When Carpets are heavily soiled, hot water extraction is the most effective way to flush out all the dirt, grease and grime that builds up in the carpet fabric.
We use hot water extraction cleaning in combination with the dry foam method, the heavily soiled traffic areas are pre sprayed with hot water and cleaning solution, the machine is then passed over the area to add a cleaning foam, the brushes on the machine then scrub the cleaning solution,water and foam into a lather, the machine then sucks out the water along with all the dirt. This method of cleaning takes a little longer and is very effective at removing engrained Dirt.
With this method the carpets can still be walked on immediately, however drying time can be longer.
