Most homeowners treat an area rug the way they treat carpet. When it looks tired, they rent a machine or book the company that does the wall-to-wall. For an inexpensive synthetic rug, that is usually fine. For a wool, silk or handmade rug, it can do lasting harm.
The difference comes down to how each method handles water.
First, Know What Kind of Rug You Have
Before choosing a cleaning method, it helps to know what your rug is made of and how it was made. A few quick checks:
Look at the back. A hand-knotted rug shows the pattern clearly on the back, almost as sharp as the front, and the knots are slightly uneven. A hand-tufted rug usually has a canvas or cloth backing glued in place. A machine-made rug has a very even, grid-like back.
Check the fringe. On a hand-knotted rug, the fringe is the end of the warp threads that run through the whole rug. On many machine-made and tufted rugs, the fringe is sewn or glued on afterward.
Read the label. Many newer rugs list the fiber. Polypropylene, polyester and nylon are synthetic. Wool, silk, cotton and jute are natural. Viscose, sometimes sold as “art silk” or “bamboo silk,” is a plant-based fiber that is very sensitive to water.
Think about the price and origin. If you paid a few hundred dollars at a big box store, it is likely machine-made. If it came from a rug dealer, was a gift from overseas or was inherited, it may well be handmade.
How Steam Cleaning Works
A steam cleaner, also called a hot water extractor, sprays heated water and detergent into the pile and vacuums some of it back out. It was designed for synthetic carpet that is glued or stretched over a pad and cannot be removed from the house.
On a rug, three things go wrong:
- The water stays in. A machine recovers only part of what it sprays. A thick wool rug can stay damp at its base for days, which invites mildew and odor.
- The soil stays in. The heaviest grit sits at the bottom of the pile. Surface cleaning wets it and leaves it there.
- The dyes can move. Hot water and strong detergent can make colors bleed, especially reds and blues in handmade rugs.
There is also a fourth problem that often shows up later. Detergent left behind in the fibers is sticky. It attracts new dirt, so the rug looks dirty again sooner than before. Many homeowners notice that a rug cleaned this way seems to need cleaning more and more often.
How Hand Washing Works
A rug workshop removes the rug from the home and washes it as a whole object, front and back. The usual sequence looks like this:
- Inspection and dye testing. Each color is tested to confirm it will hold before any water is used.
- Dusting. Dry soil is shaken and vibrated out of the foundation first. This step alone can remove pounds of grit.
- Submersion wash. The rug is washed by hand in cool water with a pH-balanced soap made for wool.
- Rinse. Clean water runs through the rug until it comes out clear.
- Controlled drying. The rug is dried flat or hung in a ventilated room, then groomed.
The process takes longer. A week to ten days is typical, where a steam cleaning takes an afternoon.
Side by Side
| Steam Cleaning | Hand Washing | |
| Where it happens | In your home | At a workshop |
| Dry soil removal | Little or none | Thorough, before washing |
| Water temperature | Hot | Cool |
| Cleans the back | No | Yes |
| Rinse | Partial | Until water runs clear |
| Drying | On your floor, can take days | Controlled room |
| Time | A few hours | About 7 to 10 days |
| Best for | Synthetic, machine-made rugs | Wool, silk, handmade, antique rugs |
Which Rugs Need Which
| Rug type | Reasonable approach |
| Machine-made polypropylene or polyester | Steam cleaning or a hand wash |
| Wool, hand-knotted or hand-tufted | Hand wash |
| Silk or viscose | Hand wash by a specialist only |
| Antique or naturally dyed | Hand wash, after dye testing |
| Any rug with pet urine | Full submersion wash, since the odor sits in the foundation |
A Note on DIY Cleaning
Some homeowners try to wash a rug themselves in the driveway or the bathtub. For a small, cheap synthetic rug, that can work. For a wool or handmade rug, it is risky. A wet wool rug is very heavy and hard to handle without stretching it. Most homes have no good way to dry it flat and fast, and a rug left damp for days can develop mildew or dry rot in the foundation. Garden hoses and household soaps also cannot match the controlled rinse and pH-balanced products a workshop uses.
Between professional washes, simple care goes a long way. Vacuum with suction only, blot spills right away with a white cloth and plain water, and rotate the rug every six months.
What About the Cost?
A steam cleaning is usually cheaper per visit, and that is the main reason people choose it. But it is worth thinking about the full picture. A hand wash removes far more soil, so the rug stays clean longer and needs washing less often. It also avoids the risk of dye bleed and foundation damage, which can be expensive or impossible to fix. For a valuable rug, the slower method often costs less over the life of the piece.
Questions to Ask Before You Book
- Is the rug cleaned in my home or taken to a workshop?
- Do you test the dyes first?
- How is the rug dried, and how long does it take?
- Is the rug photographed and its condition noted at pickup?
- Are you insured for the value of the rug while it is in your care?
Rug Refinery, a SoHo workshop that has serviced more than 10,000 rugs, advises owners to be wary of any company that offers to clean a handmade rug in the living room. If the rug never leaves the floor, the soil at its base does not leave either.
The Bottom Line
A rug that cost a few hundred dollars and is made of synthetic fiber can be cleaned the convenient way. A rug you paid real money for, inherited or hope to pass on deserves a proper wash. The slower method costs more per visit, but it is what keeps a good rug in the family.
