Abstract
Methods of cleaning an article in a dishmachine are disclosed employing a direct application of cleaning or rinsing composition to an article in a dishmachine for enhanced cleaning performance. The methods further beneficially provide a reduction in cycle time, water consumption and/or total concentration of the composition compared to conventional dishmachine usage applying the cleaning or rinsing composition from the sump of the dishmachine.
Claims20
A method of cleaning an article in a dishmachine (120, 200) comprising:
- applying a cleaning or rinsing composition (206A, 206B) directly to the article in the dishmachine (120, 200) with a contact time of about 1 second to about 15 seconds, wherein the direct application does not dilute the cleaning or rinsing composition in the sump (126) of the dishmachine (120, 200) before contacting the article;
- and
- optionally providing dwell time of about 1 second to about 15 seconds for additional contact time between the cleaning or rinsing composition and the article;
- washing the article in the dishmachine (120, 200) with water from the sump (126) in a wash cycle;
- wherein the cleaning or rinsing composition is dosed at a total concentration less than a cleaning or rinsing composition applied as diluted chemistry from the sump (126) of the dishmachine (120, 200) with improved cleaning or rinsing efficacy to methods employing the greater concentration of the diluted composition.
