Wynn’s Crystal Clean & Protect 500ml W21090 – Diesel AdBlue & SCR System Cleaning Additive
Wynn’s Crystal Clean & Protect 500ml W21090 is a specialist AdBlue treatment for diesel vehicles equipped with SCR (Selective Catalytic Reduction) systems. It is designed to help keep the AdBlue system clean and reduce the formation and build-up of crystallised deposits.
AdBlue crystallisation can contribute to deposits within the SCR system and affect components involved in AdBlue delivery. Wynn’s Crystal Clean & Protect provides preventative maintenance by helping keep the system cleaner and supporting reliable operation of the vehicle’s emissions-control system.
