Why should I get my windows cleaned?

Windows should always be cleaned to maintain the integrity of the window. Having a great clear view through your windows is a great benefit and makes your home look and feel clean. In addition, it is important to also clean and lubricate the seals. If not, the seals will dry up and begin to crack which can lead to water leaks. On double pane windows, between the panes is nitrogen gas. If the seals leak, the gas will escape, and moisture will find a way in between the windows leaving what looks like streaks or runs down the window. Many times, it will also become hazy to see out of. Lastly, minerals from rain, pollution, sprinkler water that carries calcium, and other elements can build up on the window. If this is not removed, the sun will bake in the impurities, and it can be very difficult to remove. It is recommended that you clean your windows at least on an annual basis to prevent damage.

Wind and the sun are window cleaners' nemesis. These climatic elements can make working more difficult and uncomfortable. Every building has its own challenges and rewards for the cleaner.

Using a sharp squeegee blade is the first thing. Make sure that there is plenty of water on the window, so the window does not dry is the next most important step. Try not to clean the windows when it is windy and not in the sun. The window will heat up and dry the window up fast, making it hard to not have streaks. Having too much soap in the water will also make the window dry faster. Many cleaners have used vinegar in the water. Vinegar is a mild acid and evaporates most of the residue.

Windows can get build upon them over time and the sun "bakes" the impurities into the pores of the glass. Depending on how long it has been since the window was last cleaned, different scrubbing applications are suggested. Using soapy water and a synthetic bristled brush can scrub deeper and can agitate the window better. A "T" handle and mop cover is the most common scrubber used. There are a variety of different covers available that have different scrubbing power and holds water depending on if you are working on the inside where scrubbing is not needed as much, and less water will drop from the mop. On the outside of the window, there is more dirt so a mop cover that holds more water can be advantageous to the cleaner.

There are different cleaning products for different applications. Typically, dish soap is a good cleaning agent when using window cleaning tools. The soap helps remove grease and grime from the windows and frames at the same time removing the friction away from between the glass and rubber squeegee tools. Water fed poles are a newer system that requires a filtration system to remove impurities from the water.
