Helpful hints on engine cleaning:Engine washing Dust and water splashes build up over time, but do not damage the engine. The time for engine washing is after the winter, when water and road salt have splashed up and left a white deposit.
The best place to clean the engine is at a commercial self-service car wash; this ensures that cleaning chemicals and (for older cars) rinsed-off oil do not get into groundwater. Aggressive products such as acid-containing cold cleaners should not be used to loosen dirt, however, since they can attack electrical equipment and plastics. Water-soluble engine cleaners are more suitable.
