When people ask me what is the best thing to do to take care if their carpets (or rugs), I tell them frequent vacuuming. Based on a Proctor and Gamble Company analysis of carpet soiling in the US, about 79% of dirt in a carpet is dry particulate. The compensation of this dirt is about 55% from "Tracked-In" gritty particles (like sand and fine dirt), 12% from animal fiber from people, pets and fabrics and another 12% from fibers, indoor plants, and tracked in organic material.
Because most of this dirt is brought in from outside of the home, you should vacuum at least a minimum of 2 times per week.
