It is a commonly held belief that windows should not be cleaned when it rains because the rain will just make them dirty again.
Is this really a fact?
The simple answer is βNoβ.
Although in some parts of Europe and the UK many people believe having their windows cleaned when it rains is a waste of time, it is normal practice for window cleaners to carry on in mostl weather except storms and high winds.
Windows need cleaning because they get dirty not because they get wet.
Back in the days when most houses had chimneys that were belching smoke, it probably would of been true that by the time the rain drops reached the ground they were full of dirt and smoke particles. With the Clean Air Act, that situation has changed.
Nowadays the three major causes of dirty windows are dust, pollen and droppings. If these are present on the window glass when it rains, the residue in the rain attaches itself to the dirt and can often make the windows look worse.
When windows are clean the rain will simply run off and the glass continues to remain clean.
