Cleaning and degreasing compositions containing a diutan gum thickener are provided for removing burnt on, polymerized, carbonized food soils with minimum manual effort. The compositions are ready to use compositions and beneficially remain on a treated surface for sufficient time to permit soil penetration without drying out. The compositions can be easily removed with minimal manual effort, such as use of low pressure water applied to the treated surface, and beneficially do not leave residues. Methods for cleaning and degreasing a surface with the compositions are also provided. Thickening systems employing the diutan gum and laponite clays are also provided.

The invention includes a solid rinse aid that is particularly designed for pressed or extrusion solid formation and which is effective for spotless surfaces after rinsing, especially rinsing metals without corrosion. According to the invention, a solid acid is combined with a short-chain alkylbenzene and alkyl naphthalene sulfonate. The short-chain alkylbenzene and alkyl naphthalene sulfonate act as a solidification agent as well as a hydrotrope, and total dissolved solid (TDS) active and are combined with at least one nonionic low foaming surfactant.

Methods of acidic warewashing are disclosed. The compositions can include other materials including surfactants and chelating agents, and are preferably phosphorous free. Methods of using the acidic compositions in combination with alkaline compositions are also disclosed. Exemplary methods include using the acidic compositions together with other compositions, including alkaline compositions and rinse aids employed in an alternating alkaline/acid/alkaline manner. The methods also include acidic compositions that serve multiple roles.

The present invention relates to an etching cleaning composition and an etching cleaning method using the same. According to the present invention, the present invention has an effect of providing an etching cleaning composition capable of removing polishing residues generated when polishing surfaces where hybrid bonding between joints is required during semiconductor and display manufacturing processes and providing surface roughness and recesses appropriate for hybrid bonding; an etching cleaning method using the same; and a hybrid bonding material obtained using the same.

A hydrotropic composition is provided for surface cleaning that includes at least two hydrotropic compounds, an anionic surfactant, a nonionic surfactant, at least one cosolvent having a partition coefficient of log Kow of greater than 1. Water is present as the majority by weight of the hydrotropic composition and forming an emulsion. The hydrotropic composition may be formulated for use in a trigger bottle, aerosol, or wipe applications. A method of lifting stains with the composition is provided.

The present invention relates to a toilet cleaner comprising a cleaning agent, wherein said cleaning agent is included at a percentage between 50% and 80% by weight, and also comprising an effervescent agent at a percentage between 10% and 30% by weight. The cleaner is preferably in the form of solid granules, and it also comprises a foaming agent. The present invention allows providing a cleaner in solid form which can be applied directly in the toilet bowl and readily metered, giving the user a perception of cleanliness.
