Equipment maintenance service providers have begun promoting an integrated "clean-lubricate-protect" solution. For example, some companies have launched products that sequentially release cleaner and lubricant from the same spray can. The first step, a powerful cleaner, removes old grease, sludge, and contaminants, while the second step, a lubricant, provides instant protection for the parts. This innovation is particularly suitable for online maintenance of open components such as conveyors and chains, helping to reduce downtime and improve maintenance efficiency.
