Cleaning inside of rear window
 

Is there a special way to clean the inside of the rear window because it has the heating elements? Can I spray on Stoners Invisible Glass and wipe the window clean with a microfiber? Will that do any damage do the heating elements?

exactly what you do. you'll be fine.

I try to use as little cleaner as possible and try to clean left to right the way the grid is (somewhat) running.

I have found too much cleaner will cause it to fog easier.
