Why Mirrors Get Dirty Fast

Mirrors attract fingerprints, water spots, dust, and toothpaste splatter — especially bathroom mirrors. The frustrating part is that wiping with a cloth often leaves streaks that look worse than the original dirt. After 15 years of installing mirrors across Bhayandar and Mira Road, we have seen every kind of mirror damage — and most of it is caused by incorrect cleaning. Here is the right way to do it.

What NOT to Use on Mirrors

  • Do not use acidic cleaners (vinegar, lemon juice, bathroom acid cleaners) — these attack the silver backing of the mirror and cause dark spots that cannot be fixed
  • Do not spray directly on the mirror — liquid seeps into the edges and damages the silver backing from behind, causing black edge spots
  • Do not use rough scrubbers — they scratch the glass surface permanently
  • Do not use newspaper — an old myth, newspaper ink smears on mirrors

The Right Way to Clean a Mirror

For Daily Cleaning

  1. Spray a small amount of glass cleaner (like Colin) onto a microfiber cloth — not directly on the mirror
  2. Wipe in a circular motion from top to bottom
  3. Buff with a dry microfiber cloth to remove any streaks

For Stubborn Spots

Mix one part isopropyl alcohol with one part water. Apply to the cloth and gently rub the spot. Alcohol evaporates cleanly without leaving residue.

For Water Spots (Bathroom Mirrors)

Hard water leaves calcium deposits that look like cloudy white spots. Use a commercial hard water remover or a paste of baking soda and water — apply, let sit for 2 minutes, then wipe gently with a damp cloth.

Protecting the Mirror Edges

The black spots that appear on mirror edges are caused by moisture reaching the silver backing. To prevent this:

  • Keep the bathroom well-ventilated
  • Do not hang mirrors in areas where water directly splashes on them
  • For frameless mirrors, apply clear silicone sealant along the bottom edge where it meets the wall

How Often to Clean

  • Bathroom mirror — wipe down every 2 to 3 days
  • Bedroom and dressing mirror — once a week
  • Decorative and antique mirrors — monthly with a dry microfiber cloth only

When to Replace Your Mirror

If your mirror has black spots spreading from the edges, a cloudy centre that does not clean off, or visible cracks, it is time to replace it. At Amar Glass Studio, we can replace just the glass in your existing frame — saving the frame cost.
