The acidic compositions are liquids that remove polymerized soils, hard water deposit (e.g., calcium carbonate), soap scum, rust and other stains (e.g., coffee and tea), including assisting in general cleaning of difficult soils, such as fats, oils, cosmetics, and other difficult soils. The acidic compositions can include at least one organic acid and a solvent or solvent system, and if desired, can be PPE free compositions. Methods for using the acidic compositions as pre-treatments, soaks and/or application in machine and manual warewash are also provided. Methods for using the acidic compositions for removing polymerized oils, carbonized soils, fats, oils, stains (e.g., coffee and tea), hard water scale/deposits, and cosmetics are also provided.

The disclosure provides cleaning compositions including at least one acid, at least one carbonate salt, at least one gum, at least one acid salt, and, optionally, at least one chelating agent. When exposed to an aqueous medium, the cleaning compositions may produce carbon dioxide. These cleaning compositions find use, for example, in cleaning textile fibers, such as carpets, drapery, upholstery, and the like. The disclosure provides methods of cleaning soiled textile fibers with a cleaning composition including gum arabic, at least one acid, and at least one carbonate salt.

A phosphate-free automatic dishwashing cleaning composition including: a) a protease wherein the protease is a variant having at least 60% identity with the amino acid sequence of SEQ ID NO:1 or SEQ ID NO:2 including two negatively charged amino acid residues, aspartic acid (D) and/or glutamic acid (E), in positions 124-131 using the SEQ ID NO: 1 numbering and the SEQ ID NO:2, respectively; and b) from 10 to 50% by weight of the composition of a complexing agent system comprising from 0 to less than 30% by weight of the composition of citric acid.

The detergent composition for metal product exhibits excellent detergency and metal corrosion suppressing performance.

A dishwasher composition includes at least one strong chelant, at least one weak chelant, at least one surfactant, and at least one enzyme. The dishwasher composition can be a liquid or a gel and has a pH of from 7.0 to 9.5 and may contain less than 1 wt. % silicates based on the total weight of the dishwasher composition. Methods of washing articles include preparing a wash solution that includes water and the dishwasher composition, and contacting at least one article with the washing solution during at least a portion of a wash cycle of a commercially-available dishwasher.

An automatic dishwashing composition is provided, comprising: a dispersant polymer blend, comprising an acrylic acid homopolymer; and a copolymer of acrylic acid and a sulfonated monomer; wherein the dispersant polymer blend has a blend ratio of the acrylic acid homopolymer to the copolymer of 3:1 to 1:3; a surfactant; a builder; and optionally, an additive.

A cleaning agent portion including a water-soluble wrapping and at least one composition for cleaning and/or caring for an automatic dishwasher, the composition containing at least i) an acid and/or ii) a buffer system consisting of at least one acid and at least one base, wherein the composition includes at least two parts, at least one part A being a compressed part and at least one part B being a non-compressed part or a further compressed part, an optionally compressed part B being compressed to a lesser extent than part A. The invention also relates to a method for producing the cleaning agent portions. The invention further relates to a method for cleaning and/or caring for an automatic dishwasher using the cleaning agent portion. The invention also relates to the use of and/or a method using the cleaning agent portion for cleaning and/or caring for an automatic dishwasher.

The present invention is directed to compositions, methods and systems for the removal of starch. The methods include: providing cleaning solution and rinsing fluid along supply line(s); connecting the supply line(s) to one or more cleaning applicators positioned to apply the cleaning solution or the rinsing fluid to one or more surfaces of a starch applicator system; and providing a controller which is able to control application of the cleaning solution and the rinsing fluid through the one or more cleaning applicators. The systems include the components described in relation to the methods. The compositions include about 5 to 15% w/w alpha amylase to break down the starch into water-soluble units; and non-ionic surfactant(s) and/or solvent(s) to react at the interface of the starch and surface it is attached to as well as liquefy the resins.

A cleaning liquid containing at least one surfactant (A) selected from the group consisting of a polyoxyalkylene alkyl ether phosphoric acid, a polyoxyalkylene alkyl ether acetic acid and a polyoxyalkylene alkyl ether sulfonic acid and a chelating agent (C), which has a pH of 8 or more, and a cleaning liquid containing an oxidizing agent (B) and a chelating agent (C), which has a pH of 8 or more.

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.
