Before we continue, remember that the mistakes discussed vary on the goal at hand whether it is maintenance, surface clean or deep carpet cleaning. Low moisture or encapsulation cleaning has its disadvantages too, as the chemical used can build up over time and degrade carpet’s appearance. In this process, the chemical is sprayed into the carpet and wait until the chemical crystallizes, or ‘encapsulates’ the soil it is laid over with. Using this method uses little water, compared to other methods such as hot water extraction carpet cleaning.
