How to wash windows – step by step for a sparkling result

Washing windows and getting them really clean without streaks can feel difficult—but with the right method, it becomes easy. Whether you need to clean very dirty windows outdoors or simply freshen up the inside, there are tricks that will help you succeed. Here we explain how to clean your windows step by step—from pre-washing to window cleaning—for a spotless and clear result every time.

Remove heavy dirt before cleaning

If there is a lot of dirt on the glass, for example if you live near a road, the outside of the glass can become covered with particles—these cannot be removed by simply cleaning the windows. They need to be removed before you start cleaning. Regardless of which cleaning product you use, it will become “messy” if you do not remove road dust first. 

Think of it like washing a car: if the car is muddy, you cannot start by polishing it—you need to wash off the mud first. The same applies to windows. The inside, on the other hand, is rarely so dirty that it cannot simply be cleaned.

For a very dirty exterior, do the following:

1. Prepare the cleaning solution

-  Warm water in a bucket
- A splash of dish soap—start with just 1 drop; that is often enough. 

2. Prepare the tools

- Window squeegee: A good squeegee is key.
- Microfiber cloth or sponge: For applying the cleaning solution.
- Towels or cloths: For drying the window edges and catching excess water.

3. Clean the window

- Start by wiping the window frame and removing dirt or dust. This prevents dirt from spreading when you start cleaning.
- Use your microfiber cloth or sponge to apply the cleaning solution to the window. Make sure to cover the entire surface.

4. Squeegee the window

- Use the window squeegee to remove the solution. Start at the top of the window and pull the squeegee straight downward.
- Wipe the squeegee blade with a dry cloth after each stroke to prevent streaks.

5. Dry the edges

- Use a dry cloth to wipe the window frames and edges where excess liquid may have collected. This helps prevent water marks.

6. Check the result

- If you see any streaks or spots, use a dry microfiber cloth and Västerbottenssåpa window cleaning spray. Spray it on and polish with a dry cloth or a lint-free paper towel.

Tips for streak-free window cleaning

- Clean the windows when it is cloudy: If you clean them in direct sunlight, the windows may dry too quickly, which can cause streaks.

- Work systematically: Start at the top and work your way down to prevent drops from the upper sections from ruining the lower sections that have already been cleaned.

- Remove any streaks with window cleaning spray and a cloth/paper towel instead of starting over with the squeegee.

By following these steps, you can get windows that are clear and free from streaks!

How do you clean between the window panes?

Many windows can be separated, and unfortunately dirt can find its way in there as well. But it is rarely worse than being able to use just window cleaner and a cloth. Spray it on and wipe in sweeping movements from top to bottom.

Västerbottenssåpa window cleaning spray contains a dissolving and a polishing component. After about four strokes over the surface, following application, the surface is clean.

How do you clean the inside of the window?

The same applies to the inside as between the panes. Spray it on and wipe it off for completely clean windows.
