[RE-wrenches] Cleaning Modules

[Corey Shalanski]

Greetings Wrenches,

I posed this question to the group a number of years ago and would like to
ask it again, in case any new members have new ideas or any elders have
adjusted their approach.

I am wondering if anyone can offer tried-and-true tips for cleaning
modules: tools, materials, methods? I am particularly interested in
cleaning solutions for large commercial flat-roof installations.

I have always had success using a mild soap solution to help loosen
dirt/pollen, but I recently read an article specifically advising against
this:

Any reactions?
