Indentations

You will need a steam iron, a low sodium club soda, and clean white cotton towels. Pour club soda in the iron just like you would water, and heat the iron. You can use the high steam setting or slowly work the temperature up to whereever you are comfortable. Sprinkle the carpet with club soda until it's fairly moist. Place a white towel (use clean white cotton towels only!) over the area and iron. Check the area every minute or so to see if it is re-fluffing. This method will remove certain stains as well. It may take re-wetting the area and going over it a few times, so make sure to give it time to work. Empty the iron afterwards to remove the soda. 

Burns

Very little can be done. Small ends of blackened fibers may simply be clipped off with sharp scissors. More extensive damage may require replacing the area with a new piece of carpet. Installers do this with a "Cookie Cutter" that puts in a replacement plug.

Fuzzing

Fuzzing is different than shedding. Loose fibers still attached at one end. It's caused by fiber breakage, surface wear and the cutting of filaments by embedded grit. Vacuum often to get rid of grit. Carefully clip off fibers sticking out.

Shading

Normal traffic causes the pile of carpet to flatten slightly, resulting in a shaded effect, especially in plush carpet. Vacuuming the pile in the same direction will temporarily correct this situation. If two lengths of carpet are laid in different directions, more shading will occur by the seams. Only brushing and wear can lessen the look.

Even though a conscious program of vacuuming is followed, some change will take place. The changes will not only be in the traffic areas but in other section which receive very little traffic. This change is more noticeable on solid colors and in the better grades of plush carpet. It may first become apparent as a large spot, as if something has been spilled. It may look like a water spot. The spot may be rounded or have a wavy shape and not really enclosing any area. If your fingers are run over the spot, you will noticed that the pile runs in one direction until the edge of the spot is reached. The edge of the area will appear rough, or raised, and then once outside the area, the pile runs in a different direction from that in the spot.

Shedding

Dogs and carpets shed. No connection. Carpet, however, stops shedding or fluffing sooner than dogs. Fibers will surface that have been left in the carpet during manufacturing. This is not a defect, but a normal occurrence which is corrected by regular vacuuming.

Snags

Tufts that have pulled out of the carpet should be clipped off with sharp scissors. Never pull them. If a long "run" occurs, a carpet dealer can re-tuft or glue back yarn in place. Snags occur most frequently in loop pile constructions.

Sprouting

A carpet sprout is when one tuft is longer than the rest. DON'T PULL IT! Instead, trim it with sharp scissors to the height of the rest of the pile. Don't use a knife.
