* When using the lockers in public areas, in which the increased use of road salt is to be expected during the winter months, we recommend using the electrolytically zinc-plated sheet steel and shoe trays.
The classifications apply to all corrosion protection classes only when the surface is undamaged.
The following test methods are used regularly at the CP testing laboratory
DIN 50021: Salt spray test with subsequent testing according to DIN 53167

Recommended cleaning agents for coated surfaces
Listed below are several recommendations from our suppliers for coating material:
- If possible, please use clean water, possibly adding low amounts of neutral or very slightly alkaline cleaning agents. A mechanical cleaning effect can be achieved with the aid of soft, non-abrasive cloths or rags.
- Do not use any steam jet cleaners.
- Do not use any scratching or grinding agents (abrasive cleaning).
- Do not use any organic solvents containing esters, ketones, alcohols, aromatic compounds, glycol ethers, halogenated hydrocarbons or similar.
- Do not use any cleaning agents of unknown composition.
- Important: Rinse off all cleaning agents with clean, cold water immediately.
