Road signs play a crucial role in ensuring road safety and efficient navigation. To maintain their effectiveness and extend their lifespan, regular maintenance and proper cleaning are essential. At B.M.R. Mfg. Inc., we understand the importance of keeping road signs in top condition. In this blog post, we'll share practical tips for maintaining and cleaning road signs to ensure they last longer and remain effective.


1. Regular Inspections and Maintenance

Regular inspections are the first step in maintaining road signs. Conducting inspections at least twice a year, and after severe weather events, helps identify any damage, fading, or vandalism. Using a checklist during inspections ensures all aspects of the sign are evaluated, including visibility, mounting stability, and reflectivity. When damage is found, it’s important to repair or replace the signs promptly to maintain road safety and prevent further deterioration. Common issues to look for include bent or broken signposts, peeling reflective sheeting, and faded or illegible text. Maintaining the signposts and mounting hardware is equally important. Ensuring that these components are secure and in good condition involves tightening loose bolts and replacing corroded or damaged hardware as needed. Regular checks for rust or corrosion on metal parts, and applying rust-inhibiting treatments, can significantly extend the life of a sign.


2. Cleaning

Cleaning road signs properly is vital for maintaining their visibility and effectiveness. Using mild soap and water or a non-abrasive, eco-friendly cleaner is recommended over harsh chemicals that can damage the sign’s reflective sheeting or paint. For stubborn stains or graffiti, specialized cleaning solutions designed for road signs should be used, following the manufacturer’s instructions. Gentle cleaning techniques, such as using a soft cloth or sponge, help avoid scratching the sign. After cleaning, rinsing thoroughly with clean water removes any soap residue, which can attract dirt and reduce reflectivity. Graffiti should be removed promptly to maintain the sign’s visibility and prevent further vandalism. Using a graffiti remover that is safe for use on reflective sheeting is crucial, and you may want to test the remover on a small area first to ensure no adverse reactions occur. Additionally, it is important not to apply any coatings or films over the reflective surface, as this can reduce its effectiveness.


3. Seasonal Maintenance

Seasonal maintenance is also key to extending the life of road signs. In winter, removing snow and ice buildup with a soft brush or broom prevents scratches and maintains visibility. Signs should also be inspected for damage caused by snowplows or road salt, which can accelerate corrosion. In summer, frequent cleanings may be necessary due to the accumulation of dust. Checking for sun damage or fading is particularly important in areas with intense sunlight, and signs should be replaced if their reflectivity or legibility is compromised.


4. Record Keeping and Monitoring

Keeping detailed records of all inspections, cleanings, and maintenance activities helps track the condition of each sign and schedule timely interventions. Recording observations of wear and tear and planning for replacements as signs approach the end of their effective lifespan ensures continued safety and effectiveness. Utilizing digital monitoring systems to track the status and maintenance history of road signs can improve efficiency and ensure no sign is overlooked. GPS mapping to document the location of each sign facilitates easy identification and management.



Maintaining and cleaning road signs is essential for ensuring their longevity and effectiveness. By conducting regular inspections, using appropriate cleaning methods, and addressing damage promptly, you can keep your road signs in top condition. At B.M.R. Mfg.
