FIELD: chemistry.SUBSTANCE: granular composition contains hydrophobic cellulose and/or silicated cellulose and a metal salt, such as an alkali metal salt. Preferably, the composition contains a metal salt and a cellulose component in equal ratios. The method involves the following steps: 1) depositing the granular composition onto the carpet; 2) facilitating contact between the cellulose-containing composition and the spot/dirt on the carpet; and 3) removing, at least partly, the cellulose-containing composition. Step (3) is preferably carried out using a vacuum cleaner.EFFECT: preventing damage to carpets and change of colour.11 cl, 24 ex |
