Corrosion not only damages the faucet but also leads to water contamination. Follow simple steps from this guide to effectively prevent corrosion on the faucet. By preventing corrosion, you can extend the life of the faucet and its functionality.

Types of Faucet Corrosion

1. Uniform corrosion: This type of corrosion occurs evenly across the surface of the faucet. It is usually caused by exposure to aggressive water or chemicals. Uniform corrosion often results in a dull and pitted appearance of the faucet.
2. Galvanic corrosion: Galvanic corrosion occurs when two dissimilar metals come into contact in the presence of an electrolyte, such as water. The more reactive metal corrodes, while the less reactive metal remains relatively unaffected. This type of corrosion is commonly seen in faucets where different metals are used in their construction, such as brass valves with steel handles.
3. Crevice corrosion: Crevice corrosion takes place in confined spaces or crevices where water and contaminants can accumulate, such as the gaps between faucet components or around seals. The trapped moisture creates an ideal environment for corrosion to occur, leading to localized damage.
4. Pitting corrosion: Pitting corrosion appears as small, localized pits on the surface of the faucet. It is often caused by the presence of aggressive chemicals or water with high chloride content. Pitting corrosion can weaken the structural integrity of the faucet and cause leaks over time.

What Causes Faucet Corrosion?

Water Quality

The quality of water depends on what types of minerals are present in the water. When in water magnesium and iron are found in high quality, they will react with the metal of the faucet and create corrosion.

Water with low pH levels also causes corrosion. This type of water is indicating acidity and it is corrosive to metal.

Chemical Exposure

When the faucet is exposed to certain chemicals, the corrosion process is fastened. Harsh cleaning agents, acidic or alkaline substances, and chemical fumes all contribute to the corrosion of the faucet.

Installation and Maintenance Error

Incorrect installation techniques, improper sealing, or using incompatible materials can lead to accelerated corrosion. Inadequate maintenance, such as neglecting to clean the faucet regularly, can also contribute to corrosion.

Environmental Factor

Environmental conditions are also responsible for faucet corrosion. High humidity level creates a moist environment that builds corrosion.

Extreme temperature variations, such as freezing and thawing cycles, can cause expansion and contraction of the faucet’s metal components, leading to stress and potential corrosion.

How To Identify Corrosion on Faucet?

1. Corroded faucets may exhibit patches of discoloration, such as green, blue, gray, or reddish-brown water stains on the metal surface. These stains are often a result of chemical reactions between the metal and the surrounding environment.
2. Corrosion can make the surface of the faucet appear dull, rough, or pitted. A smooth and shiny finish may become tarnished or lose its smoothness.
3. Corrosion can compromise the durability of the faucet, leading to leaks or drips. If you notice water dripping from the base of the faucet or around the handles, it may indicate corrosion-related damage.
4. Corroded faucets may become stiff or difficult to turn due to the accumulation of rust or damage to internal components. If you experience resistance or unusual stiffness when operating the faucet, corrosion may be the underlying cause.

How To Prevent Faucet Corrosion?

A. Regular Cleaning and Maintenance

Regular cleaning is essential to prevent the build-up of dirt, grime, and mineral deposits that can contribute to faucet corrosion. Follow these techniques and use suitable cleaning products:

1. Use a soft cloth or sponge to wipe the faucet surfaces.
2. For stubborn stains or mineral deposits, create a mixture of equal parts water and vinegar. Apply the solution to the affected areas, let it sit for a few minutes, and then scrub gently with a soft brush or toothbrush. Rinse thoroughly.
3. Avoid using abrasive cleaners or harsh chemicals as they can damage the faucet’s finish and increase the risk of corrosion.
4. For faucets with specific materials or finishes, refer to the manufacturer’s guidelines for cleaning recommendations.

The frequency of cleaning of the faucet depends on several factors, such as water quality, frequency of use, and environmental conditions. As a general guideline, aim to clean your faucets at least once every one to two weeks. However, if you notice any signs of corrosion or mineral build-up, increase the frequency of cleaning as necessary.

B. Improve Water Quality

Poor water quality, including high levels of minerals and chemicals, can accelerate faucet corrosion. Consider the following water quality management measures:

1. Test your water periodically to find mineral quantities in the water. You can use home testing kits or hire professionals to get more accurate results.
2. Based on the test results, consider appropriate water treatment options such as filtration systems, reverse osmosis systems, or water softeners. These devices can help remove impurities, reduce mineral content, and improve water quality, subsequently reducing the risk of corrosion.

If your water contains high levels of minerals, especially calcium, and magnesium, investing in a water softener can be beneficial.

Water softeners remove these minerals, preventing the formation of limescale and reducing the chances of corrosion. Additionally, using a water filter can help remove contaminants and impurities, further improving water quality.

C. Proper Installation and Maintenance Practices

When installing or replacing faucets, opt for high-quality materials that are resistant to corrosion. Look for faucets made of stainless steel, brass, or other corrosion-resistant materials. Avoid faucets with cheap or low-quality finishes, as they are more prone to corrosion.

1. Proper installation is crucial for the long-term durability of faucets. Follow these guidelines:
   • Ensure that all connections are tight and leak-free.
   • Use the plumber’s tape or thread sealant to prevent water leakage around threaded connections.
   • Avoid overtightening, as it can damage the faucet and lead to leaks or cracks.
2. Regularly inspect your faucets for any signs of damage, corrosion, or leaks. Address any issues promptly to prevent further damage.
   • Check for loose connections and tighten them if necessary.
   • Repair any leaks or drips promptly.
   • Replace worn-out or damaged parts, such as O-rings or washers, to prevent leaks and further corrosion.

D. Protective Coatings and Finishes

Protective coatings on the finish act as a barrier between the faucet’s surface and corrosive elements. Common types of coatings include:

1. Chrome plating: This provides a shiny and durable finish, offering protection against corrosion.
2. PVD (Physical Vapor Deposition) coatings: Offer increased durability and resistance to scratching, tarnishing, and corrosion.
3. Powder coating: Provides a durable and chip-resistant finish, suitable for outdoor faucets exposed to harsh environmental conditions

If your faucet doesn’t already have a protective coating or finish, or if the existing coating is wearing off, consider applying a protective layer to prevent corrosion. Here’s how you can do it:

• Clean the faucet thoroughly to remove any dirt, grime, or existing coatings.
• Apply a high-quality metal polish or cleaner to restore the faucet’s shine and remove any surface imperfections.
• Once the faucet is dry, apply a clear protective coating specifically designed for faucets. Follow the manufacturer’s instructions for application, which may involve spraying or brushing the coating onto the faucet surface.
• Allow the protective coating to dry completely before using the faucet.

E. Minimizing Chemical Exposure

Chemicals such as bleach, ammonia, or acidic cleaners can corrode faucets if they come into direct contact. To minimize chemical exposure and reduce the risk of corrosion:

1. Store cleaning products and chemicals away from faucets in a well-ventilated area.
