Problems
It is one of the most common calls we get: "I had the rug cleaned and now it smells." Four things cause it, and none of them is mysterious.
Wool smells like wool when it is wet, and a rug that is wand‑cleaned on your floor stays wet for two or three days. The smell fades as it dries. If it does not, one of the next three is the cause.
The pile dries; the cotton foundation underneath does not, and it starts to mildew on the back within days. The musty smell that arrives a week after a floor cleaning is mildew. The fix is a proper wash with a centrifuge and controlled drying, which is why rugs at the Farmingdale plant go home dry to the foundation.
Carpet shampoos and spot cleaners left in the pile smell of perfume at first and then of sour soap, and they attract soil so the rug greys quickly. The fix is rinsing until the water runs clear, which a wand cannot do.
The most common of all. Urine salts in the foundation are dry and quiet until water hits them; a surface cleaning wets them, and the rug smells of ammonia the next day, then every humid day after. Surface cleaning cannot remove them; a decontamination soak can. Our guide on why urine comes back explains it.
Get the rug off the floor and air it flat, both faces, so the foundation can dry. Do not spray anything on it. Then have it washed properly: dusted, immersed, rinsed clear, spun and dried flat. The smell has a source, and the source comes out in the wash.
Drop‑offs welcome any day; call ahead and you can watch the dye test.
Wet‑wool smell, yes, in a few days. Mildew, residue and urine smells do not; they need a full wash.
It masks the smell for a few days and adds residue. It does not remove the source.
Have the rug washed at a plant rather than on the floor; a plant‑washed rug goes home dry and rinsed clear.
