How to clean windows properly

How to clean windows properly

To maintain a clear view, it’s necessary to clean the windows from time to time. But how often is this actually advisable, and what cleaning products should be used? We’ve addressed the most important questions surrounding window cleaning.

In just a few minutes, you’ll know how to clean your windows without streaks. Of course, you always have the option of  hiring a cleaning lady to clean your windows  , so you don’t have to use a squeegee and wiper yourself.

Window cleaning: How often is it necessary?

There are numerous different approaches to cleaning windows, ranging from infrequent to very regular cleaning. Recommendations for window cleaning typically suggest intervals of 2 to 3 months.

However, if a window is particularly dirty after a downpour, there’s nothing wrong with shortening the cleaning interval. The same applies if your windows are well protected and therefore only need cleaning rarely.

Whether you ultimately clean your windows once a month or only twice a year is best determined by your personal preference. Generally speaking, however, most people feel most comfortable in a very clean house.

Cleaning windows without streaks: Timing is crucial

To make window cleaning particularly easy for you, not only the right accessories are important, but also the timing of the cleaning operation.

Ideally, you should clean your windows when it’s cloudy or when the sun isn’t shining directly on the panes. It’s also more difficult to clean windows streak-free on very hot days. The high evaporation rate causes spots and streaks to form quickly.

This is especially noticeable with large windows, which require a little more time.

Preparing for cleaning

Before you begin cleaning the windows, have an old towel and a cleaning cloth ready to absorb any residual moisture.

To protect the floor or sofa, place the towel below the window. You can wipe along the frame with a cloth to immediately remove any cleaning residue.

Before you begin cleaning the window panes, wipe down the window frame and sill. This ensures that the surrounding surfaces do not re-soil the freshly cleaned panes.

Cleaning supplies and cloths: These accessories are useful

Numerous different cleaning products  are available for cleaning windows. Besides a classic glass cleaner, you can also use window cleaner or window cleaner concentrate, which you need to mix with water beforehand.

In addition to the cleaner, you will need the following items:

  • a cleaning cloth or a sponge for lathering the window panes
  • a bucket of water to wash the sponge
  • a squeegee with a rubber lip to remove the cleaning agent
  • a chamois leather so you can polish the window pane at the end.

Alternatively, you can use electric window cleaners that work using vibrations. Steam window cleaners, on the other hand, rely on heat. These models should therefore not be used on windows with wooden frames.

Tips and tricks for window cleaning

Once the preparations are complete, you can finally begin. Proceed with window cleaning as follows:

  • Apply the cleaner to the entire windshield. A sponge works best for this.
  • Once the surrounding area is covered, use the squeegee to pull off the residue downwards in one smooth motion.
  • Always work in an overlapping fashion so that no gaps remain on the window pane.
  • Finally, wipe the edge of the window pane with a cloth.
  • If necessary, polish the disc afterwards with a chamois leather or a  microfibre cloth.

The best home remedies for cleaning windows

Would you prefer to use home remedies instead of modern cleaning products? There are good options for that too.

Here’s an overview of the most important home remedies for window cleaning:

  • Dish soap: Use only a squirt of dish soap in a bucket of lukewarm water.
  • Vinegar: Unlike dish soap, vinegar primarily dissolves limescale. This versatile cleaner is completely organic and helps prevent streaks. Use approximately 50 ml of vinegar per 5 liters of water.
  • Denatured alcohol: Denatured alcohol can be used similarly to vinegar. However, both have the disadvantage of being quite aggressive, which can damage seals over time.

Caution: A classic method is to wipe windows with newspaper. Unfortunately, this always coats the windows with a layer of fine printer dust, making it easier for dirt to adhere. We therefore advise against this antiquated method.

Having the windows cleaned professionally: Is that the better choice?

Of course, you don’t have to clean your windows yourself; you can also  hire a cleaning service  . This saves you a lot of work and time that you can use for other things.

However, there are also safety aspects to consider. For example, you should never clean windows on upper floors using a ladder, as there is a risk of falling. Always leave complicated cleaning tasks to professional companies that specialize in these areas.

Even if the costs are somewhat higher, the savings in no way justify the risk of a potentially life-threatening fall.

The general rule is that if in doubt, it’s best not to attempt cleaning yourself. Streak-free windows aren’t worth risking your health.
