METHOD OF CLEANING SURFACES IN INTERNAL PREMISES AND IN TECHNICAL EQUIPMENT USING BENIGN BACTERIA Russian patent published in 2020 - IPC B08B15/00 B08B17/02 

FIELD: surface cleaning.

SUBSTANCE: group of inventions relates to cleaning of surfaces in internal premises or in technical equipment. Method of dust deposition reduction in internal premises or on technical equipment, acceleration of cleaning and reduction of cleaning frequency of inner rooms or technical equipment, involves target spraying of an aqueous solution with spores of benign bacteria in concentration between 10⁶ KOE/ml and 50×10⁷ KOE/ml, selected from the genus Bacillus, or from aerobic spore-forming cold-resistant bacteria of the genus Sporosarcina, Paenisporosarcina or Paenibacillus or a combination thereof, on all surfaces by means of electrically and/or pneumatically actuated sprayer, while room remains accessible for people and animals. In an aerosol formed by spraying an aqueous solution, drops acquire the same electric charge due to the ball-electric effect, which is stored on aerosol deposition on dust. Group of inventions also relates to use of said method for cleaning spaces that are difficult to achieve for manual cleaning.

EFFECT: group of inventions provides reduced frequency of cleaning due to reduction of dust deposits.
