Abstract
A method to clean an article or an object wherein the surface of the article or object to be cleaned (i) is in contact with one or more liquids having a dielectric constant of from 1 to 200, and is (ii) placed in an electric field in the range of 103 V/m to a value limited by the stability of the liquid in the field generated using an alternating voltage/current source.
Claims10
A method of cleaning an article or an object wherein the surface of the article or object to be cleaned is
- (i) in contact with one or more organic solvents having a dielectric constant of from 1 to 200;
- and
- (ii) placed in an electric field in the range of 103 V/m to a value limited by the stability of the one or more organic solvents in the field generated using an alternating voltage/current source.
A method of cleaning an article or an object wherein the surface of the article or object to be cleaned is
- (i) in contact with an aqueous surfactant solution having a dielectric constant of from 1 to 200 wherein the total concentration of the surfactants in water is such that the aqueous solution has a surface tension of less than 50 mN;
- and
- (ii) placed in an electric field in the range of 103 V/m to a value limited by the stability of the aqueous surfactant solution in the field generated using an alternating voltage/current source.
