Two spray-applied cleaning chemicals for removing contami nants from engine or gearbox components have been introduced by Diversey.
Diverspray 50 is a heavyduty cleaner for steel and ferous alloys. It is a viscous alkaline chemical normally used with water in a 0.25 to 1.5 per cent solution.
Components are sprayed from one to three minutes at temperatures between 40deg C and 80deg C.
Diverspray 62 is a clear, slightly viscous chemical, less alkaline than the 50 but used in similar concentrations. Cleaning time is one to two minutes at temperatures from ambient to 80deg C.
Both products incorporate water softening agents to prevent scale build-up in spray nozzles, stand pipes and heating coils.
