Disclosed is a method for treating a system, the method comprising providing 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; and inserting the composition into at least one of an oil well and a gas well.

A toilet that includes a bowl; a tank having a sidewall and a bottom defining a reservoir; a container located inside the reservoir and configured to contain a chemical compound that mixes with water to form a cleaning compound; a connector for coupling the container to the sidewall; and a flush valve. The connector has a bracket coupled to the container, a threaded protrusion that extends from the bracket into a hole in the sidewall of the tank, and a threaded fastener having a threaded body and a head, which is larger radially than the threaded body such that the head contacts an outside of the sidewall in a secured position in which the threaded body threads to the threaded protrusion. The flush valve is fluidly connected to the container to introduce the cleaning compound into the bowl through an outlet in the bottom during a cleaning cycle.

A toilet that includes a tank configured to hold water from a water supply; a reservoir fluidly connected to the tank and configured to hold a cleaning compound comprising a chemical compound and water from the water supply; and an actuator configured to control a flush cycle of the toilet upon a first activation, the actuator including at least one nozzle fluidly connected to the reservoir and configured to discharge an amount of the cleaning compound external to the tank upon at least one of the first activation or a second activation.

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.

A composition for cleaning hard surfaces includes from 3 to 20 wt-% dicarboxylic acid; from 3 to 25 wt-% surfactant; from 0 to 20 wt-% solvent; and water, and has a pH from 9 to 12.5. A ready-to-use solution of the composition includes from 0.1 to 5 wt-% dicarboxylic acid; from 0.1 to 5 wt-% surfactant; from 0 to 5 wt-% solvent; and water, and has a pH from 9 to 12.5. The composition is safe for use with calcite stone surfaces. A method of cleaning calcite stone surfaces comprises a use solution of the composition to the calcite stone surface, and rinsing, wiping, or scrubbing the surface. Another method of cleaning calcite stone surfaces comprises preparing a use solution by diluting the composition with water, applying the use solution to the calcite stone surface, and rinsing, wiping, or scrubbing the surface.

Methods and related systems include applying a first fluid to a hard surface, grinding the hard surface using at least one structured-abrasive pad while removing the first fluid, applying a second fluid to the hard surface, and scrubbing the hard surface using a floor bristle brush while removing the second fluid. Some surface enhancement compositions include a first nonionic surfactant including alcohol alkoxylate, a second nonionic surfactant including a different alcohol alkoxylate, and a third nonionic surfactant having an amide functional group. Other compositions include a nonionic surfactant having alcohol alkoxylate, a polymer, and a siloxane.

A cleaning composition for removing cement-based residues from tiles, such as cementitious grout used for installing flooring and for filling the joints is presented. The composition includes: sulfamic acid, a glycol solvent, and water.

A description is given of a composition comprising at least one isosorbide diester, at least one isosorbide monoester and at least one fatty acid, and also of a process for the preparation thereof. In addition, the present invention relates to the use of this composition as pearlizing agent and opacifier in cosmetic compositions and detergents.

Aqueous hard surface cleaner compositions useful for removing permanent ink are disclosed. The compositions comprise 75 to 99 wt. % of water; 0.1 to 5 wt. % of a monoterpene; 0.1 to 5 wt. % of a C.sub.10-C.sub.17 fatty acid derivative; and 0.1 to 5 wt. % of one or more surfactants. The fatty acid derivative is selected from N,N-dialkyl amides, N,N-dialkyl esteramines, and N,N-dialkyl amidoamines. Preferably, a base such as sodium carbonate or monoethanolamine is also included. The invention includes concentrates comprising the non-aqueous components recited above, as well as other applications for the cleaners and concentrates such as graffiti removers and permanent ink erasers. The combination of a monoterpene and certain fatty acid derivatives, especially fatty N,N-dialkyl amides, unexpectedly enables even dilute aqueous compositions to rapidly decolorize black permanent marker from hard, non-porous surfaces.

Disclosed is a system for removal of limescale from a surface, which provides a sheet infused with a descaling agent and a binding agent comprising a polyacrylate salt, wherein the polyacrylate salt causes the sheet to bind to a surface to effectuate removal of the limescale. In embodiments, the sheet may bind to a vertical surface for treatment of limescale.
