Abstract
A fairly constant concentration of detergent product in the wash liquor in a dishwashing machine can be obtained by using a sachet containing 20-350 grams of both detergent powder and one or more solid detergent briquettes, the weight of each briquette being in the range 1-100 grams and the total weight of the briquettes being 10-200 grams. When applying this sachet the need for extra detergent dosing in between consecutive washes to compensate for the dilution effect of rinse water is eliminated. The sachet is especially useful in industrial ware washing machines.
