How to NOT leave streaks behind…
To clean windows without leaving streaks, you can follow these steps:
Dust or wipe down the window frame and sill to remove any loose debris.
Mix a solution of mild soap and water in a bucket or use a solution of white vinegar and water.
Use a squeegee and a soft-bristled brush or a microfiber cloth to clean the windows, starting at the top and working your way down.
Wipe the squeegee blade with a microfiber cloth or a lint-free cloth after each pass to prevent streaks.
Dry the windowsill with a microfiber cloth or a lint-free cloth to prevent water spots.
Clean the windows on a cloudy day, as direct sunlight can dry the cleaning solution too quickly, leaving streaks.
It is also important to use a clean, lint-free cloth or a microfiber cloth for drying the windows. If you see any remaining streaks, you can use a lint-free cloth or a newspaper to wipe them away.
