Hola amigos, Mause here. Let me tell you something I’ve learned over the last 30 years in the cleaning business. When you’ve been at it as long as I have, you pick up on things people don't always think about. One of those is why washing windows on a hot day is just not a good idea. You might think, "The sun’s out, it’s a perfect day to get some work done." But let me share 3 reasons why that’s not the case.

Reason #1: Streaks galore

When it’s hot outside, the sun dries the windows too fast, leaving those ugly streaks behind. You see, the water and the window cleaning product evaporate too quickly, which is what causes those spots and lines. You don’t want to leave a window looking worse than when you started, do you? That’s why a cooler day, with a nice breeze, is much better for the job.

Reason #2: Risk of breaking windows

Now, this might sound like an old wives' tale, but I’ve seen it happen with my own eyes. When the temperature gets really high, you’re playing with fire. Maybe one in a hundred times, but that’s enough to make me think twice. The glass can be so hot that when you splash cold water on it, boom—it cracks. And let me tell you, replacing a window is not cheap or fun.

Reason #3: Your safety

Here’s something close to my heart—safety. You’ve got to protect yourself, especially in the heat. I’ve seen guys get dizzy up on those ladders when the sun’s beating down on them, the heat bouncing off the glass right back into their faces. I always tell my crew to wear their sunglasses, but even with those, the heat can be too much. One slip on that ladder, and it’s game over. Safety first, always.

In this business, it’s about doing the job right and looking out for other people. We don’t just clean windows; we solve problems, and we take care of each other. So next time you’re thinking about getting up there with a squeegee on a scorching day, remember these tips from a man who’s been around long enough to know. Wait for cooler weather. Take care out there, amigos.
