A hard surface cleaning composition, methods of cleaning a hard surface with a low hysteresis composition and disposable premoistened pads for cleaning hard surfaces are provided. The hard surface cleaning composition includes from 0.01 wt. % to 7 wt. % of a solvent selected from the group consisting of a propylene glycol phenyl ether, a dipropylene glycol phenyl ethers and mixtures thereof and at least 92% water. The cleaning composition has a pH from about 3.5 to 9.5 and is free of anionic surfactant and alkanolamine.

Methods for forming multi-layer substrates including top and bottom surface layers and a melt softened thermoplastic material layer between the exterior surface layers, where the thermoplastic material includes polyethylene or has a tan delta value of 0.2 to 0.4 within the temperature range of 100 F.-350 F. The 3 (or more) layers are assembled, and heated, melt softening the thermoplastic material, causing bonding of the thermoplastic layer to the exterior surface layers. A cleaning composition may be loaded onto the multi-layer substrate, where a fluid pathway through the melted thermoplastic material allows the cleaning composition to travel between the surface layers. Adhesion between the surface layers and the thermoplastic layer is provided by the thermoplastic material itself, which bonds to groups of fibers in the surface layers. The process does not require chemical adhesives, any processing water, drying, or the like, so as to be possible with low capital investment.

A cleaning device includes: a lens cover configured to cover an object lens of a camera provided in a machining area of a machine tool, the lens cover being transparent; a motor configured to rotate the lens cover; and a wiping member configured to, when the lens cover rotates, wipe at least an adhering substance that has adhered to a region of the lens cover in an angle-of-view of the camera.

A wet wiper for cleaning accumulated oral debris from removable dental appliances. The wet wiper comprises (a) a water insoluble substrate; and (b) a physiologically acceptable cleansing composition, said cleansing composition comprising: a solution of water and a flavorant, wherein said water is up to about 97% by weight of said cleansing composition; and said flavorant is about 0.001% to about 5% by weight of said cleansing composition. Methods for cleaning removable dental appliances are also provided, such methods comprising the step of contacting, for a time sufficient to reduce oral debris, the removable dental appliances, with a wet wiper of the present invention.

In an example, a wiper system includes a first wiper blade, a second wiper blade, and a liquid dispenser. In that example, the liquid dispenser is oriented to eject liquid towards a cloth area across from the first wiper blade when the first wiper blade is in a rest position and the second wiper blade is in a service position.

A spunbond nonwoven fabric. The fabric has a first surface and a second surface and at least a first and second visually discernible zone on at least one of the first and second surface, each of the first and second zones having a pattern of three-dimensional features, each of the three-dimensional features defining a microzone. Each microzone has a first region and a second region, the first and second regions having a difference in values for an intensive property, and wherein the difference in values for an intensive property for at least one of the microzones in the first zone is different from the difference in values for the intensive property for at least one of the microzones in the second zone.

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 device cleans a surface of a sheet conveyance member which conveys a sheet in an image forming apparatus that executes image forming processing using a recording material, the surface carrying a solid substance that originates from the recording material and that adheres to the surface. The cleaning device includes a cleaning member including a contact surface configured to come in contact with the surface of the sheet conveyance member. The contact surface is an irregular surface rougher than the surface of the sheet conveyance member. At cleaning of the surface, the cleaning member makes a relative movement to the surface of the sheet conveyance member. The irregular surface is an irregular surface configured to take away the solid substance adhering to the surface of the sheet conveyance member when the cleaning member makes the relative movement.

A wipe article includes a substrate, a cationic coating disposed on a surface of the substrate, distributed throughout the substrate, or both. The cationic coating contains a guanidinyl-containing polymer that is crosslinked and bound to the substrate. The substrate includes sponge, nonwoven fabric, or woven fabric. The wipes are useful for removing microorganisms from a microorganism-contaminated surface and also for reducing re-contamination of the cleaned surface or transfer to another surface of the removed microorganisms.

A pre-loaded cleaning substrate, and related systems and methods for picking up particles with an aspect ratio (L/D) greater than 300 (e.g., hair), or greater than 1200 (e.g., particularly long hairs). The substrate (e.g., a nonwoven) may include only a single layer of material. The pre-loaded substrate is loaded (e.g., during manufacture) with a cleaning composition. The fibers of the substrate may have an average diameter less than 15 m, the substrate may have an air permeability of 35 ft.sup.3/min to 75 ft.sup.3/min, and the liquid cleaning composition may have a surface tension of less than about 50 dynes/cm. Together, the combination of the particular substrate and cleaning composition may facilitate markedly improved ability to pick up high L/D aspect ratio particle debris (e.g., such as hair), while retaining such particles (e.g., providing hair retention index values of at least 20).
