The best preventative solution is to use walk-off mats at entrance areas. This will remove most soil from the shoes of people entering, if the mats are serviced regularly.
Improvements in carpet cleaning equipment, especially with the introduction of the “Truck Mounted Super Cleaners,” has resulted in probably the most commonly overlooked fundamental of all cleaning methods today – proper pre-cleaning vacuuming. Almost 80% of all carpet soil, even fine and particulate, can be removed with dry soil extraction; therefore, it seems ludicrous that so little attention is given to this important area. Vacuuming should be accomplished with good quality commercial vacuum cleaners and a power pile lifter. (Empty vacuum cleaner bags when no more than 2/3 full.) Pile lifters utilize two separate heavy duty motors. One motor drives the large cylindrical brush for superior agitation, pile restoration and grooming while another vacuum motor is used to provide proper airflow.
Always work away from power cords and insure that the plug is properly grounded. When pile lifting and/or vacuuming, it is important to pull the machine against the pile direction for optimum soil removal. Pile lifting is particularly critical in heavy traffic areas of commercial installations.
A good example of dry soil removal is a wet sand laden swimsuit. While the swimsuit wet, it is very difficult to shake out or remove the sand. Once the swimsuit has dried all that is required to remove the sand is just a few quick shakes. The dry sand is easily removed with very little effort. Properly maintained equipment is essential for good dry soil removal. Regular inspection and maintenance of filters, bags, belts and brushes will keep vacuum and pile lifting equipment in top operating condition.
