The #freeze#jet Dry #ice Blasting System.
Better than #cleaning by water jet or sand .
You can clean even electrical engine .
Maybe expensive but necessary for some cases.
Dry ice blast cleaning uses solid C02 , a non-abrasive media that won't damage surfaces or equipment. The accelerated, super cooled dry ice pellets, are blasted at supersonic speeds and sublimate on impact resulting in the surface being cleaned, lifting dirt and contaminants off the underlying substrate.
