A cleaning expert has revealed that an everyday cupboard staple—washing-up liquid—is far more effective than commercial glass cleaners for achieving streak-free, sparkling windows. Lily, a cleaning influencer who shares tips on her social media channels, says the secret is simply washing-up liquid (she prefers Fairy), water in a bucket, and a microfibre towel.
Simple Method for Streak-Free Windows
Lily explains that the key to perfect windows is to use the washing-up liquid solution with a microfibre cloth, then dry them off with a glass cloth for the best results. She also advises using a brush to get into the nooks and crannies when the windows are open, ensuring every part is clean as part of a home reset.
Before cleaning, it is important to remove any dust from the windows, otherwise you risk simply rubbing dust around. Focus on spots like fingerprints, bird droppings, or grime. For exterior windows, work in sections so the solution does not dry and leave marks, which can make the windows look worse than before.
Technique Matters
Lily recommends moving the cloth up and down over the window, rather than in circular motions, to replicate the action of a squeegee. This technique yields a much better result. Fairy washing-up liquid is highly effective because its concentrated surfactant formula quickly cuts through grease, fingerprints, and grime. It also provides excellent slip, allowing a window squeegee to glide smoothly without dragging or squeaking, resulting in a flawless, streak-free shine.
Viewers Confirm the Hack Works
In the comments, one user wrote: “I’ve only just started using Fairy washing-up liquid to clean my windows. Previously, I used glass cleaner and was left with streaks. No more streaks for me!” Lily responded that the method is “amazing,” and noted that if you don't have any in your cupboard, you can pick it up for just 89p at Savers.
Another commenter recommended cleaning tricky bits in the windows with a paintbrush, saying that is how they keep them sparkling all year round. Lily agreed, saying she uses them too, but emphasised that trial and error is the best way to see what works for you.
Cost-Effective and Eco-Friendly Alternative
This simple, inexpensive hack offers a cost-effective and eco-friendly alternative to specialized glass cleaners. With a bottle of washing-up liquid costing as little as 89p, households can achieve professional-quality results without spending extra money on products that often leave streaks.
