Keeping your windows clean is essential—not just for appearances, but also for preserving the quality of your glass and letting natural light brighten up your home or office. Many Dublin residents and business owners try their hand at DIY window cleaning to save time and money. However, without the right tools, techniques, or understanding of common pitfalls, DIY efforts can sometimes do more harm than good.

At Shiny Bright Windows, we’ve seen it all—scratched glass, streaky panes, hard water stains, and even accidental damage to window frames. That’s why we’ve created this in-depth guide to help you recognize and avoid the most common mistakes people make during DIY window cleaning in Dublin.



1. Using the Wrong Cleaning Products

One of the biggest mistakes homeowners make is using the wrong type of cleaning solution. Many reach for general-purpose cleaners or make their own using vinegar or dish soap. While these may work on some surfaces, they can often leave behind streaks, residues, or even damage your windows.

What to Use Instead:

  • Use a dedicated glass cleaner that's ammonia-free.

  • Avoid harsh chemicals that can damage seals or frames.

  • Consider eco-friendly solutions, especially important for Dublin homes near nature reserves or gardens.


2. Cleaning Windows on a Sunny Day

You might think a sunny day is the perfect time to clean your windows—it’s bright, dry, and warm. However, this is a trap that leads to frustrating results.

Why It's a Problem:

  • Sunlight causes the cleaning solution to dry too quickly.

  • This results in streaks and visible marks that are hard to remove.

Tip:

Choose a cloudy, overcast day for window cleaning. Dublin's climate offers plenty of those—take advantage!


3. Using Old or Dirty Tools

Many people reuse old towels, t-shirts, or worn-out squeegees to clean their windows. Unfortunately, this is one of the fastest ways to ruin your efforts.

What Happens:

  • Old rags leave behind lint and fibers.

  • Dirty tools can scratch the glass or spread grime instead of cleaning it.

Use Instead:

  • A clean microfiber cloth or a high-quality squeegee.

  • Replace or clean your tools regularly for the best results.


4. Ignoring the Window Frames and Sills

A sparkling clean window pane surrounded by a dusty, grimy frame just doesn’t cut it. Many DIY window cleaners forget to clean the frames, tracks, and sills.

Why It Matters:

  • Dirt and moisture in frames can lead to mould and wood rot.

  • It affects the overall appearance and cleanliness of your window.

Pro Tip:

Start by vacuuming or wiping down the frame and sill before tackling the glass.


5. Using Too Much Water

More water doesn't mean a cleaner window. In fact, using too much water, especially in traditional sash windows found in many Dublin homes, can lead to damage.

The Risks:

  • Water can seep into the frames, causing swelling or damage to paint.

  • Excess water is hard to manage, leading to streaks and dripping.

Solution:

Use a damp, not soaking, cloth or sponge. Control the amount of liquid applied to each pane.


6. Not Removing Dust and Cobwebs First

Jumping straight into wet cleaning without removing loose dirt or cobwebs is a rookie error. The result? You end up smearing dirt across the surface.

Before You Begin:

  • Dust the window with a dry cloth, soft brush, or vacuum.

  • Remove cobwebs and debris from corners and sills.


7. Not Rinsing Properly

Rinsing is an often-overlooked step in the DIY process. If you're using a homemade solution or soap, you need to rinse it off properly.

What Happens If You Don't:

  • Soap or chemical residues dry on the glass, leaving unsightly marks.

  • Over time, this buildup becomes harder to remove.

Always:

Use clean water for rinsing, and make sure to dry the window with a squeegee or lint-free cloth.


8. Using Paper Towels

It’s tempting to grab paper towels for a quick clean, but they’re a bad choice.

Why You Shouldn’t:

  • They leave lint and tiny fibers on the glass.

  • They can cause streaks, especially if the towels are too absorbent or disintegrate easily.

Use Instead:

  • High-quality microfiber cloths.

  • A squeegee for a streak-free finish.


9. Cleaning Too Quickly

If you rush the job, you’re likely to miss spots or leave behind streaks.

Take Your Time:

  • Clean in sections—one pane at a time.

  • Pay attention to detail. Proper technique always wins over speed.


10. Skipping Regular Maintenance

A once-a-year deep clean might seem sufficient, but letting dirt, rain stains, and pollution build up can damage your windows over time.

What We Recommend:

  • Clean your windows every 6–8 weeks.

  • If you live near the coast or a high-traffic area in Dublin, consider cleaning more often.


11. Attempting High Windows Without Proper Equipment

DIYers often try to clean high windows using chairs, ladders, or by stretching dangerously.

This Is a Safety Risk:

  • Falls from height are a serious hazard.

  • Damaging the window or your roofline is another risk.

Instead:

Call a professional like Shiny Bright Windows. We use specialized equipment and safety practices to clean high or hard-to-reach windows with zero risk to you.


12. Forgetting to Check the Weather Forecast

You spend hours cleaning your windows, and then—boom!—Dublin’s unpredictable rain showers return and undo all your hard work.

What to Do:

  • Always check the Met Éireann forecast before planning your window cleaning day.

  • Avoid windy days too, as dust can quickly re-stick to damp surfaces.


13. Not Wearing Gloves or Protective Gear

Window cleaners often overlook their own safety during DIY tasks.

Risks Include:

  • Skin irritation from cleaning solutions.

  • Scrapes or splinters from wooden window frames.

  • Exposure to mould or allergens.

Simple Fix:

Wear rubber gloves, long sleeves, and eye protection if needed.
