Cleaning of hard to get windows.

Hello Folks, this my first post. What is the easiest way to clean cab & cap windows with cap in place?

 

No easy way from my experience
I pull the cap back once or twice a year and scub
Unless someone has a miracle cure it’s the price I pay to have a cap
Mineral deposits and water stains require work

 

This is what I use for hard to reach windows:

PROXRACER Windshield Cleaner 3 Washable Reusable Microfiber Bonnets Window Cleaner with Extendable Aluminum Handle for Car & Home Glass Use Windshield Cleaning Tool (Black)

Cleaning is the exact reason I spent the extra $10 and got the removable rear window for the cap. Have I done it? Yes, once in 12 years.
