What are manufacturers guidelines for carpet maintenance?
Most manufacturers suggest vacuuming twice per week (more in higher traffic areas such as hallways, stairs, etc.) and having your carpet professionally steamed once a year. They also suggest that shoes never be worn on the carpet, and advise against bare feet. This leaves oily trails or matted areas, and in most cases crushes the fibers, making it impossible to clean or revive to the original condition of the carpet. Most carpet manufacturers normally require the above maintenance in order for their warranty to apply.
