Common mistakes when cleaning glass and mirrors

Cleaning glass and mirrors can be tricky, and common mistakes can easily ruin your hard work. Here are some frequent issues and how to avoid them:

  1. Smearing/Streaks: Often caused by using the wrong type of cloth or paper towel, which leaves lint or fibres behind. (To prevent streaks, use microfibre cloths that trap dirt effectively.)
  2. Cloudy or Hazy Appearance: Residue from hard water or cleaning chemicals can leave a cloudy film on surfaces. (Remove leftover residue with distilled water, thoroughly drying with a microfibre cloth.)
  3. Fingerprints & Grease: These can be stubborn to remove without the right cleaning products. (Make sure to use specialised glass and mirror cleaning chemicals.)
  4. Scratches & Abrasions: Harsh cleaning tools and improper techniques can scratch glass and mirrors. (Always use microfibre cloths or gentle sponges for cleaning.)

Essential tools for streak-free cleaning

Having the right tools and products makes all the difference when it comes to achieving streak-free results on glass and mirrors. Below, we have compiled a short list of recommended window and mirror cleaning products. 

What should you not use to clean windows and mirrors?

It’s essential to avoid certain products that can leave streaks and damage mirror and glass surfaces. Here are some chemicals you should not use:

  • Ammonia-based cleaners: if not properly diluted or placed in direct sunlight, ammonia cleaners can cause streaks
  • Harsh abrasives: Avoid using harsh tools like scrub brushes and galvanised scourers, as these can scratch and damage surfaces
  • Cleaners with additives: Many commercial cleaners include additives such as soaps, scents, and dyes, which can leave streaks or residues on glass surfaces. 
  • Paper towels: Commonly used for cleaning glass in the past, these can leave lint and fibres behind. 

how often should you clean mirrors and glass surfaces?

Determining how often to clean mirrors and glass surfaces depends on location and usage.
 
Mirrors in high-traffic areas like bathrooms benefit from weekly cleaning to effectively manage fingerprints and dust. Those used heavily may require cleaning every few days, while less-used mirrors can be cleaned bi-weekly or monthly.
 
Indoor glass surfaces, such as windows and tabletops, should also be cleaned weekly to remove dust and fingerprints. Depending on weather and surrounding conditions, outdoor windows may need less frequent cleaning, typically seasonally or bi-annually. Regular spot cleaning is essential for mirrors and glass to address any marks and promptly maintain their clarity.
 
By establishing a cleaning routine tailored to your specific needs, you can ensure mirrors and glass surfaces remain clear and enhance the overall appearance of your home or workspace.
 

Step-by-step guide on how to clean glass

Cleaning glass surfaces like windows, glass tabletops, and glass furniture requires special attention to detail for a streak-free finish. Here’s a step-by-step guide:

  1. Prepare: Gather all necessary supplies and remove any obstacles to prevent accidents.
  2. Spray: Use a specialised glass cleaner, spraying the solution 6-8 inches from the surface. Avoid over-spraying the glass.
  3. Wipe: With a microfibre cloth, wipe the glass in straight, overlapping strokes. Start from the top and work your way down to prevent drips.
  4. Polish: After wiping, use a microfiber cloth to polish the glass surface in circular motions, removing any remaining streaks.

For stubborn spots or dried-on dirt, respray the area and let the solution sit for a few seconds before wiping and polishing. Inspect the glass surface from different angles and lighting to ensure it’s free of streaks and smudges.
