My solar panels were filthy with water spots and ash from a bonfire I had last week and had just started sprinkling rain.

So I grabbed a mobile home brush on an extension paint pole and a squirt bottle with water and a little Blue Coral car wash-wax maby 8-to-1.

Panels were wet so gave each panel 2-3 squirts of soap mixture and proceeded to scrub in perpendicular directions 4-6 panels at a time then rinse and repeat until all 34 panels were cleaned 👌

The rain further rinsed panels into the evening the next day I was amazed in how immaculate they looked I figured the rain would help litigated water spotting but by far exceeded my expectations. 😍

The last time I cleaned them I used the same squirt bottle same brush and dawn dish soap with water cleaning 2 panels at a time and rinsing and they spotted like crazy. ☹

I believe the key component here is the rain. Thoughts?
