Manholes divert rain water straight into the nearest watercourse, lake or sea. Pollution from car washing in the street will thus not be filtered out in a treatment plant.” (Driving Licence Book, 19th Edition, page 223)

In that case, it is slightly better to wash it on a gravel surface since the pollutants are then deposited on the ground in a thinner layer. On a gravel surface, there are also no plants to be damaged.
