- ion exchange resins used by dishwashers to soften the wash and rinse water are saturated with calcium salts to render them inoperative. No regeneration salt of the resins is used for the washings.
- the program begins with a rinse with cold water for 10 minutes. After this rinse, a dose of 50 g of standardized soil is manually introduced into the dishwasher and 17 g of washing powder including the polymer to be tested. The washing then continues for one hour, after 30 minutes the temperature reaches 75 ° C.
- the water is drained automatically and a first rinse with water at 40 ° C is performed, followed by a second rinse with water at 70 ° C for
- the polymers are compared by visual inspection of the glasses placed next to each other in a black box illuminated zenith. A score of 0 to 10 is assigned at each examination of the glasses, 0 for a totally opaque glass and 10 for a new unwashed glass. The results obtained are shown in Table 3.
- the washes made using the compositions according to the invention make it possible to eliminate all the dirt. There is no continuous film of scale on the surface of washed dishes, especially on glassware, especially glasses. Washed dishes do not show any visible drip.
- compositions according to the invention allow an efficiency much higher than that obtained by means of the known sodium polyacrylate and of the same level as that obtained with the known sulfonated polymer.
