After a scorching, dry summer, many households may find their windows are looking worse for wear. Throughout the season, windows left open have allowed dust, grime, and pollen to settle into every nook and cranny. Fortunately, a simple cleaning hack using items already found in most kitchens can help restore them to a sparkling condition.

Heath Showman from Lifestyle Blinds, a window treatment expert, explains that a butter knife and a clean cloth are all that's needed to remove stubborn dirt and loose debris from window tracks. He notes that the recent hot, dry weather has contributed to the problem, saying, "This summer has been incredibly hot and incredibly dry meaning the slightest breeze is picking up pollen and dust." He adds that while most people notice dusty windows, they often overlook the debris that accumulates in the crevices they rarely see.

The method is straightforward: dampen a cloth under the tap, wring it out so it's just moist, then wrap it snugly around the tip of a butter knife. Glide the cloth-covered knife along the window tracks to dislodge the grime that has built up over the summer. Showman advises ensuring the cloth is thick enough to prevent the metal edge of the knife from scratching the window frame or glass.

Why focus on window tracks? Showman explains that dust tends to collect in the sliding channels, frame joints, and tiny drainage slots. These areas are often neglected during regular cleaning routines. "Unless you're doing a deep clean, it's unlikely these will be part of a weekly tidy up," he says. The consequences of neglecting them can be more than just unsightly: dirt, dead bugs, and mould can accumulate, potentially hindering the smooth operation of the windows and causing unpleasant odours if mould develops.

To prevent these issues, Showman recommends checking window tracks and crevices every three to four months, and more frequently during particularly dry and dusty periods. After a summer like this one, a little extra attention now can help keep windows functioning well and looking clean throughout the year.
