Why Rain Is Now A Window Cleaner’s Enemy

Why Rain Doesn’t Ruin Window Cleaning

It’s hard to find someone who genuinely loves rain. Of course, sitting by a fireplace with a good book while listening to raindrops on the window can feel cozy and peaceful.

But in reality, rain often arrives at the worst times—during a planned walk, a barbecue, a morning dog walk, or a long car trip. Many clients feel that washing windows during rainy seasons is pointless and often ask why we recommend spring and fall cleanings, when rain is most likely. The answer might surprise them: we’re not afraid of rain.

Windows vs. Cars

Washing windows is very different from washing a car. When it rains on a car, dirt from the roads mixes with the water and makes the vehicle dirty again. For windows, however, rain itself is usually just clean water. If your windows are already squeaky-clean, raindrops slide off, forming clear puddles on the sill or falling harmlessly to the ground. Dirty windows, on the other hand, attract streaks as rain mixes with grime.

Timing Matters

It may seem counterintuitive, but washing windows just before it rains can be better than waiting until after. Clean glass allows raindrops to flow off without leaving streaks, while dirty glass gets messier. This is why we stick to scheduled cleanings, even when it’s raining.

Seasonal Cleaning Recommendations

For the best results during rainy seasons, we recommend cleaning windows every spring and fall. This ensures that your glass remains clear and streak-free. Essentially, rain helps us do our job—it makes clean windows cleaner and dirty windows dirtier.
