Greetings everyone. You will need a toothbrush + a small paint brush + AC Delco spray or 40W! First step, blow out the sunroof while it's open, then clean with the brush according to the size of the area, then blow again! After that, use AC Delco spray on the tracks and parts, clean with the brush, dry, and repeat as needed! Then, after drying, spray the moving parts and open and close the sunroof and spray again, then wipe the tracks of excess liquid. Best regards to all.. 💐
