Neon signs, as a decorative feature, have entered our lives in so many ways that, regardless of their purpose, whether they entice someone to a business, decorate a home, or provide atmosphere at an event, neon signs are a good item. 

Similar to any other decorations, they are likely to accumulate dirt and dust. While the accumulation of dust and dirt may lessen or dull your neon signage, cleaning your neon decorations will allow you to get the most life out of them. How, then, should a neon sign be cleaned?

I. What tools and materials are needed to clean neon signs?

Neon Sign Materials

Before you actually clean, it's necessary to obtain some of the tools you will need.

 1.  A microfiber cloth, soft (the perfect material choice for cleaning glass surfaces without leaving a residue).

 2.  A small or soft-bristle brush—a great instrument for removing stains in inaccessible areas and delicate areas around the lamps.A mild detergent—a mild cleaning solution to remove tough, nasty dirt without damaging the neon sign.

 3.  Gloves—protect your hands from leaving fingerprints and oils that may transfer to the neon sign.

II. How to clean neon signs?

1. Unplug the power cord

Before cleaning, make sure to unplug the neon sign from its electrical source. This provides you with safety and the electrical parts.

2. Remove dust

To remove loose dust, use a soft-bristled brush or a microfiber cloth and gently wipe dust off the tubes and frame. Be careful around sensitive areas that could break.

3. Gently wipe the sign

Next, use a diluted mild detergent and water solution and wet the microfiber cloth. Wipe down the tubes carefully, not to introduce moisture in the electrical parts. You may also want to use a small brush or a room and swab to clean tighter areas.

4. Plug in and inspect

Let the sign dry completely before plugging it in and inspecting it for functionality. After plugging it back in, verify that it appears to glow evenly and is operating correctly.

III. Neon sign maintenance tips

Neon Signs

1. Use anti-rust oil on screws.

Make sure you have anti-rust oil applied to any screws. The metal parts are designed to resist rust and corrosion caused by moisture and outdoor elements.

2. Do not stack up neon signs.

Do not stack neon signs when they are in their shipping containers. It not only puts added pressure on the neon signs that could cause them to crack or break, but it is also dangerous.

3. Dust your neon signs regularly.

Lightly dust your neon signs every couple of weeks to help keep them bright. Dust will decrease the amount of illumination the neon will produce as it builds up.

4. Do not move the installed neon.

Once the neon tubes are installed, do not bend or move them so as to prevent them from breaking. Remember that premier neon signs are exceptionally fragile. When moving them, do so extremely cautiously.

IV. Conclusion

Just remember to always use the correct cleaning and care materials, the correct way to use the materials, including safety precautions, such as unplugging the sign before you clean it. 

While maintenance may take some effort, it makes a difference from a cosmetic point of view. Regular maintenance does a lot more than keep neon signs glowing. It allows them to merely function. As a decorative object or as an aesthetic branding tool with ambiance, neon signs will last longer when maintained properly.
