I use a "dust off" or similar can of air to blow-off the loose dirt/dust, or some other form of air. Gently wipe the surface with a warm soap & water solution on a microfiber cloth. After cleaning and drying use Plexus spray and gently polish the surface. I use Plexus on everything that is polycarbonate or similar plastic.I am in need of cleaning the gauge cluster center information screen and am wondering what is the best procedure to avoid scratching or damaging the display. This is for a 2017 Limited.
