Abstract
A method for cleaning and restoring a hydrophobic effect of textiles in a domestic washing machine in which hydrophobic substances dissolved in the washing liquid are contacted with the textiles during a treatment process. A washing process for cleaning the textiles while adding a special detergent is carried out in the presence of an inflow of fresh water, and at the end thereof, the used washing liquid is pumped off. The soapy water used for the preceding process is replaced and a multi-stage rinsing process is carried out for the textiles. After termination of the rinsing process, the last rinsing water is replaced and the hydrophobic substances are added to a newly supplied amount of fresh water, and a treatment process for waterproofing the textiles is carried out in an additive-containing washing liquid and the used additive-containing washing liquid is removed without repeating the rinsing process.
