The Problem
Only a few months after installation extensive corrosion in the form of external rust started showing on stainless steel fittings (benches, handrails, waste bins, drain pipes) in the area of a railway station. This was mainly caused by deposits of ferrite particles that occur due to the abrasion in the braking process of the railway.
The task
actual removal of the corrosion
application of effective cleaning products
Cleaning technology
Surface cleaner FR-D was applied to the surfaces with a sponge. After an exposure time of 10 – 30 minutes the surface was rinsed with water (using handspray pressure pump P-DZ). The weather conditions at the time: dry, partly cloudy, 12 °C. To apply the surface cleaner it took 2 minutes per m² and per 5 running metres of handrail.
Effectiveness and requirements
The application of FR-D brought about an excellent result, the corrosion was removed completely. The application time varied depending on the surface structure with a maximum of 10 minutes for smooth, polished surfaces and up to 30 minutes on bead-blasted surfaces. Material usage: 0,5 kg per 10 m² or 100 running metres
Additionally we tested the cleaner R 500. It succeeded in removing graffiti without difficulties..
