Wynn's Crystal Clean & Protect - Additive for Use with AdBlue - Prevents Crystallisation in SCR Systems - Enhances Diesel Emission Control Performance - 125ml
Why we love it
Prevents costly repairs and downtime.
Compatible with all AdBlue fluids.
Easy to use at every fill.
Main highlights- SAFE FOR ALL VEHICLES USING ADBLUE – EASY APPLICATION: This product is compatible with all Diesel Exhaust Fluid (DEF) and AdBlue systems. It can be added directly to the AdBlue tank without any special tools or procedures. One 125ml bottle treats up to 15 litres of AdBlue, providing cost-effective and preventive maintenance every time you refill.
- HELPS PREVENT CRYSTAL FORMATION IN SYSTEMS USING ADBLUE: Specially formulated for use with AdBlue, this additive helps prevent the formation of harmful crystals in the SCR (Selective Catalytic Reduction) system. By keeping components such as the injector, pump, and AdBlue tank clean, it supports the continuous and efficient operation of the emissions control system and helps reduce the risk of costly repairs due to crystallisation.
- HELPS AVOID DOWNTIME AND SYSTEM FAILURES: Crystallisation in systems using AdBlue can lead to unexpected vehicle breakdowns and maintenance issues. This additive helps to prevent those issues, keeping your diesel engine running smoothly and reducing the risk of sudden system failure. It's particularly valuable for commercial fleets and long-distance drivers who depend on consistent reliability.
- ENHANCES THE PERFORMANCE OF SYSTEMS THAT USE ADBLUE: When used regularly, this product optimises the performance of the SCR system by maintaining clean operating conditions for all key components. Cleaner injectors and pumps support more accurate AdBlue dosing, reducing emissions and contributing to better fuel economy and environmental compliance.
- CLEANING EFFECT FOR SCR COMPONENTS: Designed to work in conjunction with AdBlue, this treatment provides an effective cleaning action for SCR system components, including the tank and injector. It dissolves early crystal formations before they build into hard deposits, ensuring that the system remains clean and efficient. This contributes to better fluid atomisation and optimal performance of the diesel exhaust treatment process.
