Once a piece of furniture sits for a long period of time in the same spot in a carpeted room, you may notice that it leaves quite an impression, literally. These impressions, or dents, are nothing more than crushed carpet fibres. Once something heavy sits on them, they lose their fluff and remain flat in the shape of the legs or base of whatever smashed them in the first place. Luckily, this is not permanent and you can fix these dents and fluff them up again.
Place an ice cube into the dent and let it sit and melt. Allow the melted water to sit in the dent for 12 hours.
Blot the water up with a towel. Soak up as much of the water as possible, using heavy pressure with your arms or your foot.
Fluff the carpet fibres back up with a spoon. Pull them gently to allow each fibre to stand in place instead of sticking together.
Set a clothes iron to medium and allow it to heat up.
Dampen a cloth with warm water so that it is wet, but not dripping. Place the cloth over the carpet dent.
Hold the iron in a hovering position a few inches over the cloth for about 30 seconds to a minute. This will create steam between the wetness in the cloth and the iron to allow the carpet to regain some fluff.
Scrape a coin over the spot to brush the fibres back into place. A spoon or your hands will work for this as well.
