Compositions and methods of the invention are directed to the removal of solid films, and particularly paint layers, from substrates, and particularly smooth, porous, and/or mineralogically fragile substrates such as sandstone. The compositions include cooked aqueous solutions of starch. The compositions can advantageously remove paints and other unwanted solid films from these and other substrates without damaging the substrate itself.

Powder and cast solid alkaline cleaning compositions are disclosed. Powders and/or solidification of a highly alkaline detergent composition are provided including sodium hydroxide beads and/or liquid and sodium carbonate in combination with water conditioning polymers. Methods of cleaning for soil removal of baked on, greasy soils, including those found in ovens, are also disclosed.

Described herein are compositions and methods for use in automotive care. The present disclosure includes compositions directed to, for example, a wheel cleaner.

An article is provided including an aqueous liquid detergent, and a package for the aqueous liquid detergent which is in direct contact with the aqueous liquid detergent, wherein the package is formed from a water-soluble, film-forming material. The aqueous liquid detergent includes at least about 40% by weight of water based on the total weight of the aqueous liquid detergent, a builder comprising potassium carbonate, wherein the potassium carbonate is present in an amount of at least about 25 weight percent, based on the total weight of the aqueous liquid detergent, a first surfactant, wherein the first surfactant is an anionic surfactant, and a second surfactant, wherein the second surfactant is a nonionic or an amphoteric surfactant. The first surfactant and the second surfactant are present in a combined total amount of about 0.1% to about 25% percent by weight based on the total weight of the aqueous liquid detergent.

A method of cleaning a contaminated surface, such as cleaning the elongate interior lumen of an endoscope contaminated with flesh, bone, blood, mucous, faeces or biofilm, said method comprising the steps of: providing a suspension of solid particles in a liquid to said contaminated surface, and flowing said suspension along said surface thereby to remove contaminant from the surface. The suspension is preferably a paste, where the solid material may be e.g. crystals of a salt, silicon oxide or organic material. The paste preferably has a solid fraction between 5 and 55%. A rheology modifier may be present.

A water-soluble unit dose article that includes a water-soluble film and powder composition, where the powder composition includes a) an acyl hydrazone bleach catalyst; b) from 1% to 10% by weight of the composition of an alkali metal carbonate; c) from 5% to 20% by weight of the composition of an alkali metal bicarbonate; d) from 5% to 20% by weight of the composition of an alkali metal silicate; e) from 5% to 20% by weight of the composition of an alkali metal sulphate.

In accordance with one aspect of the present invention, a method for cleaning a cooking chamber is provided. The method comprises applying a cleanser composition and water to the cooking chamber followed by incubating the cooking chamber. The cleanser composition comprises components that aid in loosening soil and debris during the steam cleaning and also provides a pleasant aroma. The cleanser composition aids in loosening soil and debris by effervescence.
