Abstract: A cleaning apparatus is disclosed for extracting a liquid from a surface. The apparatus includes at least one extraction head that has at least one aperture that is facing the surface to be cleaned. The vacuum cleaner includes a vacuum pathway situated between the at least one extraction head and a riser that is connected to a vacuum motor. The internal surfaces of the vacuum pathway are smooth and the vacuum pathway has certain dimensions and orientations that optimize the extraction of a liquid from a surface.

Abstract: The present disclosure relates to a defoaming substance for defoaming an aqueous solution. The defoaming substance includes a defoaming agent and a carrier material intermixed with the defoaming agent to form a solid mass, the carrier material being at least minimally soluble in the aqueous solution. In one embodiment, the carrier material includes at least one type of organic acid. The defoaming agent may include at least one type of silicon-based defoamer. The present disclosure also relates to a method for making a defoaming substance. The method may include selecting a defoaming agent capable of hindering foam formation and reducing foam build-up in an aqueous solution, selecting a carrier material that is at least minimally soluble in the aqueous solution, combining the defoaming agent with the carrier material, and forming the combined defoaming agent and carrier material into a solid defoaming substance.

Abstract: The present disclosure relates to an anti-corrosion substance that includes an anti-corrosion agent and a carrier material. The carrier material is at least minimally soluble in aqueous solutions. An anti-corrosion apparatus is also disclosed, the apparatus including an anti-corrosion agent and a carrier configured to controllably exude the contained anti-corrosion agent. Also disclosed is a method for producing a block of anti-corrosion substance, which includes selecting an anti-corrosion agent, selecting a carrier material, combining the anti-corrosion agent with the carrier material, and forming the anti-corrosion substance from the combination of the anti-corrosion agent and the carrier material.
