A method of selectively removing a contaminant from an optical component formed from lithium tantalate includes washing the optical component with a washing solution that includes a hard anion. The contaminant includes a hard cation. The method also includes forming a compound including the hard anion and the hard cation and rinsing the compound from the lithium tantalate to thereby selectively remove the contaminant from the optical component.

Provided is a cleaning agent composition for use in an adhesion process for applying an adhesive to a surface of a first member subjected to a dry treatment without a primer, and adhering a second member to the surface of the first member. The cleaning agent comprises a compound (A) having a (meth)acryloyl group and a liquid (B) having a boiling point of not higher than 200 C.

A window panel recycling equipment may include a first cleaning pad assembly, a first driving member rotating the first cleaning pad assembly, and a cleaning solution supplying member supplying a cleaning solution to the first cleaning pad assembly. The first cleaning pad assembly may include a first rotating member coupled to the first driving member and a first cleaning pad coupled to the first rotating member. The first cleaning pad may have a cylindrical shape and may have a plurality of pores defined therein.

One of the problems is to provide a solvent composition which has a little adverse effect on the global environment and has excellent stability when a compound having a perfluoropolyether (PFPE) group is in a solution state. In an embodiment, the problem is solved by providing a solvent composition for dissolving a compound having a perfluoropolyether (PFPE) group includes Z-1,2-dichloro-3,3,3-trifluoropropene (1223xd(Z)) as a main component.

Bioactive coatings that include a base and a protein associated with the base for actively promoting the removal of organic stains are provided. In aspects, bioactive coatings that are stabilized against inactivation by weathering are provided including a base associated with a chemically modified enzyme, and, optionally a first polyoxyethylene present in the base and independent of the enzyme. The coatings are optionally overlayered onto a substrate to form an active coating facilitating the removal of organic stains or organic material from food, insects, or the environment.

Detergent compositions effective for controlling hard water scale accumulation are disclosed. Detergent compositions employing phosphinosuccinic acid and mono-, bis- and oligomeric phosphinosuccinic acid (PSO) derivatives with alkali metal carbonate and/or alkali metal hydroxide reduce had water scale accumulation on treated surfaces at alkaline conditions between about pH of 9 and 12.5. Methods employing the detergent compositions and preventing hard water scale accumulation are also provided.

According to embodiments of the present disclosure, an aqueous solution for cleaning glass articles may include, water; at least one of hydrochloric acid, nitric acid, phosphoric acid, an organic acid, and combinations thereof; and at least one of: a positively charged surfactant, and a metal salt. The aqueous solution may include from 0.01 wt. % to 1 wt. % of the positively charged surfactant, based on the total weight of the aqueous solution. A concentration of the metal salt in the aqueous solution may be from 0.1 M to 1 M. The aqueous solution may has a pH from 0 to 4.

An ice machine or ice maker is configured to produce ionized alkaline ice by having water pass through a medium which causes the water to become ionized. In certain embodiments, the medium contains group II elements, rare earth minerals, metal reducing agents, mineral buffers. The medium may be in a filter with the water passing through the filter to produce ionized alkaline water. The ionized alkaline water is then frozen by the ice machine or ice maker to produce ionized alkaline ice. Exposure of the water to magnetic forces may assist in the production of ionized alkaline water.

Disclosed herein is a multi-purpose cleaning solution, wherein the solution comprises vinegar, ammonia, alcohol, and a surfactant. Ammonium acetate forms in the chemical reaction. The multi-purpose cleaning concentrate can be diluted with water.

According to the invention, the compositions and methods provide for the complete removal of labels, synthetic glues and/or adhesives from a plurality of surfaces through the use of an aqueous or non-aqueous basic organic solvent and/or an amidine, optionally in combination with surfactants, chelants, acidulants and/or additional bottle wash additives. Beneficially, the compositions and methods are suitable for use at lower temperatures and pH conditions, along with under caustic-free and/or reduced caustic conditions to effectively remove such labels, synthetic glues and/or adhesives from a surface within less than about 30 minutes.
