Streak-free windows – how to prevent annoying streaks when cleaning windows

Crystal-clear results with tips from the professionals

Window cleaning is without doubt one of the most unpopular household chores. It is particularly infuriating when your efforts are ultimately ruined by undesirable streaks. But these can be easily prevented. Here are our tried-and-tested tips from real window cleaning professionals for you to use in your own home!

Working swiftly helps!

When window cleaning, streaks are caused by the dried-on residues of the cleaning solution and dirt, because the fluid was not removed quickly enough or because the rubber of the squeegee did not remove the fluid thoroughly enough. The working speed, the cleanliness of the washing water and a top-quality squeegee are thus the keys to success. The legend that sunlight is supposedly responsible for streaks is only true to the extent that the pane is heated up by the solar radiation and any residues can thus dry onto the pane more quickly. You should also avoid taking the squeegee off the pane – always follow your motions smoothly through to the end. Important: when squeegeeing, your motions should always overlap slightly. If, in spite of all precautions, the squeegee leaves behind a couple of streaks, these can easily be polished away with a microfiber cloth or a chamois.

You can also use newspaper as a ‘DIY’ tool for drying off the pane. However, there is always the risk that the newsprint will leave behind dark edges on the frame or on the windowsill. We thus recommend that you clean your windows with a washer, a squeegee and a microfiber glass cloth. Cloths which are washed with fabric softener also leave behind annoying streaks – you should therefore avoid using fabric softener. If you follow these tips, you will give yourself the best chance of achieving streak-free results.

Wait for a dry day to do your window cleaning and make sure that you have the right tools to hand. Equipped with professional cleaning tools, you can work in a much simpler, faster and more precise manner – there will be no time whatsoever for streaks to form and you will have more time for the finer things in life.
