An apparatus which can remove particles, such as polishing debris, from a back surface with high removal efficiency is provided. The apparatus includes: a substrate holder configured to rotate the substrate while holding the substrate with the back surface facing upward; a scrub cleaning tool configured to be rotatable; a two-fluid nozzle disposed above the substrate holder; and a housing defining a cleaning chamber in which the substrate holder, the scrub cleaning tool, and the two-fluid nozzle are located.

Systems and methods for preventing cross contamination including a grasping handle for use with a container. In example embodiments, the grasping handle can be integrally formed or removably mounted with the container or a cap that is removably connectable with the container. In one example embodiment, a dispensing cap having a grasping handle extending therefrom can be provided for attachment to a desired container. A packaged sanitary wipe can be provided for cleaning the grasping handle and a foil package thereof can cover at least a portion of the grasping handle to provide a sanitary barrier therebetween. Methods of preventing cross contamination when using condiments contained within containers are also disclosed.

The present application provides a cleaning apparatus and a cleaning method. The cleaning apparatus includes two wiping parts opposite to each other, a connection part and a cleanliness detection device. The two wiping parts defines a space therebetween to accommodate a part to be cleaned. The two wiping parts are connected through the connection part. The cleanliness detection device is configured to detect cleanliness of the part to be cleaned. The connection part is configured to control a distance between the two wiping parts based on the detected cleanliness.

A cleaning assembly for cleaning a surface includes a plurality of first panels. The first panels are stacked on top of each other. Each of the first panels is comprised of a deformable material thereby facilitating each of the first panels clean a surface. A coupler is provided that selectively engages a finger. The coupler is coupled to each of the first panels thereby facilitating the plurality of first panels to be manipulated to clean the surface.

A cleaning tool for cleaning an optical connector including a plurality of ferrules, including: a plurality of heads whose pressing surfaces are spanned by a cleaner, each of the pressing surfaces being for pressing the cleaner against the ferrules; a guide member that is placed sandwiched between the heads, and that guides the heads in such a manner that the heads can move rearward; and a cover that accommodates the plurality of heads and the guide member and that exposes the cleaner.

A method for cleaning an interior of a motor vehicle, in particular an autonomously drivable motor vehicle, which includes the following steps recording at least one floor area of the interior by means of at least one camera device, determining a level of soiling of the floor area by evaluating the image recorded by the camera device, and cleaning at least the floor area, when the determined level of soiling exceeds a predefinable first limiting value.

A display module terminal cleansing device includes a wiper assembly and a gas blower assembly. The gas blower assembly is first operated to blow away particle foreign substances located on a terminal area to be cleansed And, then, the wiper assembly is operated to wipe off foreign substances remaining on the terminal area. The display module terminal cleansing device may achieve an effect of cleansing where water droplet angle on the surface of the cleansed terminal area is less than 15 and also prevents a potential issue of scratching and damaging the display module during the process of cleansing. Also disclosed is a display module terminal cleansing method.

A lens and/or a view screen of an electronic device having at least one case can be cleaned by wiping the view screen with a cleaning component wherein the cleaning component is configured to selectively couple to the at least one case or some other substrate using a magnetic attractive force. The cleaning devices may have secondary applications such as securing fly fishing lures, activating or deactivating a device having a magnetic switch, or preventing sunglasses from sinking. They may also be manufactured without a cleaning component for use with the secondary applications.

The present invention relates to aqueous compositions of associative polyelectrolyte complexes (PECs), optionally containing surfactants, biocidal agents and/or oxidants, which can provide a cleaning benefit and surface protection to treated articles including reduced soiling tendency, reduced cleaning effort and improved soil repellancy, as well as providing bacteriostatic properties to treated surfaces that thereby gain resistance to water, environmental exposure and microbial challenge. Treatment means and compositions are provided that employ associative polyelectrolyte complexes formed by combining a water soluble cationic first polyelectrolyte with a water soluble second polyelectrolyte bearing groups of opposite charge to the first polyelectrolyte under suitable mixing conditions and at least one oxidant selected from the group: alkaline metal salts and/or alkaline earth metal salts of hypochlorous acid, hypochlorous acid, solubilized chlorine, any source of free chlorine, acidic sodium chlorite, active chlorine generating compound and any combinations or mixtures thereof. Also provided are means to form stable associative polyelectrolyte complexes with at least one oxidant in aqueous solutions having R values from about 0.10 to 20.
