An area rug can be a nice addition to the decor of any home, but a crease in the rug can be not only an eyesore, but a tripping hazard as well. There are many suggestions on how to remove a crease or wrinkle in an area rug, but many either end up damaging the rug or just don't work. Here is one proven method that may help you.
Take a towel and run it through the washing machine.
Place the wet towel in the dryer just long enough for the towel to get warm, but not dry.
Place a dry towel over the wrinkled area on the rug.
Place the warm towel on top of the dry towel.
Place a heavy object on top of the towels to apply pressure, such as a small piece of furniture, phone book or even a few more area rugs.
Let the heat remove the crease. Repeat this process if necessary.
Do not place the wet towel directly on the rug, this may cause the colours to run.
