Final answer:
The correct use of glass cleaner is to clean mirrors, applying with a spray or cloth and wiping down with a soft, lint-free duster for a streak-free finish.
Step-by-step explanation:
The correct answer to the question is SSM a) We use glass cleaner to clean mirrors. Glass cleaners typically consist of alcohols like ethanol or isopropanol, surfactants for dissolving grease, and sometimes small amounts of ammonia, which all help to achieve a streak-free shine on glass surfaces. These cleaners are specially formulated to handle light dirt and are not intended for heavy-duty cleaning or surfaces other than glass. Applying these cleansers to glass surfaces can be done directly by spraying or with a cloth, and then the surface is wiped with a soft, lint-free duster to prevent streaks. Special purpose cleaners are designed for specific surfaces, and using the correct one is essential for effective cleaning without causing damage.
