Final answer:
For window touch-ups with a blue handled cleaning pad, spray the glass cleaner directly onto the window to prevent streaks and ensure even coverage. The pad should not be oversaturated. Follow safety guidelines by wearing appropriate protective gear.
Step-by-step explanation:
When touching up windows using a blue handled window cleaning pad, it is recommended to spray the glass cleaner directly onto the window rather than the pad. This method helps to avoid over-saturating the pad, which can lead to streaks, and ensures an even distribution of the cleaner on the glass surface. Glass cleaners typically contain alcohols like ethanol or isopropyl, surfactants for grease dissolution, and sometimes small amounts of ammonia, which make them effective for cleaning without the need for rinsing and achieving a streak-free finish.
Always follow safety procedures such as using gloves, goggles, and safety aprons when handling glass cleaning chemicals or when cleaning up broken glass with a dustpan and broom, instead of with bare hands. For non-disposable cleaning materials like the window cleaning pad, it is important to ensure they are kept clean and free of debris, as accumulated dirt can scratch surfaces, especially delicate ones like optical components.
