METHOD OF CLEANING Russian patent published in 2014 - IPC D06F17/00 C11D3/00 

FIELD: process engineering.

SUBSTANCE: proposed method comprises placing the part into container that sustains a variable pressure. Foam composition is applied to the part including at least one foaming agent, at least one ferment and dissolved gas. Note here that said foam composition is redistributed over the part at application and/or after part cleaning. The part is cleaned by foam composition at application of variable pressure to container. Besides, said part is rinsed with appropriate fluid at pressure application to said container. Note here that pressure in said container is increased unless said foam composition behaves as a fluid.

EFFECT: better cleaning.
