Estimating the term…
A high-pressure cleaning device, a cleaning dispersion, and a combination of a high-pressure cleaning device with a surface to be cleaned. The cleaning device cleans surfaces soiled by fine particles, particularly motor vehicle surfaces, and includes a high-pressure pump for delivering a cleaning product to a high-pressure jet nozzle. The cleaning product emerges in a high-pressure jet. The cleaning product includes a cleaning dispersion with a carrier fluid and solid cleaning particles having a density of between 0.8 g/cm3 and 3.5 g/cm3. Cleaning particles emerge from the high-pressure jet nozzle having a minimum kinetic energy of 1·10−10 J and a maximum kinetic energy of 2·10−4 J.
A high-pressure cleaning device for material-friendly cleaning of surfaces contaminated with fine particles, in particular motor-vehicle surfaces, comprising a high-pressure pump for conveying a cleaning product to a high-pressure jet nozzle at which the cleaning product exits in a high-pressure jet, wherein the cleaning product comprises a cleaning dispersion with a carrier fluid and with solid cleaning particles with a density of between 0.8 g/cm3 and 3.5 g/cm3, preferably between 0.9 g/cm3 and 2.2 g/cm3, and the high-pressure cleaning device is configured in such a way that a cleaning particle, upon exiting the high-pressure jet nozzle, has a kinetic energy of a minimum of 1·10−10 J and a maximum of 2·10−4 J.
A high-pressure cleaning device in combination with a surface to be cleaned, the high-pressure cleaning device configured for material-friendly cleaning with a high-pressure pump for conveying a cleaning product to a high-pressure jet nozzle, at which the cleaning product exits in a high-pressure jet, wherein the cleaning product comprises a cleaning dispersion with a carrier fluid and with solid cleaning particles with a density between 0.8 g/cm3 and 3.5 g/cm3, and the high-pressure cleaning device is configured in such a way that a cleaning particle, when hitting the surface, has a kinetic energy of a minimum of 1·10−10 J and a maximum of 2·10−4 J.
