For the permanently fitted carpets, (wall to wall), our technician group goes on the spot; in order to clean them,( in situ) with injection- extraction washing machines of special biodegradable- ecologically friendly detergents and dry foam. The drying time varies from 4-10 hours. The way of cleaning is as follows. First of all the operator of the machine uses the method of “shake-drain” to remove any sandy dirt (dust, pollen etc). Then, once identified by the technician, the dirt is being removed (using the appropriate hardware)or any bold stains are being removed as well. The final phase is, to perform the basic cleaning process (usually injection-extraction)i.e, to continue the washing cycle, with moist applied on the surface of the carpet. In some cases where we want very fast drying we can apply the method of dry foam also.
