Wynns Crystal Clean & Protect 125ml

Part Number: WYNW21002

Wynns Crystal Clean & Protect is a specialized treatment designed specifically for AdBlue® (Diesel Exhaust Fluid/DEF) systems in modern diesel vehicles. This innovative 125ml formula contains advanced cleaning agents and protective compounds that remove deposits, prevent crystallization, and protect critical AdBlue® components including injectors, pumps, and sensors. Regular use helps maintain optimal SCR (Selective Catalytic Reduction) system operation, prevent costly failures, and ensure continued compliance with emissions regulations.

Product Characteristics

• Dissolves urea crystals that can clog AdBlue® injectors.
• Prevents injector clogging and extends service life.
• Keeps sensors clean for accurate readings.
• Lubricates and protects AdBlue® delivery pumps.
• Ensures correct dosing for efficient NOx reduction.
• Protects against urea-related corrosion.
• Improves resistance of AdBlue® to freezing.
• Helps avoid SCR warning lights and limp mode.
• Maintains compliance with emissions standards.
• Prevents expensive AdBlue® system repairs.

Storage & Shelf Life: Store sealed in a cool, dry place away from direct sunlight and frost. Shelf life 3 years from production date.

How to Use

• Add entire 125ml bottle directly to the AdBlue® tank during refilling.
• One bottle treats 10–15 litres of AdBlue® fluid.
• For preventative care, use with every third AdBlue® refill or every 10,000 miles.
• For vehicles with warning lights or performance issues, add to a nearly empty AdBlue® tank before refilling.
• Safe for all passenger cars, SUVs, vans, and commercial diesel vehicles using AdBlue®/DEF.

 

Crystal Clean & Protect is particularly valuable for vehicles operating in challenging conditions such as frequent short trips, extreme temperatures, or extended idling where AdBlue® issues are common. Prevents injector and sensor failures that can lead to limp mode or immobilization.

Designed to work with standard AdBlue®/DEF fluid without altering chemical properties. Regular use helps prevent crystallization, especially in vehicles not regularly driven at highway speeds. Note: Always add only to the AdBlue®/DEF tank (blue cap), not the diesel fuel tank.
