i have had a shag rug for more than a year and the area my kids love to sit it is all smooshed down.....even when i vaccuum...The area under my coffe table is like it used to be when i vaccuum. how can i make it pop back up like it used to?
Vacuums can pick up all the loose dirt, but some of it gets matted into the carpet fibers and eventually weighs them down. Rent a steam cleaner or rug shampooer or have a professional company do it for you and you will be amazed at the results. Carpet should be cleaned once a year or every other year depending on the traffic they get - sounds like yours needs it once a year.
on top of that- using a leaf rake helps to flff it back up.
i have heard of wetting the rug and using a wide toothed comb with rounded ends, you can really detail it that way.
