The short answer
Clean acrylic and metal faces gently with a soft cloth and mild soap, never solvents or abrasive pads. Keep drain holes clear after the monsoon, keep power supplies ventilated and accessible, and check fixings and wiring periodically. Replace failed LED modules early so the sign stays evenly lit.
Why maintenance matters
A sign is often the first part of a business that customers see. Dust, a dark letter or a stained fascia sends the wrong message. Most problems can be avoided with simple, regular care.
Cleaning by material
| Surface | Clean with | Avoid |
|---|---|---|
| Acrylic faces | Soft cloth, mild soap and water | Thinners, alcohol, ammonia, dry wiping of dusty faces |
| Stainless steel | Mild soap and water, then dry | Bleach, chloride cleaners, steel wool |
| PVD finishes | Soft cloth, mild soap | Abrasive pads and powders |
| Brass | Soft cloth; brass care products if unlacquered | Abrasives on lacquered brass |
| ACP panels | Water and mild detergent | High-pressure jets at joints |
Always switch off and isolate illuminated signs before cleaning, and use safe access equipment for signs at height.
Seasonal checks for Delhi NCR
- Before the monsoon: check sealant, drain holes and electrical connections on outdoor signs.
- After the monsoon: look for water marks inside letters or lightboxes, and for rust on exposed steel frames.
- Summer: keep power supplies ventilated. Heat shortens the life of electronic parts.
- Winter and dust season: clean faces more often, as pollution film dulls the light.
When to call for service
- One or more letters are dim, dark or flickering
- Water is visible inside a letter or lightbox
- A bracket, panel or letter has moved
- The sign trips the electrical circuit
LED modules and power supplies can usually be replaced individually, so a small fault does not mean a new sign. Contact us with photos and we will advise.
