Soap scum isn’t confined to bathtub rings and dirty shower walls. If you maintain a mirror on your shower or splash the one over the sink when you wash your face, soap scum may build up on the glass. This oily film is a combination of soap residue, mineral deposits in water, bacteria, dirt, and the oils you wash your skin off. Luckily, even heavy soap scum comes off a mirror having a tiny scrubbing and cleanser.
Vinegar
Pour 1/4 cup white vinegar and 1 cup water in a spray bottle. Shake the bottle to mix.
Spray the mirror generously using the vinegar solution and allow it to sit for five minutes.
Wipe the mirror clean with a paper towel.
Spray some of the vinegar solution on a soft toothbrush and scrub around the inside of the mirror frame, in which the frame meets the glass.
Polish the mirror with a piece of crumpled newspaper to eliminate streaks.
Ammonia
Open the windows and turn on the ventilation fan in the bathroom. Wear a set of rubber gloves.
Mix 1/2 cup ammonia and 1/2 cup water in a spray bottle. Shake the bottle to mix.
Spray the ammonia solution on the mirror and then wipe it off with a paper towel. Repeat this step if any soap scum stays.
Spray some of the ammonia solution on a soft toothbrush and scrub across the inside of the mirror frame, in which the frame meets the glass.
Polish the mirror with a piece of crumpled newspaper to eliminate streaks.
