends component life, and supports fuel efficiency—ideal for diesel vehicles and commercial fleets seeking reliable, long-term SCR system maintenance. ## Description A clean and efficient SCR system is crucial for diesel vehicles with AdBlue© technology. This 500ml concentrate has been specially developed for use with AdBlue© and helps prevent the formation of harmful crystals that can accumulate over time and affect the performance of the system. Without regular maintenance, deposits form in the tank, injector or pump, which can lead to blockages, loss of efficiency and high repair costs. This advanced additive ensures that SCR components remain clean and functional. By avoiding deposits, free flow of AdBlue© and precise dosage is ensured for effective NOx reduction and permanently reliable SCR performance. The result: better energy efficiency, lower emissions and long-term compliance with environmental regulations. Particularly beneficial for diesel cars and commercial fleets as system failures are minimized due to SCR interference. It reduces operating costs and extends the life of important components. The additive is fully compatible with all approved AdBlue© and DEF formulations and can be added directly to the tank without additional tools - a practical and easy maintenance solution. Review: Soy profesional en el transporte. Tengo un trailer y realmente es un producto muy eficaz, dándome el camión ya fallo. Mala calidad de adblue. Fue capaz de limpiar y solucionar el problema. Excelente Solo quedaría una cosa con este producto tan bueno y es que el consumo que hace un trailer. Por ejemplo el mio es alrrededor 4700 litros mensuales. Para nosotros los profesionales necesitaríamos un envase almenas de 5 litros. Y en lo posible poner un precio para los profesionales Review: Worked as claimed so definitely worth the cash and the 5* rating given. ## Features - ✅ HELPS PREVENT CRYSTAL FORMATION IN ADBLUE SYSTEMS: Specially developed for use with AdBlue, this highly effective 500ml additive helps prevent harmful crystal formation in the SCR circuit (selective catalytic reduction). Such crystals can clog injectors, pumps and AdBlue tanks and lead to loss of performance or mechanical damage. By keeping the system clean, this additive protects important components and ensures a smooth and efficient operation of the SCR system in the long term. - ✅ EXTENDS THE LIFE OF SCR COMPONENTS: Without maintenance, it can lead to slight crystal formation in the SCR system over time – especially for vehicles with high mileage or long idle phases. The advanced formula of this additive actively works against such deposits in the AdBlue tank, injector and pump. Regular use ensures more precise dosing and permanently reduced emissions - for cleaner and more effective exhaust aftertreatment. - Optimises the operation of the SCR system and improves fuel consumption: a clean and unhindered SCR system allows the diesel engine to function more efficiently and meets the strictest environmental requirements. This additive optimises the flow and injection of the AdBlue system, reduces emissions and supports more economical fuel use. - Reduces breakdowns and unexpected failures: crystal formation in the SCR system is a common cause of failures and costly repairs on modern diesel vehicles. The preventive use of this additive can significantly reduce the risk of blockages and malfunctions - especially beneficial for fleets, frequent drivers and anyone who needs a reliable vehicle. - ✅ BULK PACK FOR LONGER USE - TREATS UP TO 60 LITRE ADBLUE: This 500ml bottle has been designed for convenient and economical maintenance - ideal for vehicles with high AdBlue consumption. Compatible with all standard diesel exhaust fluids (DEF) and AdBlue formulations, the additive is easy to apply - simply add directly to the AdBlue tank when filling. For optimal protection, it is recommended to use at every refueling process. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BNLD1CG9 | | Brand | Wynn's | | Customer Reviews | 4.6 4.6 out of 5 stars (367) | | Date First Available | 9 December 2024 | | Item Weight | 560 g | | Item model number | W21090 | | Manufacturer | Wynn's | | Manufacturer Part Number | W21090 | | Model | W21090 | | Product Dimensions | 4.6 x 9 x 25.6 cm; 560 g | ## Images ![Wynn's Crystal Clean & Protect - Additive for Use with AdBlue© - Prevents Crystal Formation in SCR Systems - Improves Performance of Exhaust Aftertreatment on Diesel Engines - 500ml - Image 1](https://m.media-amazon.com/images/I/51oN51ju5XL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by R***A on 5 August 2025* Soy profesional en el transporte.
