Before cleaning a neon sign, make sure it is completely turned off and unplugged. This minimizes the risk of electrical shock or damage.

Also, ensure you are in a well-lit area to spot any dirt or grime that needs removing.

Using a soft, dry microfiber cloth or a feather duster, gently remove any loose dust or debris from the surface of the neon sign. Take care not to apply pressure or scratch the delicate glass tubes.

If the sign has hard-to-reach areas, you can use a soft-bristle brush or a can of compressed air to dislodge the dirt.

Create a mild cleaning solution by mixing a few drops of dish soap or glass cleaner with warm water.

Avoid using harsh chemicals, abrasive cleaners, or ammonia-based products as they can cause discoloration or damage to the neon tubes.

Dip a soft cloth or sponge into the prepared cleaning solution and gently wipe the surface of the neon sign. Use gentle circular motions to remove any stubborn dirt or stains.

Take extra care around the delicate glass tubes not to apply excessive pressure or force.

Rinse the cloth or sponge regularly in clean water to prevent smearing the dirt back onto the sign.

After cleaning, use a clean and dry microfiber cloth to carefully remove any excess moisture from the neon sign.

Allow the sign to air dry completely before turning it back on or plugging it in to avoid potential damage.

To maintain the brightness of your neon sign, it’s recommended to clean it at least once every three months, or more frequently if you notice it becoming dull.

Regularly inspect the sign for any loose connections, broken tubes, or signs of damage. If you find any issues, it’s best to consult a professional neon sign repair technician.
