Preventing Rust on Glass Pool Fence Spigots
March 25, 2025
Glass pool fencing is a popular choice in Sydney for its clean look, durability, and minimal maintenance. However, a common concern among homeowners is whether the metal spigots used to secure the glass are prone to rust. While most spigots are made from corrosion-resistant materials, long-term exposure to the elements, pool chemicals, and installation conditions can still lead to wear over time.
This article outlines the typical causes of rust and corrosion on glass pool fence spigots. It also provides practical tips on prevention and long-term care—helping those with glass fencing in Sydney understand how to keep their pool area looking its best and functioning safely.
Glass pool fence spigots are typically made from corrosion-resistant metals like stainless steel or aluminium, chosen for their durability and low maintenance. Stainless steel, in particular, contains chromium, which forms a thin oxide layer that helps prevent rust. However, no metal is entirely immune to environmental wear.
Over time, exposure to salt air, humidity, and chemicals such as chlorine can degrade this protective layer, potentially leading to corrosion—even in high-quality materials. Understanding how different materials perform under these conditions is key to choosing and maintaining long-lasting spigots.
The durability and performance of pool fence spigots depend largely on the materials used in their construction. Since these components are constantly exposed to moisture, chemicals, and changing weather conditions, manufacturers typically select metals that offer both strength and corrosion resistance.
Stainless steel is the most widely used material for glass pool fence spigots due to its excellent resistance to rust and corrosion. Marine-grade stainless steel—such as 316 or 2205 duplex—is particularly effective in pool environments:
Aluminium spigots are a lighter-weight alternative, naturally forming a protective oxide layer that helps prevent corrosion. While resistant to rust, aluminium may not perform as well as stainless steel in high-chloride or salt-rich environments, and is generally less durable under prolonged exposure to harsh poolside conditions.
Even though most glass pool fence spigots are made from corrosion-resistant metals, they aren’t immune to rust. Understanding the real-world conditions that lead to corrosion helps you identify risks early and take steps to protect your investment.
Chlorine is essential for keeping pool water clean, but it's a corrosive substance. When chlorine-laden water splashes onto the spigots or evaporates into the air, it leaves behind residues that slowly break down protective layers—especially around the base or joints where water tends to collect.
Tip: Spigots placed closer to the pool edge or in areas with poor drainage are more prone to this kind of exposure.
If you live near the coast, your spigots are exposed to salt carried by the wind. Salt particles settle on surfaces and draw in moisture from the air, forming a salty film that can rapidly accelerate corrosion, even on marine-grade stainless steel.
Tip: Spigots exposed to wind or positioned near landscaping that traps moisture are particularly vulnerable.
Rain, humidity, and temperature fluctuations all play a role. Acid rain (common in urban areas) can be mildly corrosive, and regular wet-dry cycles cause metals to expand and contract, weakening protective finishes. Long periods of humidity or shaded areas where moisture doesn’t dry out can also hasten rust formation.
Spigots often have protective coatings like electropolishing or powder coating. However, any scratches during installation, knocks from pool furniture, or wear from foot traffic can expose raw metal beneath the coating. Once this happens, corrosion can spread quickly from a small point.
Tip: Always inspect spigots after installation or high-use periods like summer to catch damage early.
Preventing rust doesn’t have to be difficult. With a bit of routine care and awareness of your pool’s environment, you can significantly extend the lifespan of your glass pool fence spigots.
Not all stainless steel is the same. If your pool is in a coastal or high-humidity area, 316 or 2205 duplex stainless steel offers better resistance to salt and stress corrosion than lower grades like 304.
Best for:
A quick rinse with fresh water helps remove chlorine, salt, and dust particles that would otherwise settle and start breaking down protective finishes.
Practical tip: Use a garden hose to rinse the spigots once a week—especially after heavy pool use or windy coastal days.
Use a soft cloth or sponge with warm water and a mild detergent. Avoid abrasive cleaners, steel wool, or acidic products like bleach or hydrochloric acid—they can damage the surface and strip protective coatings.
Simple method:
If you notice rust stains or discolouration, treat them early to prevent deeper corrosion. White vinegar is a safe, non-toxic option for small areas. For tougher spots, use a rust remover made specifically for stainless steel.
Steps:
Check spigots every few months for signs of:
Addressing these early prevents small issues from turning into safety concerns.
Unbalanced pool water—with high or low pH levels—can intensify corrosion. The ideal pH for pool water is typically between 7.2 and 7.6. High chlorine levels should also be monitored, especially in heated or saltwater pools.
Test your water regularly and adjust with appropriate pool chemicals to reduce long-term stress on surrounding metal fixtures.
Avoid allowing water to sit at the base of the spigots. Ensure the area around each spigot drains well and is exposed to airflow to help the metal dry naturally.
Pro tip: Keep landscaping trimmed and avoid placing moisture-retaining pots or mulch near the base of the fencing.
Beyond day-to-day care, keeping your spigots rust-free over the long term requires some occasional attention to detail and awareness of how they perform in the environment over time. These steps focus on preserving function, appearance, and durability—especially in coastal areas like Sydney where exposure to salt air is ongoing.
While stainless steel is naturally corrosion-resistant, applying a protective sealant or polish every six months adds an extra layer of defence. Look for products specifically formulated for marine-grade stainless steel, and always clean the spigots before application to ensure proper adhesion.
This is especially helpful in high-exposure settings, such as beachfront properties or pool areas with frequent chemical use.
Over time, even well-maintained spigots can develop signs of fatigue or surface wear. Check for:
Catching these signs early allows for simple correction rather than full replacement.
As part of your seasonal or annual pool care, inspect the spigot fittings, fasteners, and base plates for movement or instability. Loose components may allow moisture to seep in and accelerate hidden corrosion. Use the correct tools to tighten any fittings, being cautious not to overtighten and strip threads.
If components show signs of excessive wear, consult your original supplier or a pool fencing professional for advice on part replacement.
While routine maintenance can go a long way, an annual check by a professional—particularly in high-risk environments—can help identify less obvious issues such as internal corrosion, faulty installation, or stress damage from temperature shifts or pool movement.
Professionals can also recommend product-specific care approaches based on the material and finish of your existing spigots.
If your pool fencing has been in place for many years or the surrounding environment has changed (e.g. added landscaping, higher pool usage, or increased chlorine levels), it may be worth reassessing whether your current spigots are still fit for purpose.
Modern spigots often come with better corrosion-resistant alloys, improved finishes, and sleeker mounting systems designed for longevity. Upgrading when needed can help avoid more costly repairs down the track.
Keeping glass pool fence spigots in top condition is a key part of maintaining both the safety and visual appeal of your pool area. While marine-grade stainless steel offers excellent resistance to rust, long-term exposure to chlorine, salt air, and changing weather conditions can still lead to corrosion over time.
By understanding the factors that contribute to rust and taking simple, proactive steps—such as routine cleaning, applying protective treatments, and conducting regular inspections—you can greatly extend the life of your spigots. With the right care, your glass fencing will remain secure, functional, and visually appealing for years to come.
