Window cleaning is a tiresome topic. Disturbing streaks often appear on the glass surface. Six typical errors are usually to blame for the stripes.
1. Incorrect amount of detergent
If the cleaning water contains too little cleaning agent, the dirt is difficult to remove. But if you use too much cleaning agent, too many residues remain on the glass. If you buy special window cleaning agents, you should therefore observe the dosage recommendation given there.
Ordinary washing-up liquid is also sufficient. This is dosed rather carefully with a few drops. If the local water contains too much lime, a little vinegar-based cleaner or ammonia in the cleaning water will prevent limescale stains later on.
2. Insect droppings not loosened enough
This dirt often adheres very strongly and leaves streaks when it is removed. If you want to work carefully, first soak the dirt on the window with a wet sponge. If you use a dish sponge, you have to make sure it is on the right side. The rough side for stubborn pan dirt leaves scratches on the glass.
3. Clean window frames
4. Puller not dry
Experts advise wiping the rubber lip after each stop. In addition, the puller is only used in the wet window area. In general, you have to make sure that the rubber lip is straight and stable when using the tool.
It is also important to use the squeegee correctly: Move it straight and not in a wavy line over the window.
If you don’t have a squeegee, you can use a squeegee to remove the remaining water after cleaning microfiber cloth removed. It is important to polish the pane so that no streaks can be seen.
5. Let the water dry on the window
Windows can also be cleaned when the sun is shining. This is often not recommended, but the sun has an advantage: you can clearly see the areas that need to be polished. However, the windows must not dry before they are removed – the sun should therefore not shine directly on the panes. That gives streaks. It is therefore advisable to work briskly – and not to clean when it is extremely hot.
6. Grandma’s trick with newspaper
Often read, often guessed, nonetheless nonsense: newspaper is supposed to guarantee streak-free glass. But the printer’s ink can leave black marks. A soft cloth or the classic chamois leather are simply better. The trick with the nylon stockings does not convince everyone either – they are said to be easier to polish window panes than with a chamois leather.
