Cross states that furniture cleaners often use dual methods of cleaning because they are concerned with the chemical reaction on delicate fibers and dyes; you can do the same for virtually any carpet, especially those with heavy, ground-in soils.
He notes that when using dual-method cleaning, a two-man team is a smart idea because it is difficult for one person to be cost-effective when having to switch from one cleaning method to another.
Cross adds that many cleaners are utilizing encapsulation preconditioners and rinses, which will result in a non-sticky residue that minimizes wicking problems.
According to Cross, the simple use of a carpet rake after applying preconditioner can easily double your cleaning results because the detergent effectiveness is increased and soil suspension is enhanced, making your hot water extraction — if that is your method of cleaning — much more effective.
