Every autumn the same thing happens: the forecast turns, and people start cancelling window cleans because “there’s no point before the rain.” So let us say it plainly, as people who clean Dublin glass every working day: rain making your windows dirty is a myth.
Why Rain Gets the Blame
Dublin rain is soft. It is not carrying grit down onto your glass, and for most windows it barely reaches the pane in the first place — reveals, sills and the angle of the wall shelter the glass from all but driving rain. When people see spotting after a shower, what they are usually looking at is dirt that was already on the glass, moved around.
What Actually Dirties Dublin Glass
Airborne pollen and dust are the real culprits, with traffic film added on busier roads and salt spray near the seafront. That buildup happens in dry weather just as much as wet — which is why the grey haze along the top of each pane appears in June as reliably as January.
The Purified Water Difference
Here is the part most people have never been told. We clean with purified, deionised water — no soap, no residue. When rain lands on glass cleaned that way, there is nothing on the surface for it to smear. It generally dries clear. The streaky post-rain look mostly belongs to windows cleaned with detergent that was never fully rinsed off.
So Do We Work in the Rain?
Yes. Rain does not affect the result, so we clean straight through it. Wind rarely stops us either, because water-fed poles are light and stable. The honest limits: we do not work during orange weather warnings, and we do work through yellow wind warnings. In a year of cleaning across North and South Dublin, weather has cost us remarkably few days.
