Carpet dents happen, particularly when heavy furniture has been placed on top of the carpet in the same position over a long period of time. These dents are called divots and happen when the delicate fibers in the carpet have been compressed. While not noticeable if the furniture remains on top of the compressions, they will show up if you rearrange furniture. Rubbing or vacuuming them usually do not do enough on their own. Fortunately, there are some tricks you can try to get rid of them!
Grab some ice cubes from the freezer and give carpet dents the cold shoulder! Place a cube or multiple ice cubes on the dent, depending on the size. Let the ice melt into the carpet for a few hours. The water will engorge the nap of the carpet and bring the height back up to the height of the surrounding areas. Blot up the excess water with a sponge and use a spoon or quarter to lift up any carpet fibers that are still hanging downwards.
2. Use a Towel
For really deep dents, put a damp hand towel or dish cloth over it. Set an iron on medium heat or on the steam setting and run it over the carpet for about a minute. Be careful not to touch the iron directly to the carpet since this could cause burn marks. Once you are done, vacuum over the spot to fluff it up.
3. Blow Dry
Your blow dryer can add volume to your carpet, just like It can do for your hair. Use a handheld hair dryer to restore carpet fibers that are limp. Start by spraying the dented area with just enough water to saturate the carpet fibers. Use the hair dryer to blow dry the damp area, fluffing up the carpet fibers with your fingers as you work.
If one of these tips does not do the trick, try it in combination with a different one.
To prevent any future dents, try moving furniture often. Moving furniture a few inches in one direction or the other can prevent the deep dents that are difficult to remove from forming. Carpet is much more likely to bounce back if the furniture has only been in one spot for a few months. Using furniture disks or larger pieces of wood under the feet of your furniture can also spread the weight of the piece over a wider area, leading to fewer dents.
