The suggested way does not return the taharah of the place. Taharah is done with the use of water. After the removal of the najasah and if under-Kurr water is being used, the najis place should be washed twice, with the removal of the water after each time. This can be done by a piece of cloth or a mop or the like to soak it up. The collected water is najis so one should make sure that najasah does not spread because of it. A bucket or a large utensil can be used near the najis place to put the cloth with the najis collected water. If running water is used, it is enough to wash the place once with or after the removal of any traces of najasah. To be sure that the whole place is Tahir, all parts which are suspected to be najis must be made tahir.
