| Abstract: | Contributions on Mechanical Dish Washing 4: Removal of Complex Soils from Glass Surfaces Under practical conditions, the soil on household crockery is composed of a mixture of fat, starch and protein residue. These diverse components mutually affect their adherence, and, consequently the ability of the cleansing liquid to remove them. Removal of starch is improved in the presence of casein residues; conversely, casein is more easily removed from glass in the presence of starch. Starch residues inhibit the removal of fat, however, this negative effect is compensated, if casein residues are simultaneously present. An attempt is made to explain the interactions between the individual components of the soil. |
