Cleaning windows should start by clearing dry dust and debris in the window tracks to avoid forming mud when adding water. Glass cleaning requires identifying if the material has special coatings and following the principle of from inside to outside and frame before glass. It is strictly forbidden to dangerously lean out; ensure all operations are completed within the safe range indoors.
Should I clean the glass first or the window tracks first?
Handling dry dust and loose debris on the window frame and tracks before cleaning the glass helps prevent clean surfaces from getting dirty again. Do not drag sand particles with a wet cloth, otherwise the frame surface may be scratched.
- Check if the windows can be opened and closed safely and if the glass has cracks
- Vacuum up loose dust in window tracks
- Use a slightly damp cloth and soft brush to handle corners
- Wipe glass in sections and wipe the edges dry
- Check if the surface of drainage holes is covered by debris
Are white marks definitely because it hasn't been cleaned thoroughly?
White marks may come from water stains, renovation residue, cleaning agents, or damage to the glass surface. Confirm if it is a coating, film, or special glass first, then choose a method.
Strong acids, blades, and abrasive tools can permanently damage the surface. If there is no improvement after testing, do not constantly increase the force; let glass or window professionals make the judgment.
Can window tracks be washed with water directly?
Pouring large amounts of water may push mud and dust into drainage locations or spill into the room. Using a small amount of water, a slightly damp cloth, and vacuuming debris is easier to control.
Clogged drainage holes, water leakage, or aged frames may involve repairs; cleaning surface debris does not mean the entire drainage structure is fixed.
How to handle high-rise exterior windows in Hong Kong?
Only handle locations that can be touched safely from inside; do not step on window sills, lean out the window, or extend equipment to places where it might fall. Fly screens, window grilles, and anti-fall devices should not be removed at will.
When inquiring, take panoramic photos of windows and their opening method, and confirm the interior/exterior window scope, working methods, and safety arrangements with the service provider. Do not assume that high-altitude work is included under the general name of home cleaning.
What details should I look at during acceptance?
Observe wipe marks, edge water spots, and window track dust under different light, and compare them separately from original scratches or corrosion. Before and after photos should use similar positions and lighting; do not judge based solely on reflection strength.
