A neutralizer, destainer/descaling, and passivating composition and methods of using the same on metal surfaces are disclosed. The compositions are particularly well suited for the treatment of health care surfaces and other hard surfaces in need of treatment. In particular, the neutralizer, destainer/descaling, and passivating composition is an acid-based composition for use in instrument reprocessing.

Neutralizing instrument reprocessing

The present disclosure relates to a solid, enzymatic detergent compositions and methods of making and using the same. In a preferred embodiment, the detergent compositions are particularly useful for cleaning medical and dental instruments. In a preferred embodiment the compositions are particularly use for cleaning ware.

Solid enzymatic detergent compositions and methods of use and manufacture

In situ cleaning systems and methods of use are disclosed and provide cleaning use solutions with minimal chemical additives providing environmentally-friendly cleaning compositions. The in situ cleaning system provides one or more in situ cleaning components, including water treatment components, oxidizing agent generating component and/or alkalinity generating component, providing a cleaning use solution to a washing system.

In situ cleaning system

A cleaning composition is provided including an alkalinity source, builder, surfactant, water, a reducing agent and amylase in the ratio of from about 1:1 to about 1:3 wherein the total amount of amylase in the composition is equal to or less than about 1.0 weight percent; and wherein the composition is substantially free of polyols, alkanolamine, phosphates, and boric acid. A method of presoaking soiled substrates is further provided. The method including the steps of providing presoak solution to a soiled substrate at a temperature of between about 65.5&#xb0; C. up to about 80&#xb0; C., the presoak solution including the provided composition; draining the presoak solution from the substrate; providing a detergent to a soiled substrate including the composition of the present invention; and removing or draining the detergent; and rinsing the substrate with water.

Enzyme-containing detergent and presoak composition and methods of using

Methods for using in situ cleaning systems which reduce water hardness and minimize chemical additives are provided. According to the methods and systems, the methods of using may comprise providing feed water to an in situ cleaning system including water treatment components, oxidizing agent generating components and/or alkalinity generating components, contacting one or more articles with a use solution generated by the in situ cleaning system, and washing the one or more articles in a washing system. In addition to the methods of using, the systems for in situ cleaning are provided.

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.

Acid formulations for use in a system for warewashing

The invention generally relates to concentrated warewashing compositions and methods of using the same. In some aspects, the invention uses concentrated compositions in methods of warewashing where the concentrate is applied directly to the article to be cleaned, rather than dispensed into a sump and applied to the article as a ready-to-use composition. In additional aspects, the methods of using highly concentrated alkaline and/or acid compositions in an alternating pattern of alkaline-acid-alkaline or acid-alkaline-acid, or the like, provide substantially similar or superior cleaning efficacy while reducing the overall consumption of the alkaline and/or acid compositions.

Concentrated warewashing compositions and methods

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 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 in situ cleaning system provides an inlet capable of providing feed water to an in situ cleaning component, one or more in situ cleaning components, including water treatment components, an oxidizing agent generating component and/or alkalinity generating component, and an outlet in fluid communication with a washing system, providing a cleaning use solution to the washing system.

In-situ cleaning system

The present invention relates to cleaning compositions comprising conversion agents and methods of using them. The conversion agents of the present invention comprise water insoluble compounds such as metal oxides, metal hydroxides, and combinations thereof. The compositions can be substantially free of a builder, e.g., a chelating agent, sequestrant, and/or threshold agent, while still achieving effective soil removal.
