This is one of many great acticles from a Home Inspector who is a member, as am I, of the Sustainable Building Coalition. Everyone with a Jacuzzi tub, sit up and take notes!

Question: How do you prevent bacteria buildup in Jacuzzi bathtubs? Is this a serious concern?
Answer: The main source of bacterial growth in whirlpool tubs is the residue that accumulates in the piping. These substances include soap film, body secretions, skin, hair, bath oils, and dirt. When these organic substances combine with minerals in the water, they congeal, forming a jelly-like matter that coats the linings of the water piping and other components of the whirlpool system. The warm, dark environment where this coating accumulates is an ideal location for the growth of infectious micro-organisms.
To eliminate this bacterial culture from your tub, it is recommended that the system be cleaned regularly. Be aware, however, that normal household disinfectants and cleaners - such as bleach, detergents, vinegar, or baking soda - are not completely effective in removing whirlpool contaminants. Instead, whirlpool manufacturers recommend operating the system for approximately 15 minutes with hot water and a solution of common dishwasher detergent. This has been found to be effective in dislodging contaminants. After draining, the system should be rinsed by operating the system with clear, cool water.
There are also various companies that provide professional cleaning of whirlpool systems, using specially formulated cleaners. The bottom line, however, is to be aware of possible health hazards and to clean your whirlpool system or have it cleaned on a regular basis. For further details regarding the proper cleaning and maintenance of your unit, contact the manufacturer.
