Move your furniture so that you can vacuum under it. Wipe down your baseboards and crevice vacuum while the furniture is moved. Do not drag heavy furniture across the carpet; Berber carpet could snag and run; the heat and friction generated by the dragging of the heavy pieces can burnish the tips of the all carpet fibers, leaving a permanent mark.
The warranties on most carpets require the carpet to be professionally steam cleaned (hot water extraction) every 18 months. Many people do this in the spring to rid the home of all the winter grime that has been tracked in. Make sure you are choosing a reputable carpet cleaner and save the receipt. If you ever have to file a warranty claim, the manufacturer will require proof of regular professional cleanings.
TIP: When you need to spot clean your carpet, first call the manufacturer of your carpet or the Carpet and Rug Institute to find out the appropriate product to use.

Many cleaning products can set in the stain, or worse, damage the carpet. You will find that if you have a relatively new carpet most stains come up with just plain water.
Check your exterior door mats and replace as needed.
Also check for any wrinkles, ripples, or buckles in your installed carpet. Call to have the carpet restretched as soon as you begin to notice any ripples.
TIP: Filtration soil is the dark or grayish lines on carpet along walls, stairways, or under doors. Changing the filters regularly on your HVAC system and using vacuums with good filtration systems can help prevent this problem.
