The window-track trick that saves your bond every time
Window tracks are the inspector's favourite gotcha in Australia because they are the one place you forget and they hold months of dust, dead insects, and gritty paint flecks.
A standard wipe with a cloth pushes the debris into the corners and looks worse than not cleaning at all. The professional method takes five minutes per window. Step one: vacuum the dry track with the brush attachment to lift loose grit — wet first and you create a cement-like sludge. Step two: sprinkle baking soda along the track, spray white vinegar over it, and let the foam sit for two minutes. The reaction lifts compacted dirt out of the corners. Step three: scrub with an old toothbrush along the track and into the corner notches. Step four: wipe out with a microfibre cloth folded into the track shape, then dry completely. Sliding aluminium frames need a separate sugar-soap wipe, and the rubber seals get a quick clean with a damp cloth — never solvent, which perishes the rubber and triggers a replacement charge. Fly screens lift out and rinse in the shower with a soft brush; a dirty fly screen is an instant flag. Glass itself should be cleaned with a microfibre and a 10% white vinegar solution, finished with a dry microfibre in a single direction so streaks don't catch the late-afternoon sun during inspection. Don't forget the inside of the security screens on the front and back doors — agents lift them open and check. A quick photo of every cleaned window, taken with the camera focused into the track, is irrefutable evidence if the agent later claims the windows weren't done.
