Engine Foam Wash Prevents Damage and Reduces Fuel Burn
Turbofan wash cycle takes between four and eight hours
GE Aerospace foam wash
GE Aerospace developed a process to wash aircraft engines with foam to protect against damage and reduce fuel burn.

Jet engines degrade in normal operating conditions compared with new deliveries. Challenging environments accelerate the degradation of parts and, with this, fuel efficiency.

In the Middle East, for instance, fine dust particles are especially hard on engines. But degradation also occurs in “normal” environments, as well as super-cold ones.
