Cleaning windows like a pro: here's how to get them really bright
Shiny windows make a world of difference to the look of your home or office. Yet for many, window cleaning is a tedious chore. However, with the right approach and a few simple tools, it becomes a lot easier - and the result is crystal clear glass without streaks or smudges.
When is it time to clean your windows?
There is no set rule, but on average, once a month is a good starting point. In urban areas or on the coast, where windows get dirty faster from exhaust fumes or salt, it is wise to clean more often. Also pay attention to seasonal influences: in spring and autumn there is often more dust and pollen.What do you need for good cleaning?
Good preparation makes all the difference. You don't have to buy expensive products. Just a few basic supplies will go a long way toward an effective clean. Here's what you need:- A soft brush for loose dirt
- A bucket of lukewarm (not hot) water
- A dash of dishwashing liquid (e.g., Dreft) Don't have any Dreft? Any other dishwashing detergent works fine too, as long as you use a small amount.
- A little vinegar or mild all-purpose cleaner
- Sponge
- Window squeegee
- Microfiber cloth The combination of dishwashing detergent and vinegar is particularly effective: it breaks down grease residue and leaves glass clear and streak-free.
Step-by-step plan: washing windows as they should be
- Preparation: remove dust and sand Start by removing loose dirt, sand and cobwebs. To do this, use a soft brush or dry cloth. This will prevent scratching during cleaning.
- Make a mild cleaning mixture Fill a bucket with lukewarm water, add a small splash of Dreft and a little vinegar. Stir the mixture gently. You don't need a foaming bucket. The goal is to loosen dirt and grease without leaving residue.
- Cleaning with sponge or cloth Use a sponge and make gentle, circular motions. Always start at the top and work your way down. This will prevent dirty water from flowing over an already clean area.
- Use a window squeegee Use a window squeegee and draw straight lines downward. Dry the squeegee with a cloth after each movement.
- After-drying with a microfiber cloth Use a dry microfiber cloth to thoroughly dry the edges of the glass and window profile. This will prevent water spots or streaks..
Common mistakes you can easily avoid
- Washing in full sun. When the sun shines brightly on the window, the water dries too quickly. As a result, you get streaks. Therefore, choose an overcast day, or start with the windows on the shady side of your home.
- Using too much product Less is more. A small amount of detergent is enough. An overly concentrated solution can actually leave a greasy film on the glass. So always use in moderation.
- Forgotten edges Properly drying window edges is essential. Drops left behind often cause stains afterwards.
