The glowing tubes of neon signs evoke a sense of nostalgia and intrigue that brightly beckons customers inside businesses. But when accumulated dirt and grime diminish their luminous luster over time, the benefits of these fixtures fade as well. Maintaining the radiant glow of neon through basic cleaning preserves the charm and effectiveness of these beloved lighting staples.
From the outside looking in, neon graphics may appear as set-it-and-forget-it permanent fixtures. However, the maintenance of delicate glass tubing and electrical components requires conscientious upkeep. With simple solutions and proper care, commercial custom neon signs sustain visual magnetism to continually attract admiring eyes for years on end. Read below for critical guidelines every neon owner needs to know regarding safety and processes for keeping your prized signage dust-free and shining appetizingly.
1. Handle Fragile Components with Care
Neon lighting contains fragile glass and intricate electrical wiring prone to damage if mishandled. Always exercise extreme caution when cleaning custom neon signs. Turn off the power supply and allow tubes to fully cool before touching to prevent burns or shocks. Use gentle pressure when wiping to avoid scratching or shattering tubes. Take care around thin connecting wires as well. Secure ladders for safe access. While intimidating, neon proves surprisingly sturdy if handled deliberately. However, reckless pressure can fracture the glass or displace wiring connections. Patience prevents harm to valuable lighting.
2. Dust Damp Surfaces for a Sparkling Finish
For surface grime on glass tubing or plastic casing, use microfiber cloths lightly dampened with clean water to lift dust and particulate. Soft cotton towels also suffice. Gently rub dampened cloths along the length of tubing or over casing exteriors to clear cloudiness. The faint moisture helps adhere and embed debris within the cloth, while soft pressure prevents scratching. Finish by buffing dry areas with a fresh lint-free cloth. Strategic dusting maintains clarity for maximum brightness.
3. Spot-Clean Stubborn Grime and Film
For more stubborn grease or smoke residue, use a mild solvent like isopropyl alcohol or diluted vinegar mixed with water. Dip clean soft cloths into the solution before dabbing on bits of stuck-on grime. Avoid aggressively rubbing stains to prevent scratching. Be extra gentle around lettering or decorative paint, as excess friction scrapes away applied colors. If the cleaner cannot lift the mark immediately, let it soak for a few minutes before carefully wiping it again. Repeat light passes of checked cloths until achieving the desired clean state. Harsh chemicals risk damage, so mild solutions with gentle action work best.
4. Check Electrical Connections
When powered off, inspect wiring connections along the neon tube path. Ensure wires remain straight without kinks from stress. Straighten any crooked portions by hand or with pliers if needed, taking care not to tear insulating plastic. Replace cracked wire jacketing with electrical tape. Re-seat any loose plugs or connectors by firmly pressing into ports without bending wires. Solid electrical bonds maintain an even current for consistent lighting. Consult an electrician for complex component replacement if unresolvable DIY. Restore lost connections before restoration burns out.
5. Clear Internal Dust or Buildup
For interior cloudiness within tubing or casing, use an air compressor or strong canned air to forcefully blow out trapped particles. Direct the nozzle perpendicularly across openings rather than blowing debris further back into channels. Cover nearby components to prevent dust blowback before blasting. Confirm electrical pieces remain dry throughout. Repeat blasts until achieving clarity. Compressed air proactively restores unobstructed internal lighting pathways that accumulation gradually blocks over time. Prevent clouding before it cuts brightness.
6. Check Gas Pressure and Refill when Needed
Most neon contains argon/neon gas mixtures that energize phosphor coatings inside the tubing to emit colored light. Brightness fades as gases deplete over years of use. Professionals use vacuum pumps to test pressure. If low, new inert gas injected through valves refreshes vital current flow. Attempting DIY gas refills risks air contamination or over-pressurization. Consult an expert when signs noticeably dim. Proper re-gassing reestablishes colorful luminosity once more. Consider full tube replacement beyond 10-15 years before gas refilling loses effectiveness from additional internal phosphor aging.
7. Repair or Replace Broken Tubing
Cracked or shattered neon tubing requires replacement. Carefully remove the damaged portion using neon pliers. Measure and cut a new tube segment 1-2 inches longer than the missing section for easier mounting. Wipe ends clean with alcohol. Apply silicone or heat-resistant epoxy around one end and smoothly insert into adjoining tubes, aligning the axis. Stake in position for curing before repeating epoxy application to the opposite end. Avoid tube misalignment to prevent hot spots or current leakage. Restore broken vacuum seals for uninterrupted lighting. Replace excessively cracked or patched tubing for optimal safety.
8. Update Old Signs with Modern LED
For neon signs requiring extensive repairs, consider upgrading to modern LED lighting simulated as neon. Cutting out the glass opens reusable sign bodies or casings to insert plastic LED strips or ropes mimicking neon glows. This retrofits custom neon signs efficiently without fragile tubes. However, LEDs never fully replicate the ambient flickering glow of authentic neon filled with vibrant noble gases. Measure aesthetic tradeoffs before abandoning traditional lighting. Blending classic neon portions with LED replacements offers a budget-friendly compromise. Either way, modernizing electrical systems improves energy efficiency and longevity.
9. Hire Professionals for Overhaul Services
Seeking professional neon servicing ensures appropriate handling, materials, and procedures to effectively refresh signs. Experienced companies possess specialized tools and skills the average owner lacks, efficiently restoring brightness. Hire reputable local neon shops rather than general electricians when possible for servicing tailored to the nuanced needs of gas tube lighting. Factor overhaul costs into long-term maintenance budgets. Think preventatively, as spending a little continuously avoids large emergency breakdown fees down the road. Routine professional care sustains neon’s delicate balanced chemistry and moving parts.
10. Inspect Connections and Gases Regularly
Get in the habit of visually checking neon health every few months, more frequently for signs used often or in extreme weather. Monitor tubes and wiring for cracks or looseness before small issues grow severe. Keep an ear tuned to buzzing sounds, listening for any erratic surges, drops, or silence indicating problems. Test buttons that activate flickers or color cycling to catch malfunctions early. Record gas pressure and brightness levels each year as reference points. Logging baseline data helps determine gradual depletion trends for timely refills. Consistent inspection, logging, and preventative repairs enable optimal neon performance year after year.
11. Create Protection Strategies from Weathering
Outdoor neon endures more intense environmental exposure than interior signs. Develop external housing strategies before problems arise. Use overhangs above signs to shield from heavy precipitation. Apply weather-resistant clear coatings to fortify the paint against sun, moisture, and pollution without dulling colors. Clean exterior signs more frequently to prevent deteriorating buildup. Confirm drainage pathways that guide rainwater away from electrical components. In extremely cold climates, enclose signs to maintain ideal thermal conditions for glass properties and electrical conductivity. Defend neon infrastructure proactively since weather-induced damage repairs prove costly.
12. Handle your Neon with Care for Long, Bright Lives
Neon signs contain more intricacies than meet the eye. But when respected through gentle handling, strategic cleaning methods, and preventative maintenance, neon lights beam reliably for decades with that nostalgic charm nothing else replicates. Take measures to avoid moisture interference, inadvertent scratches, loose wiring, gas depletion, and tube fractures threatening otherwise steady operation. With periodic professional servicing and a watchful eye to catch issues early, neon signs remain safe, efficient, and spectacular. After all, quality neon endures when nurtured properly over time.
