The most compelling of all advancements in Carpet Steam Cleaning Melbourne technology comes from the carpet cleaning chemicals. In particular many of these new chemicals use encapsulation technology. This process suspends the dirt and soil from the carpet and surrounds it. This suspended dirt is then removed by cleaning equipment. In previous years encapsulation has only been used with bonnet cleaning or dry foam but recently this technology has been extended to hot water extraction. Encapsulation chemicals clean better and help the carpets stay clean longer.
