With so many carpet cleaning vendors available, it's tough to choose a good one. The best method, however, has proven to be word-of-mouth advertising. Most services are equipped to fulfill all needs and specifications. They can be enlisted for vacuuming, shampooing carpets, bonnet cleaning, steam cleaning and dry cleaning. They can also be enlisted for stain removal and restoration.

In the absence of a recommendation make your choice based on an interview with a carpet cleaning professional rather than a customer care representative or a sales representative, and request a demonstration in you presence. Also, request client feedback, and if possible, inspect carpets the vendor has cleaned.

Ask questions about the method that will be used and a detailed description of the process. Also ask to inspect the equipment and read the user's manual as well as the fine print on the cleaning supplies. It is also a good idea to consult the manufacturer of the carpet so that there is a consensus on what's best for cleaning.

Additionally, a service that provides a follow-up service after the first round of cleaning would be a good choice, as it reveals the commitment of the service. Sometimes, a carpet cleaning service provides additional options such as de-humidifiers and disinfectants. These should also be inspected before use. In order to impress clients, services sometimes use 'brighteners' after cleaning. These may temporarily seem to add 'brightness' to the carpet but are usually harmful. Therefore, while our carpet is being cleaned, we should be attentive and inspect the cleaning agent being used. This will help us to ensure that the carpet is not damaged.
