A detergent composition suitable for hand dishwashing and in particular for aluminium pan cleaning which has a pH of from 4 to 8.5 and consists of the following essential components: from 10 to 50% by weight of a detergent, from 5-40% of which is a calcium/magnesium sensitive anionic synthetic detergent; at least 1% of a solubiliser and 0.015-0.45% of an organic phosphonate. When used at dilutions of about 5x, the compositions can provide anti-resoiling effects on aluminium.

A dishwashing machine includes a dish loading station, a washing station and an unloading station. The washing zone is enclosed by a structure containing ingress and egress openings on both sides thereof for transfer of dishes into and out of the washing station. The loading and unloading stations flank either side of the washing station and contain transport racks for moving dishes in and out of the washing station. Each of the transport racks can function to either load or unload the washing s...

A dishwashing composition which can be used in the conventional manner to obtain good foaming and detergency and can also be used in dilutions of about 5:1 or less to obtain a non-stick effect on aluminium pans contains from 10-50% of a detergent of which from 5-40% is a calcium/magnesium sensitive anionic synthetic detergent, from 0.01-2% of a selected alkyl phosphate monoester, and from 1 to 40% of a solubilizer. An example of such a composition has the following formulaton:

A cleaning composition particularly adapted for washing dishes, glasses and silverware in mechanical devices such as automatic dishwashers and capable of inhibiting overglaze attack containing as an essential ingredient aluminum silicate.

In a dishwashing system, a dishwashing machine (10) is provided to wash a rack holding thereon tableware in a washing chamber, a wagon (W) is provided to have therein plural stages of horizontal storage shelves in an up-and-down direction, and an elevator (E) is disposed between the wagon and the dishwashing machine. On the elevator (E), a drive control device is provided to move a ramp (56) of the elevator by a driving mechanism (60) toward a position facing to one of shelves of the wagon after...

A dishwashing machine is provided for washing dishes with a very rapid washing cycle in which water and detergent are sprayed through different spraying nozzles in different operational stages within the dishwashing cycle.

The invention provides a dishwashing composition comprising builder material, buffer material and other conventional ingredients in combination with a lipase and a hydrophobic modified (co)polymer of acrylic acid. More in particular the invention provides a dishwashing composition comprising lipase (calculated as having an activity of 200 LU/mg) and a hydrophobic modified (co)polymer of acrylic acid in a weight ratio of 1 to 1:2.000, preferably 1 to 1:1 000.

The invention provides liquid automatic dishwashing detergents (LADDs) that contain a detergent enzyme and have a pH value less than 7.0. Such LADDs can lack phosphate builders, chlorine bleaches, and alkali, each of which is undesirable from the perspective of human and environmental safety. In addition, the invention provides methods for cleaning tableware.

The sprayer has, in the interior of the handle, a flow channel, in which the cylinder element is arranged. The piston is mounted in a freely displaceable manner in the cylinder element, and the cylinder element is open on the end side in the direction of the shut-off valve. The cylinder element and the piston bound, for example, an air-filled gas volume. If pressure surges occur when the shut-off valve is closed quickly, these pressure surges are damped by the piston moving in the direction of t...

Disclosed is a thixotropic automatic dishwasher composition having an aqueous solvent, a thickening agent, a source of chlorine, detergency levels of an anionic surfactant, builder salts and a buffer system to stabilize the chlorine source with the composition. The composition is dispensed by shearing the gel form of the thixotropic composition and thus having the composition develop the flow properties of a viscous liquid for the purpose of depositing the composition within the detergent compar...
