This video is supposed to be an example of Upholstery shampooing, but it actually shows upholstery steam cleaning. As a professional upholstery cleaner in Tampa FL I clean upholstery every day. A lot of people get confused between steam cleaning and shampooing.
Upholstery cleaning with a shampooing method involves very little moisture and practically no dry time after cleaning, but it does have a few draw backs. Shampooing does not go below the surface of the upholstery and can give you a limited clean on heavily soiled fabrics. Steam cleaning, or hot water extraction cleaning is shown in the video above. It does involve more moisture and longer dry times but it can be more effective on medium to heavily soiled fabrics.
Upholstery shampooing has been around since the 1950's and involves applying a cleaning foam to upholstery and then brushing it into the surface to emulsify soils. Then it is dry vacuumed to remove the residual foam and dirt. It's a great way to maintain lightly soiled furniture but it can difficult to remove oil build up on thicker fabrics.
Upholstery steam cleaning starts with a pre-spray that is also brushed in to the upholstered surface. Then it is rinsed with hot water and vacuumed in one step, as seen in the video. If the steam cleaning is done with low pressure it will dry quickly and provide an excellent clean on heavily soiled surfaces. Either upholstery cleaning method will improve the cleanliness of your furniture, But I recommend steam cleaning your upholstery as my preferred method of cleaning.
