Even though vacuuming can remove most of the dry soil, it is also necessary to clean your carpet on a regular basis to remove the oily, sticky soil that builds up in the pile as a result of cooking vapors, air pollution, and tracked in dirt. The particles of oily soil deposited on carpet fibers can cause gradual but significant dulling of delicate carpet colors; the color isn’t lost but hidden under the film. If this type of soil is allow to accumulate, it begins to attract and hold the dry soil. For this reason, cleaning is so important when the dulling of the carpet is first noticed.
If carpet is cleaned before it becomes too unsightly, the cleaning chore will be easier and more successful. It is a myth that cleaning the carpet before it is absolutely necessary will cause it to get dirty faster. Carpet in a typical household should be cleaned every 12-18 months depending on the number of residents and the amount and type of activity. Choice of proper cleaning systems is very important.
