Stop dirt at the door: Preventing dirt and grime from getting on the carpet in the first place is a great way to keep it clean. The following helpful hints can stop dirt in its tracks.
Use mats: Outdoor and indoor mats or runners can reduce the amount of dirt that enters the house.
Take off your shoes. You can save wear and tear on carpet by asking everyone to take off his or her shoes before entering your home.
Change your air filters. Change air filters in your heating and air-conditioning systems as recommended by the manufacturer’s directions. The more dust and particles removed by the filter, the less that fall on the carpet.
Occasionally move heavy furniture. Moving your furniture on occasion won’t just renew the feel of your room, it will also help avoid excessive pile crushing. To remove a dent caused by heavy furniture, stroke carpet with the edges of a coin. You can also use a hair dryer or a steam iron to gently raise the dented area while you tug upward on the tufts. CAUTION: DO NOT LET THE IRON TOUCH THE CARPET.
Consider using carpet protectors under the legs of tables, chairs, and other furniture to help distribute the weight. Damage can occur if you use chairs or appliances with rollers or casters without a chair pad designed specifically for carpet.
Reduce periods of direct sunlight. Protect your carpet from prolonged periods of direct sunlight with blinds, shades, or awnings.
Use scissors to clip sprouts and snags. Do not pull them or you may damage the carpet.
Consider professional cleaning every 6-24 months. This depends on traffic and other use factors (kids, pets etc.), frequency of vacuuming and whether the carpet is a light or dark color.
