Rain
or
Shine?
MYTH -
It is sometimes claimed by clients & some window
cleaners that window cleaning cannot be carried out
in the rain.
The Institute of Exterior Cleaning has the FACTS:
"If the windows are properly cleaned, then the rain will simply sheet off the clean glass and the windows continue to remain clean."
WHY? - "The three major things that cause windows to become dirty are:
* Pollen
* Insect droppings
* Dust
If these are present on the glass when it rains, the residue in the rain attaches itself to the dirt and often makes the windows look worse."
