Neon Signs Maintenance And Care: A Guide To Keeping Your Neon Sign Shining Bright

Neon signs have a timeless allure that can instantly transform the ambiance of any space. Whether it’s the vibrant glow of a classic “Open” sign in a storefront or a custom-designed neon masterpiece illuminating your home, neon signs are a unique form of art and communication. However, like any other lighting fixture, they require proper maintenance and care to ensure they continue to shine brightly and last for years. In our guide to neon sign maintenance and care, we’ll explore valuable tips and techniques that will help keep your Smithers of Stamford neon sign shining bright for years to come.

The Art And Science Of Neon Signs

Before we dive into the maintenance and care aspect, it’s essential to understand a bit about how neon signs work. In order to make neon signs, glass tubes are twisted into complicated forms and filled with noble gases like neon, argon, or krypton. When an electrical current passes through these gases, they emit colorful, vibrant light. The distinctive glow and aesthetic appeal of neon signs come from this unique chemical reaction.

Why Maintenance Matters?

Neon signs are not only decorative but often serve as important visual elements for businesses, events, or personal spaces. Neglecting their maintenance can lead to a loss of functionality, a decrease in brightness, and even premature failure. Proper maintenance ensures that your neon sign not only continues to shine brightly but also operates safely. Here are some reasons why maintenance is crucial:

Prolong Lifespan: Regular maintenance can significantly extend the life of your neon sign. Proper care can prevent issues that might lead to expensive repairs or the need for a complete replacement.

Ensures Safety: Neon signs involve electrical components and gases, making safety a top priority. Regular maintenance helps identify and rectify potential safety hazards promptly.

Maintains Aesthetic Appeal: The allure of neon signs lies in their vibrant colors and captivating glow. Routine care ensures that your sign retains its visual impact.

Cost-Efficiency: It’s often more cost-effective to invest in regular maintenance than to deal with extensive repairs or replacements due to neglect.

Now, let’s explore the steps you can take to maintain and care for your neon sign.

Cleaning Your Neon Sign

Cleaning is one of the most straightforward yet essential aspects of neon sign maintenance. Over time, grit, filth, and grime can accumulate on the glass, diminishing the brightness and vibrancy of the sign. Here’s how to clean your neon sign effectively:

Materials Needed:

  • Soft, lint-free microfiber cloth
  • Mild glass cleaner
  • Soft-bristle brush or compressed air (for hard-to-reach areas)
  • Latex or nitrile gloves (optional)


Safety First: Ensure that your neon sign is turned off and disconnected from the electrical source before beginning. Safety should always be a priority when handling electrical components.

Dust Removal: Gently remove dust from the sign’s surface using a soft, dry microfiber cloth. Be careful not to scratch the glass.

Cleaning: Spray a small amount of mild glass cleaner onto another clean microfiber cloth. Avoid spraying directly onto the sign, as excess liquid can seep into the glass tubes and damage the electrical components.

Wipe Down: Gently wipe the sign’s glass tubes and any exposed metal parts using the cloth dampened with glass cleaner. Be comprehensive but careful to avoid breaking the fragile glass.

Detail Cleaning: For hard-to-reach areas or intricate designs, use a soft-bristle brush or compressed air to dislodge any remaining dust or dirt particles.

Dry Thoroughly: Allow the sign to air dry thoroughly before re-powering or connecting it in.

Checking For Damage And Wear

Regularly inspecting your neon sign for damage is crucial in preventing small issues from becoming more significant problems. Here’s what to look for during your visual inspection:

Cracks Or Breaks: Examine the glass tubes carefully for any visible cracks or breaks. Even tiny fractures can compromise the structural integrity of the sign.

Flickering Or Dimming: Turn on the neon sign and observe its brightness. If you notice flickering or dimming, it may indicate issues with the electrical components, such as loose wiring or failing transformers.

Color Consistency: Ensure that the colors produced by the neon sign are consistent with its original design. Discoloration or uneven lighting can be signs of aging or damage.

Leaks: Check for any signs of gas leaks, such as a hissing sound or a noticeable drop in brightness. Gas leaks can pose safety hazards and should be addressed promptly by a professional.

Storing And Transporting Neon Signs

If you need to store or transport your neon sign, follow these guidelines to ensure its safety and protection:

Disconnect And Pack Carefully: Before moving or storing your neon sign, disconnect it from the power source and allow it to cool down if it has been in use. Wrap the sign in soft, clean blankets or bubble wrap to protect the glass tubes from damage during transit.

Avoid Extreme Temperatures: Store your neon sign in a climate-controlled environment, away from extreme heat or cold. Temperature fluctuations can cause glass tubes to expand or contract, potentially leading to breakage.

Secure Transportation: When transporting a neon sign, ensure it is securely fastened to prevent movement or impact damage. Use a vehicle with a smooth ride, and avoid rough or bumpy roads.

Consult A Professional: If you’re unsure about how to properly store or transport your neon sign, consult with a professional neon sign specialist for guidance.


Neon signs are not just sources of light; they are works of art that enhance the atmosphere of any space. To maintain their beauty, functionality, and safety, it’s crucial to invest time in their maintenance and care. Regular cleaning, visual inspections, and prompt professional assistance for any issues are key to keeping your neon sign shining bright for years to come. With proper care, your neon sign will continue to captivate and illuminate, adding a touch of vibrant nostalgia to your environment.
