The word shampoo is on everyone’s lips in carpet cleaning and is probably the best-known term and process name. Every carpet cleaner offers you this carpet cleaning services for office. The basis of classic shampooing is a lot of foam. At the same time, a lot of foam also means a lot of surfactants. This is massaged into the carpet using a brush. The foam dissolves and binds a certain amount of dirt. In the second step, the dried foam is sucked off after a short drying time.
The consequences of shampooing are few and anyone for this process will only spray clear water on this carpet, so no cleaning agents were added. Nevertheless, the carpet foams after being processed with the brush machine. The remaining cleaning agents from a previous cleaning by a competitor are responsible for the foam formation, which at the same time ensured rapid renewed soiling.
Another variant of shampooing is wrongly called combination cleaning. In this case, too, a lot of foam is used and in the second step the foam is cleaned with the loosened dirt in the clear water spray extraction process. So you try to rinse out the foam as best as possible using the spray extraction method with clear water. However, this is only possible to a limited extent. For cost reasons, the carpet is therefore only flushed through the surface. In order to completely remove all cleaning agents from the shampooing, the shampooed carpet would have to be rinsed several times with clear water using the spray extraction. But nobody does that, because the effort is immense. With this variant, too, considerable amounts of shampoo remain in the carpet.
