Handling AdBlue contaminated by foreign substances
Individual components of the BlueTec SCR system react very sensitively to even the
smallest traces of impurities in AdBlue. Therefore, when handling AdBlue, it is always
necessary to use only clean containers and collecting tanks dedicated to this purpose.
AdBlue that contain traces of impurities may not be used further.
Usage period and storage life
During storage, AdBlue decomposes into ammonium hydroxide and carbon dioxide
and thereby no longer meets the requirements of the DIN 70070 standard. If the rec-
ommended storage temperature of maximum 25°C is maintained, then AdBlue meets
the requirements of this norm for at least 6 months after its date of manufacture. If
the recommended storage temperature is exceeded, then this period is shortened.
AdBlue freezes and solidifies at temperatures below -11°C. If warmed, frozen AdBlue
will again liquefy and can be used again without degradation of quality. Refer to the
Mercedes-Benz Specifications for Operating Fluids (MB BeVo) for information regard-
ing the maximum permitted usage period of AdBlue.
Disposal and degradability
AdBlue only poses a low level of danger to water bodies and soil. It can be further
used by microbes and is therefore easily decomposed. For this reason, AdBlue is
classified in Germany in the lowest risk category of WGK 1 water hazards (German
Water Hazard Classification).

tive national laws.
