Inside Window Cleaning
First things first, let's talk about what you'll need. For indoor window cleaning, a few key tools can make all the difference:

Microfibre Cloth: This is a game-changer. Microfiber cloths don't leave lint behind and are great at capturing dust and smudges without scratching your windows.


Squeegee: Perfect for streak-free finishes, a good squeegee can save you a lot of time and effort.


Window Cleaning Solution: You can either buy a commercial cleaner or make your own with a mixture of water and vinegar. The vinegar helps break down grime and leaves a nice shine.

Step-by-Step Guide to Cleaning Windows from the Inside

Start with the Frame: Dust the frame and sill before you start on the glass. This prevents any dirt from the frame from muddying your freshly cleaned windows.


Apply the Cleaning Solution: Spray your cleaning solution onto the window. Don't be shy, but also, don't soak it.


Wipe in a Z-Pattern: Using your microfiber cloth, start at the top and move in a Z-pattern. This motion is effective for covering the entire surface without leaving streaks.


Squeegee for a Finish: Use a squeegee from top to bottom for that final touch. This helps remove any remaining solution and leaves your window shining.

Professional Insights for Streak-Free Results

The Right Time Matters: Cleaning windows on a sunny day might seem ideal, but direct sunlight can cause the cleaning solution to dry too quickly, leaving streaks. A cloudy day is actually your best bet.


Detail with a Cotton Bud: For those hard-to-reach corners, a cotton bud can be your secret weapon. It's great for picking up that last bit of dirt.

Tips for Indoor Window Cleaning

Dealing with Stickers or Decals: If you have kids, you might find stickers on the windows. A little bit of oil (like eucalyptus or cooking oil) can help peel them off easily.


DIY Cleaning Solution for Stubborn Stains: For tougher stains, add a drop of dish soap to your vinegar and water solution. It cuts through grease and grime effectively.

Outside Window Cleaning
When it comes to cleaning your windows from the outside, you're dealing with a whole different set of challenges compared to the inside. Weather elements, especially here in Australia, can really put your windows through the wringer. Think about the coastal air carrying salt, the harsh sun, or even the occasional stormy weather – they all leave a mark. But don’t worry, because understanding these challenges is the first step in overcoming them.
Safety First
Let's talk safety – it's absolutely crucial, especially when dealing with the exterior of your home. For those of you in multi-storey houses, this part's especially for you. Always ensure you have a stable, secure ladder. If you're not comfortable or if it's too high, it might be time to call in the professionals. Remember, no window is worth risking your safety.
Professional Techniques for Sparkling Results
Now, onto the fun part – the cleaning process. Professional cleaner, like us at Gold Coast Clean & Sheen, often use a squeegee for outdoor windows. Why a squeegee, you ask? Well, it efficiently removes water and cleaning solution, reducing streaks and allowing for a quicker drying time. Plus, it's quite satisfying to see that clear path being created with each swipe.
Start by gently hosing down the window to remove any loose dirt or debris. Then, using a soft brush with a mild detergent solution, gently scrub the window. This step is essential for loosening any stubborn grime. Next, take your squeegee and with confident, even strokes, clear off the water and soap. Don't forget to wipe the edges with a clean, dry cloth to prevent drips!
The Impact of Coastal Climate on Your Cleaning Routine
For those of you living near the coast, you might notice your windows need cleaning more often. That's because the salt in the sea air can leave a residue over time. Regular cleaning not only keeps your windows looking great but also helps in protecting them from the corrosive nature of salt.
Common Mistakes in Window Cleaning
It's like this - even with the best intentions, a few slip-ups can happen, and they can keep your windows from being as shiny as you'd like. But don't worry, we're here to guide you through these and help you correct them like a pro.
1. Choosing the Wrong Time of Day

Mistake: Cleaning your windows under the harsh midday sun.


Why It's a Problem: The heat causes cleaning solutions to dry too quickly, leaving unsightly streaks.


The Fix: Aim for an early morning or late afternoon clean. Cooler temperatures mean slower drying, giving you a streak-free finish.

2. Using the Wrong Cloth

Mistake: Grabbing any old rag or towel to dry your windows.


Why It's a Problem: Some materials can leave lint or not absorb water well, leading to streaks or residue.


The Fix: Use a microfibre cloth or a squeegee. They're super absorbent and lint-free, making them perfect for a crystal-clear finish.

3. Overlooking the Details

Mistake: Ignoring the window edges and frames.


Why It's a Problem: Dirt accumulates in these areas and can run onto the glass, undoing your hard work.


The Fix: Always start by wiping down the frame and edges. This prevents any dust or dirt from marring your beautifully cleaned glass.

4. Using Too Much Cleaning Solution

Mistake: Going overboard with the spray or soap.


Why It's a Problem: Excess solution can leave residue and streaks, making windows look cloudy.


The Fix: Less is more here. A few spritzes of your cleaner are usually enough. It's all about the technique, not the quantity.

5. Ignoring Weather Conditions

Mistake: Deciding to clean your windows on a rainy or extremely windy day.


Why It's a Problem: Rain can undo your cleaning efforts, and wind can blow dust and debris onto your wet windows.


The Fix: Check the forecast before you start. A calm, dry day is your best bet for keeping those windows sparkling.

Going Beyond the Basics
Tackling Hard Water Stains

The Challenge: Hard water stains are caused by mineral deposits left behind when water evaporates. They can be quite persistent and tough to remove if you don't know the right technique.


The Solution: To effectively tackle these, you'll need a mixture of vinegar and water. Vinegar is a natural acid that breaks down the mineral deposits, making them easier to wipe away.


How to Do It: Mix one part white vinegar with one part water in a spray bottle. Apply it liberally to the stained area and let it sit for a minute. Then, gently scrub with a soft brush or cloth, and rinse with clean water. This method is safe, environmentally friendly, and highly effective.

Removing Bird Droppings

The Challenge: Bird droppings can be not only unsightly but also acidic, which means they can damage the glass if not cleaned properly and promptly.


The Solution: The key here is to soften the droppings before attempting to remove them. This prevents scratching the glass.


How to Do It: Soak a cloth in warm, soapy water and place it over the dropping for several minutes. This softens the waste, allowing you to gently wipe it away without harming the glass. Finish by cleaning the area with your regular window cleaning solution.
