If you want your neon sign to remain in top condition and continue to impress your friends and family for years to come, it's important to keep it clean. To do so, follow these simple steps: a) Use a cotton cloth with ethyl alcohol to maintain its fresh and clean appearance. b) Use a microfibre cloth or duster to remove any excess dust that may accumulate on your neon sign. c) Avoid using too much fluid when cleaning, as this can cause the fluid to seep under the tubing and cause the LED's to malfunction. By following these easy steps, you can keep your neon sign looking great and functioning properly for a long time!
