## Overview

Wynn's Crystal Clean & Protect is a 125ml additive designed to prevent crystallisation in diesel SCR systems using AdBlue. By dissolving early crystal deposits in injectors, pumps, and tanks, it maintains optimal emission control performance, reduces costly repairs, and enhances fuel efficiency. Compatible with all AdBlue and DEF fluids, it treats up to 15 litres per dose and is essential for reliable, eco-friendly diesel operation.

## Description

Maintaining a clean and efficient Selective Catalytic Reduction (SCR) system is essential for diesel vehicles that utilise AdBlue as part of their emission control strategy. This advanced additive, developed specifically for use with AdBlue, helps prevent the formation of harmful crystals that can compromise the performance of the SCR system. Crystal deposits may accumulate over time in the AdBlue tank, injector, or pump unit, leading to restricted fluid flow, reduced system efficiency, and costly mechanical issues. This treatment works to dissolve early-stage crystallisation, ensuring critical SCR components remain clean and unobstructed. By keeping the system free from deposits, it supports smoother operation, improved dosing accuracy, and optimal conversion of NOx emissions—helping diesel engines meet stringent environmental standards. The regular use of this additive for AdBlue helps extend the lifespan of the SCR system, reducing the risk of unexpected breakdowns and vehicle downtime. Whether in private diesel cars or commercial fleets, it contributes to better fuel efficiency, reliable performance, and consistent emissions compliance. Formulated to be fully compatible with all recognised AdBlue and Diesel Exhaust Fluid (DEF) types, the additive is simple to apply—just pour it directly into the AdBlue tank during refills. Each 125ml bottle treats up to 15 litres of AdBlue, making it a convenient and cost-effective solution for preventive maintenance. For best results, it is recommended to use the product at every AdBlue refill to provide ongoing protection against crystallisation and keep the SCR system operating at peak performance.

Review: Work for purpose - Good stuff, second time buying and worked perfect in my Diesel car.
Review: Very good! - Problem had an easy fix after half a day from putting the liquid in and has very good value for money. Would highly recommend.

## Features

- Causes serious eye damage.
- Contains 1,2-benzisothiazol-3(2H)-one. May produce an allergic reaction.
- ✅ 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.
- ✅ 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.
- ✅ 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.
- ✅ 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.
- ✅ 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.
