A method for cleaning a substrate includes the following: exposing the substrate to a cleaning agent to remove impurities on a surface of the substrate; exposing the substrate to a dewetting chemical agent in a liquid phase to remove the cleaning agent on the surface of the substrate; solidifying the dewetting chemical agent in the liquid phase remaining on the surface of the substrate to obtain the dewetting chemical agent in a solid phase; and sublimating and removing the dewetting chemical agent in the solid phase.

A vehicle-cleaning system and method of cleaning a vehicle are provided, the system comprises a cleaning agent dispenser configured to administer a cleaning agent to a surface of a vehicle for cleaning, wherein the cleaning agent preferably comprises one or more nanoparticulate metal oxide. In one embodiment, the system comprises a chemical agent dispenser configured to separately administer a chemical agent to the surface of a vehicle to react with said cleaning agent to form a resultant foam. The system further comprises an electromagnetic wave emitting system for providing wavelength in a range of about 200 nm to about 380 nm to activate the nanoparticulate metal oxide.

The present disclosure relates to compositions and methods of using the compositions for treating a floor surface. The disclosed compositions clean the floor surface, repair damage, or maintain the original look of the floor. The disclosed compositions also do not provide a permanent finish on the floor, are temporary coatings, or do not significantly change the gloss of the floor after application.

A bio resin agent cleaner and protectant for painted automotive surface finishes, clear coat finishes, fiberglass, chrome, rubber, plastic, gel coat, aluminum, steel, and glass surfaces. In addition to cleaning and protecting the product leaves a semi permanent gloss on most all surfaces. The bio resin agent cleaner and protectant may be a soy bio resin, a grapeseed bio resin, a sunflower bio resin, a vegetable based bio resin, or any equivalent bio resin, for example a soy methyl ester based from soy oil. In one embodiment the bio resin agent cleaner and protectant is a bio resin combined with surfactants and emulsifiers. The bio resin agent addresses the needs for cleaning and protecting painted automotive surfaces.

The present disclosure provides an antimicrobial composition that includes: an antimicrobial component having at least one quaternary ammonium compound; a synthetic polymer that includes: at least one cationic monomer A.sub.b, optionally, at least one anionic monomer B.sub.a, and optionally, at least one non-ionic monomer C.sub.a; an organic acid; and a surfactant selected from cationic surfactants, amphoteric surfactants and combinations thereof; and at least one non-ionic surfactant selected from the group consisting of low hydrophilic-lipophilic balance (HLB) non-ionic surfactants with a delocalized electronic structure that have moderate to poor water solubility. This composition when applied to a surface demonstrates good cleaning ability and provides robust long lasting disinfection.

One aspect of the invention is a new foam which includes a liquid having a plurality of bubbles therein and a plurality of particles suspended therein. The foam is made in a dispenser that suspends the bubbles in the liquid. The liquid may be a single liquid with particles therein or may be made from two liquids which are mixed together. The particles may be such that, prior to foaming the particles sink, float or are suspended in the liquid.

Foaming fibrous structures containing one or more particles, foaming fibrous structure products made therefrom, and methods for making same are provided.

There are provided a solvent composition containing tDCE, which does not exert an adverse effect on the global environment, has high solubility and incombustibility, and can maintain initial incombustibility even in use accompanied by a phase change, a cleaning method using the solvent composition, a coating film-forming composition including the solvent composition, and a method of forming a homogeneous coating film using the coating film-forming composition. A solvent composition includes: tDCE; a first HFE having a boiling point of 40 to 65 C.; and a second HFE having a boiling point of 70 to 120 C., in which a ratio of tDCE is 65 to 80 mass %, a ratio of the first HFE is 5 to 25 mass %, and a ratio of the second HFE is 5 to 25 mass % with respect to a total amount of tDCE, the first HFE, and the second HFE.

A simplified method for removing foreign matters formed on a substrate in a semiconductor device manufacturing process; and a composition for forming a coating film for foreign matter removal use, which can be used in the method. A coating film is formed on a semiconductor substrate using a composition preferably containing a polyamic acid produced from (a) a tetracarboxylic dianhydride compound and (b) a diamine compound having at least one carboxyl group or a polyamic acid produced from (a) a tetracarboxylic dianhydride compound, (b) a diamine compound having at least one carboxyl group and (c) a diamine compound, and then foreign matters occurring on the coating film are removed together with the coating film by the treatment with a developing solution.

A substrate treating method, liquid and apparatus are provided which can reduce the amount of sublimable substance used for the drying of a substrate while reducing the collapse of pattern. The substrate treating method includes a step of supplying a liquid to the pattern-formed surface of the substrate, a step of solidifying the liquid on the pattern-formed surface to form a solidified body and a step of subliming the solidified body so as to remove it from the pattern-formed surface. The substrate treating liquid includes a molten sublimable substance and a solvent, the freezing point of the sublimable substance being higher than the freezing point of the solvent. When the sublimable substance and the solvent are separated, the sublimable substance is settled and in the solidification step, the settled sublimable substance is solidified to have a height equal to or higher than the height of a pattern.
