In a first-of-its-kind initiative aimed at improving cleanliness across Mumbai's suburban railway network, Western Railway (WR) has launched a pilot project at Matunga Road station using advanced German nano-technology to combat stubborn gutkha and paan masala stains.
The project, implemented at an estimated cost of ₹5 lakh, is designed to make stain removal faster, easier, and more cost-effective. Railway officials believe the innovative coating could significantly improve station maintenance while enhancing the overall passenger experience.
Traditionally, railway cleaning staff spend up to 30 minutes scrubbing paan and gutkha stains from station walls and infrastructure. Even after using acids and specialized cleaning agents, many stains leave behind permanent marks.
With the new nano-coating, officials expect cleaning time to drop dramatically—from around 30 minutes to just five minutes. The protective layer prevents stains, dirt, paint, and graffiti from penetrating surfaces, allowing them to be removed quickly using only water and basic cleaning methods.
The special coating has been applied over approximately 3,700 square feet across eight locations within Matunga Road station. These include walls, pillars, ceilings, elevators, and various metal surfaces.
Marketed under the brand names Wallgard and Metalgard, the coating not only offers anti-stain and anti-graffiti properties but also protects surfaces from rust, weather-related damage, and everyday wear and tear.
According to railway officials, the coating is expected to remain effective for at least five years.
Spitting of gutkha and paan masala remains one of the biggest cleanliness challenges at Mumbai's suburban railway stations. Despite repeated awareness campaigns, penalties, and regular cleaning drives, the issue continues to affect station aesthetics and maintenance costs.
Western Railway officials said the nano-technology solution was introduced after conventional measures failed to produce satisfactory results. The coating creates a durable protective barrier that prevents stains from bonding with the surface, making maintenance considerably easier.
The pilot project's performance will be closely monitored over the coming months. If the results meet expectations, Western Railway plans to extend the technology to other stations across its network.
Officials believe the initiative has the potential to reduce long-term cleaning expenses while keeping public spaces cleaner and more visually appealing. If successful, the experiment could offer a practical and sustainable solution to one of Mumbai's most visible public cleanliness issues.
