FIELD: process engineering.
SUBSTANCE: invention relates to abrasive-jet cleaning of surfaces from organic dirt and may be used in cleaning industrial equipment. Abrasive is forced onto processed surface in compressed air jet with addition of water and surfactant thereto. Abrasive represents the following composition, in wt %: soft abrasive 60-80, solid abrasive 10-30, sodium carbonate 10. Abrasive is fed onto processed surface at 8 atm. Water forced into flow contains 0.1-2 wt % of surfactant in amount of 10-150% of total weight of composition.
EFFECT: higher cleaning efficiency, ease of waste disposal.
