A scale remover that efficiently removes scale deposited inside a boiler without corroding a boiler includes polyacrylic acid and polymethacrylic acid and/or salts thereof.

Disclosed are methods for using a composition comprising HCl, urea, complex substituted keto-amine-hydrochloride, at least one alcohol selected from the group consisting of isopropyl alcohol and propargyl alcohol, an ethoxylate, and at least one ketone selected from the group consisting of methyl vinyl ketone, acetone, and acetophenone.

The present invention relates to a method for substantially nickel-free phosphating of a metallic surface, wherein a metallic surface is treated one after the other with the following compositions: i) with an alkaline, aqueous cleaner composition which comprises at least one water-soluble silicate, and ii) with an acidic, aqueous, substantially nickel-free phosphating composition which comprises zinc ions, manganese ions and phosphate ions.

The invention also relates to the above cleaner composition itself and also to a metallic surface phosphate-coated by the above method, and to the use of said surface.

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.

Alkaline cleaning compositions with a blend of an amine and a nonionic alcohol ethoxylate between about 1:2 to about 1:10, preferably about 1:5 to about 1:10, with an alkalinity source and chelant are provided. The cleaning compositions provide efficacious cleaning of fatty soils to enhance fatty soil removal. Methods of cleaning surfaces using the cleaning composition are also disclosed.

A fuel injector cleaning system includes an injector cleaning housing that defines a cavity structured to receive a fuel injector. A heater is operatively coupled to the housing. A three-way valve includes a first inlet fluidly coupled to a calibration fluid reservoir, and a second inlet fluidly coupled to a cleaning fluid reservoir. An intake line includes a first end fluidly coupled to an outlet of the valve, and a second end structured to be fluidly coupled to a fuel inlet of the fuel injector. A controller is operatively coupled to each of the heater and the valve. The controller is structured to actuate the valve so as to cause flow of a cleaning fluid to the fuel injector. The heater is operated so as to heat the cleaning fluid. The valve is actuated so as to cause flow of a calibration fluid to the fuel injector.

A composition and method of treatment for handling potential prion contamination of surfaces is disclosed. The products include and the treatment uses products that include at least one prion digester enzyme selected from a serine protease in solution with a non-ionic surfactant, a hydrotrope and high purity water

The present disclosure relates to compositions, systems and methods for removing iron sulfide scale from a solid object, such as an oilfield component. The compositions include a carbon-carbon (CC) double bond with an electron withdrawing group bonded to at least one of the double-bonded carbons.

A catalyzed highly alkaline cleaning composition for cleaning stainless steel and other surfaces, namely those treated in clean-in-place processes, is disclosed. The composition comprises gluconic acid or salt thereof (e.g. gluconate) to serve as a corrosion and stain inhibitor for the high alkalinity compositions. The composition retains the cleaning and corrosion prevention properties of conventional clean-in-place solutions while being less expensive to produce.
