How To Get Rid of Window Streaks

By Subodh / May 25, 2011

A streaky window can often look very unattractive, especially if you are normally a compulsive clean “freak.” It is often one of the most noticeable kinds of dirt spots because of the way the light shines through the window.

Why so Important?

A clean window always indicates professionalism in a commercial building. Within a home, it helps provide a more inviting atmosphere.

What Causes Window Streaks?

Window streaks are hard to remove. Therefore, if you know what causes them it will help prevent them from returning.

Here are main reasons why window streaks occur (prevention tips provided below this list):

  • Use of too much or too little cleaner-If you use too high of a concentrate of cleaner that can be a problem as it leaves buildup and streaks. However, if you use too little of cleaner concentrate it does not clean very well, thus leaving streaks.
  • Cleaning in a hurry-Of course if you are careless you cannot possibly do as good of a job as you hoped. This is in fact the worst way to cause streak marks on the windows.
  • You tried to clean with a dirty cloth. This is a typical problem when using cleaning rags or old clothing. You can avoid this problem by just making sure you sort your cloths and towel into appropriate piles (i.e. do not mix grease or oil cleaning towels in with kitchen or bathroom cleaning towels).
  • Using sloppy cleaning technique-For instance, maybe you have used a towel or rag that is not completely dry. Either that or you have washed a window and did not use squeegee or towels to dry it off afterwards
  • Application of wrong window cleaner-Usually the best glass cleaner has either ammonia or vinegar in it. Any other kinds of solutions may be poorly composed with ingredients that can cause streaks. Remember, you should also find out if the cleaner is meant to be deleted or not.

More detailed window cleaning tips are shown below:

  • Wipe and wash properly. Whether you decide to wipe horizontally or vertically you should apply even pressure the entire time. Make sure you wipe dry as soon as you have wet an area.
  • Learn the proper squeegee technique. A squeegee (as you probably know) is a device with rubber on one side and sponge/scrubber on another. Use even pressure come time to use the rubber part on the window to remove the excess water.
  • Wipe the window dry immediately. If you missed a spot when scraping the water off, follow immediately with a dry fibreless cloth or paper towel. Otherwise, if you have used a spray bottle spray the right amount and then wipe it dry immediately.
  • Do not clean window on sunny or windy days (or frozen days). These are times when the water will evaporate from the glass before you can wipe it off. The exception of course is when it is freezing outside.

In this case, you would not even be able to wipe the water off at all. Of course, this applies more for doing the outside of the windows but also could affect work on the inside.
