If your glass pool fence or balcony balustrade always looks streaky, cloudy, or watermarked no matter how often you clean it, you’re not imagining it. Outdoor glass is constantly exposed to the elements. Salt spray, hard water, chlorine, dust, and bird droppings all contribute to a surface that no longer sparkles, no matter how much you wipe.
Even if your glass has been treated with a protective coating like EnduroShield, a bit of maintenance is still needed to keep it performing at its best. In this guide, you’ll learn how to clean your glass the right way using professional tools, simple products, and techniques that deliver a clear result every time.
Why It’s Worth Maintaining
Outdoor glass is more vulnerable than it looks. Without regular care, it can become stained, etched, or permanently damaged. A consistent cleaning routine helps:
-
Keep the surface clear and streak-free
-
Prevent build-up from salt, minerals, and pool chemicals
-
Maintain the condition and appearance of the glass
-
Maximise the lifespan of any protective coating

Rinse the Glass
Before you begin cleaning, rinse the glass thoroughly using a garden hose on a low-pressure setting. This removes loose dust, dirt, bird droppings, and salt that could scratch the surface if left behind.
This step applies to all outdoor glass, including pool fencing, balcony balustrades, windows, and sliding doors.
Clean and Dry the Glass Using the Window Washer and Squeegee
For best results, use the EnduroShield Professional Squeegee and Window Washer. This method helps you achieve a streak-free finish while protecting your glass and any coating applied.
Step 1: Prepare Your Cleaning Solution
Fill a rectangular bucket with cold water and add a small amount of mild dishwashing detergent, such as Morning Fresh. Avoid hot water or harsh cleaners, as these may damage the coating.
Step 2: Use with the Window Washer
Dip the washer head into the soapy water and apply it across the glass surface. Rub gently and evenly to lift away dirt, grime, and water spots.
Step 3: Squeegee Before the Detergent Dries
Use the squeegee to remove the water before it starts to dry. Start at the top corner of the glass and move from side to side, overlapping slightly as you work your way down.
Step 4: Dry the Edges
Once the panel is clean, use a dry microfibre cloth to wipe around the edges and remove any remaining water.
Make Cleaning Easier with EnduroShield Protection
If you'd prefer to clean less often and spend less time scrubbing, EnduroShield can help. It’s a clear, long-lasting coating that bonds to the glass and helps repel water, oils, dirt, and mineral deposits.
Why it’s Worth Applying:
-
Reduce cleaning time by up to 90%
-
Helps prevent staining and etching
-
Keeps your glass looking cleaner for longer
If your glass hasn’t been treated yet, the Glass Treatment Large Super Bundle includes everything you need to clean and protect your outdoor glass.
If your glass is already protected, the Cleaning Accessory Bundle includes a coating-safe cleaner and microfibre cloths designed to maintain it.
What If Your Glass Already Has Marks?
If your glass has white marks, hard water stains, or a hazy appearance that doesn’t come off with cleaning, restoration may be needed.
Use a glass restoration polish to remove mineral damage and bring the clarity back. Once restored, the glass can be protected with EnduroShield to help prevent future damage.
