Essential Tools for Cleaning Outside Windows – By Double Glazing Experts

Before tackling your exterior windows, it’s essential to get the proper equipment and tools to do the job successfully.

You’ll need:

  • Squeegee with a rubber blade 
  • Soft sponge or microfibre cloth 
  • Sturdy bucket (for your cleaning mixture) 
  • Ladder (if necessary)
  • Lint-free cloths 
  • Window-cleaning solution 

We always recommend investing in a good-quality squeegee can make all the difference compared to cheaper items, helping you achieve a professional finish without the cost of hiring in a window cleaner.

The Best Cleaning Solutions for Exterior Windows

There are plenty of commercial window cleaners on the market for you to choose from.

However, homemade methods can work just as well.

If you do decide to go for a homemade solution, try to use distilled water for a spotless finish. Avoid cleaning using tap water and regular bottled water, as these contain minerals that can cause streaks.

Water and Dish Soap

One popular method is to mix warm distilled water with a tiny amount of washing-up liquid. This creates a soapy water solution that is perfect for window cleaning.

Water and Vinegar

Your exterior windows can be prone to stubborn dirt and grime.

For a tougher cleaning solution, creating a mixture of equal parts white vinegar and warm water can help cut through the grime to get your windows looking their best.

Step-by-Step Process to Clean Outside Windows

Cleaning your outside windows can take time, but with the right patience and preparation, you can achieve sparkling clean windows that will look great for the season.

1. Prepare the Area

If you’re using a ladder, make sure it’s securely positioned on level, stable ground before you climb.

Begin by brushing away any loose dirt or cobwebs from both the windows and surrounding frames with a soft brush or cloth. This prevents you from scratching the glass as you clean.

For cleaning both inside windows and outside windows, we advise choosing a cloudy day if possible.

Direct sunlight can cause you cleaning solution to dry too quickly which results in streaks.

2. Apply Your Cleaning Solution to Wash the Window

Fill your bucket with your chosen cleaning solution and use your sponge to thoroughly wet the entire window surface.

When dealing with particularly dirty windows, let the solution sit for a few minutes. This extra time helps break down stubborn dirt and grime, making the next steps much easier.

3. Scrub as Needed

Gently scrub windows with persistent marks or built-up grime.

Make sure not to use anything abrasive that might scratch the glass and damage the window.

Corners and edges of your windows need the most attention, as these areas tend to collect the most dirt over time.

4. Squeegee Technique For a Streak Free Finish

The squeegee is your best friend for a professional finish and remove excess water.

There are two ways to use the squeegee:

Option 1: Straight Strokes

Start at the top of the window and pull the squeegee down in a smooth, horizontal motion. Work your way across the window, slightly overlapping each stroke to prevent smudging. Remember to wipe the blade with a lint-free cloth after every pass.

Option 2: The S-Pattern

This technique involves moving the squeegee in one continuous S-shaped motion from top to bottom. It takes a little practice, but it delivers an excellent streak-free finish.

5. Dry the Edges

Use a clean, dry microfibre cloth to wipe any remaining water from the edges of the window and the frame.

This final step prevents water spots from forming as droplets to keep your window dry. This protects your window frames from potential water damage over time.

We always recommend using microfibre cloths instead of paper towels, because paper towel fibres can cause annoying marks that will ruin your hard work.

Window Cleaning for High or Hard-to-Reach Windows

Upper floor windows are harder to reach. However, there are many different ways to clean outside windows safely and effectively.

Instead of using a ladder, there is a range of extendable tools on the market to help you reach high windows without leaving the ground.

If you do need a ladder, always position it on stable, level ground. Having someone stand at the bottom of the ladder adds an extra layer of safety.

For windows that are particularly high, you might want to consider investing in a magnetic window cleaner. This allows you to clean both sides of the glass simultaneously. Although it is unlikely to give you as good a finish as using a squeegee and a dry cloth.

Maintaining Clean Windows Year-Round

Once you’ve got your windows sparkling clean, a bit of regular maintenance can keep them looking good for longer periods.

Dust window frames and sills regularly to prevent build-up that can transfer to the glass during rainy weather. A quick rinse with a garden hose every few weeks can remove light dirt before it becomes stubborn grime and needs more maintenance.

We recommend planning for a thorough cleaning at least twice a year, typically during spring and autumn. This schedule helps keep your windows in top condition and maximises the natural light flowing into your home throughout the year.
