The invention relates to the field of removing various types of deposits from a surface, specifically to means for cleaning metallic and ceramic surfaces of industrial equipment, and can be used for removing deposits, such as oxides of metals (iron, chromium, nickel, etc.), carbonate and salt deposits, asphaltene-resin-paraffin deposits and deposits of a petroleum nature, and deposits of an organic and biological deposits. The proposed solution for removing various types of deposits contains hydrogen peroxide, complexone, an anti-foaming agent, water-soluble calixarene and water in the following ratio: hydrogen peroxide, a catalyst for decomposing peroxide compounds, an antifoaming agent, complexone, water-soluble calixarene and water in the following quantitative ratio: 2-35% by mass of hydrogen peroxide; 2-20% by mass of a catalyst for decomposing peroxide compounds; 3-10% by mass of complexone; 0.1-5% by mass of surface-active agent; 0.01%-1.0% by mass of anti-foaming agent; 0.01-1% by mass of water-soluble calixarene, with the remainder being water. The technical result is an increase in the effectiveness of action of a solution (degree of cleaning) for cleaning surfaces soiled with deposits having a high content of organic substances, while simultaneously extending the field of use of said solution.

A method of washing dishware in a dishwasher comprising the step of delivering into the dishwasher: a) a first composition comprising oxygen bleach and substantially free of enzymes; followed by b) a second composition comprising enzymes wherein the first composition has a pH of at least 11 and the pH of the first composition is at least 1 pH unit greater the pH of the second composition wherein the pH is measured at wash concentration at 20 C.

A device for removing oxidizable stains includes a device body having an opening and an internal space disposed therein. The device body includes a wall that at least partially surrounds the internal space. At least part of the wall is a flexible wall. A frangible wall separates the internal space into a first chamber and a second chamber. One or more solid components are disposed in the first chamber and include an active oxygen component. Water is disposed in the second chamber. A bleach activator component forms part of the one or more solid components or is included with water. The device is configured such that when a force is applied to strain the flexible wall, the frangible wall breaks to allow contact between water and the one or more solid components to form a peracid solution.
