  • Method of washing articles using a rotating drum washing machine
    Patent number: 5245722
    Abstract: The method for washing articles consists in introducing large elements into the machine drum with the articles to be treated, the elements having a flattened shape with rounded edges. Increasing the number of large elements and/or addition of an enzyme complex and/or a powder having similar properties and/or a material such a pumice results in premature (but controlled) wear of the articles to be treated. The invention considerably reduces the quantity of detergent products required for washing.
