Window Cleaning: Don’t Make These Mistakes When Cleaning Exterior Windows

Exterior window cleaning is sometimes refreshing and sometimes bothersome. It depends on many things, like the time of year, the size and accessibility of your exterior windows, how dirty they are, and of course, the mood that you’re in. Other factors that affect the outcome of the cleanliness of your exterior windows after washing (as well as whether it was a positive experience or a nuisance) include your method of cleaning and the supplies you’re using.

It’s a relatively simple process but not always straightforward, and making mistakes that are commonly made when washing exterior windows may make your efforts null, result in your windows needing to be washed again soon after, or even cause damage to your windows, none of which we want! Here are some mistakes to avoid when cleaning exterior windows:

Not Removing Dirt & Dust First

Exterior windows, especially those that are at or near the ground level, are prone to the serious build-up of dirt, dust, and debris. It’s not so much important why as it is that you prioritize first completely removing all dirt, dust, and debris before moving on to the usual, lighter cleaning step which leaves windows shining. Experts recommend applying the same cleaning solution generously and scrubbing with a microfiber towel, then rinsing.

Using the Wrong Cleaner

Using the wrong cleaning solution for exterior windows is a common mistake that can leave them looking hazy and streaky. Many DIY guides recommend adding a drop or two of dish soap per gallon of water, and if your windows are REALLY dirty, adding one part vinegar to the solution.

Not Using the Squeegee

Towels and other drying supplies don’t always work to the degree exterior windows need to achieve that sparkly clean shine. Squeegees are cheap and extremely effective in completely removing all remaining liquid after you’ve washed and rinsed your exterior windows.

Not Using Distilled Water

A very common mistake is using “hard” water, or water that isn’t distilled. Non-distilled water often has mineral build ups that leave water spots, streaks, and smears no matter how well and enthusiastically you wash your exterior windows. In other words, it’s worth the effort in buying distilled water or filling your wash bucket from a filtered water source from inside!

Washing on…Sunny Days?

You would think that washing your exterior windows on a sunny day makes sense, and while it does if you’re thinking about utilizing bright, natural light to better see how your cleaning efforts are going, you’re actually making a mistake!

Even when the temperature isn’t too high, direct sunlight on your exterior windows actually causes window cleaning solutions to dry too quickly. This often leads to streaks and smears on your windows when wiping, which can then make your windows hazy or appear to have an opaque film on their surface.
