Our products crystallise during the drying process. Cheaper, traditional soaps and detergents are sticky. Residual levels of these inferior products stay attached to the carpet fibres. This leads to rapid re-soiling as dirt will then stick to these residues. Like how dish liquid becomes sticky around the lid. Using a quality crystallising product allows the tiny fraction of residual product to be released during normal vacuum cleaning. We provide a deep thorough clean that stays clean! Our regular customers are so pleased at how long their carpets stay clean.
