Sunroof service

Now that the rains have come, I have noticed that my sunroof isn’t as fast at retracting as it used to be. I’m assuming rust or just plain dirty.

I would like to know if anyone has tips or a nice method to cleaning/servicing our sunroofs? Thanks

You might try cleaning out the rails that it slides on. Sometimes the grease gets dirty and gums up. Mabie clean it up best you can and relube it.
