- Avoid Direct Sunlight: Cleaning windows in direct sunlight can cause the cleaning solution to dry too quickly, leading to streaks. Choose a cloudy day or work in the shade if possible.
- Use a Clean Squeegee: Ensure your squeegee blade is clean and free of debris. A dirty squeegee can scratch your glass and leave streaks.
- Dry the Squeegee After Each Pass: Wipe the blade with a cloth after each stroke to prevent drips and streaks.
