Synthetic rugs tolerate hot water, alkaline pre-spray and vigorous agitation. Wool tolerates none of the three. The same method that restores a nylon rug will shrink, brown or bleed a wool one. That is why wool is quoted separately rather than priced per square foot.
Viscose is worse again, and shops sell it as "art silk" or "faux silk" to buyers with no idea what they own. Below: how to identify what you have, what each fibre needs, and what it costs on site.
Quick answer: Synthetic rugs clean on site at $0.75 to $1.50 per square foot. Wool needs cool water, neutral pH and fast drying, so it is quoted after inspection. Viscose and "faux silk" mark permanently with water. Send a photo of your rug.
Why Does the Fibre Decide the Method?
Wool is a protein fibre, closer to hair than to plastic. Three things harm it: alkaline chemistry, hot water that relaxes and shrinks it, and moisture that moves its dyes.
Synthetic fibres are plastics. The three common ones are nylon, polypropylene and polyester. They shrug off heat and alkalinity, hold dye tightly, and dry without changing shape.
Four things separate the two in practice: water temperature, pH, agitation and drying speed. A rug cleaned on the wrong side of all four does not recover.
| Fibre | Water | pH | Agitation | Drying |
|---|---|---|---|---|
| Wool | Cool | Neutral to slightly acidic | Gentle, no rotary | Fast, forced air |
| Nylon, polyester, olefin | Warm to hot | Alkaline pre-spray fine | Normal | Standard |
| Viscose, "faux silk" | Avoid water | Solvent methods | Minimal | Immediate |
| Cotton and jute | Cool, minimal | Neutral | Gentle | Fast, browning risk |
How Do You Tell Wool From Synthetic?
The feel test
Wool feels warm and slightly springy, synthetic feels cool and slick. Crush a corner of the pile: wool resists and recovers, synthetic flattens more easily.
The fringe test
On a hand-knotted wool rug, the fringe is the foundation coming out the two ends. On most machine-made rugs it is sewn on as decoration, and sewn-on fringe almost always means synthetic or a machine-made blend.
The back of the rug
Hand-knotted wool shows the pattern clearly on the back, with individual knots visible. A machine-made rug shows an even grid, often with a fabric backing glued on.
The price and origin
A rug bought for $200 at a big-box store is synthetic with very few exceptions. Anything described as Persian, Turkish, Afghan, Kashmiri or hand-knotted is wool until proven otherwise.
When it still is not clear, a fibre test settles it in under a minute. That test happens before any liquid touches the rug.
What Goes Wrong When Wool Is Cleaned Like Nylon?
Shrinkage. Wool and its cotton or jute foundation both shrink when soaked. A 9 x 12 rug can come back an inch or two narrower and never lie flat again.
Browning. Slow drying wicks tannins and lignin from the foundation to the surface over a day or two. The result is a yellow-brown cast that shows worst on light wool.
Dye bleed. Older and hand-dyed wool rugs carry dyes that move in water, so one red border runs into a cream field. Once it has moved, it becomes a restoration job.
Pile distortion. Rotary agitation flattens and twists wool pile, and the flattened area reads as a stain in daylight.
Odour that returns. Wool holds moisture for hours longer than synthetic. A rug that never dries fully develops the musty smell described in our guide to musty basement carpet.
What About Viscose and "Faux Silk" Rugs?
Viscose is the single most water-sensitive material sold as floor covering. It is cellulose, so water swells the fibre and it dries with permanent flat marks wherever the moisture sat.
Sellers call it art silk, faux silk, bamboo silk, banana silk or rayon. All five names describe the same fibre, and all of them behave the same way in water.
One spilled glass of water is enough to mark a viscose rug permanently. That is not a cleaning failure, it is the material, and no professional reverses it fully.
Three signs together mean treat it as viscose: silky and cool to the touch, a strong sheen, and a low price. The same logic applies to sofas, as covered in our guide to fabric codes.
What Does Area Rug Cleaning Cost in Niagara Falls?
| Rug size | Square feet | Synthetic, on site |
|---|---|---|
| 5 x 8 | 40 sq ft | $30–$60 |
| 6 x 9 | 54 sq ft | $40–$81 |
| 8 x 10 | 80 sq ft | $60–$120 |
| 9 x 12 | 108 sq ft | $81–$162 |
Rates run $0.75 to $1.50 per square foot, and every visit carries a $120 minimum. A 5 x 8 rug on its own is billed at $120, so most rugs are worth cleaning alongside a carpeted room or a sofa.
Wool, silk and specialty rugs are quoted individually after inspection. Four variables decide it: fibre, dye stability, foundation and how much soil sits in the base. None of them can be judged over the phone.
Two cases sit beyond on-site cleaning altogether: heavy soil deep in the foundation, and pet urine in wool. Both need a rug washed by full submersion, which we do not do. Where that is the answer, we say so rather than taking payment for a surface clean that leaves the problem underneath. Rates for carpet and upholstery are on the pricing page, and the process is on the area rug cleaning service page.
How Do You Look After a Rug Between Cleans?
Rotate it 180 degrees twice a year so traffic and sunlight wear it evenly. Vacuum wool without a beater bar, and never run a vacuum over the fringe.
Use a rug pad. One pad does three jobs: stops slipping, adds airflow underneath, and takes a share of the crushing that would flatten the pile.
Deal with spills immediately, blotting rather than rubbing, and keep water off anything you suspect is viscose. The ANSI/IICRC S100 standard covers area rugs as a separate category from wall-to-wall carpet for exactly these reasons.
Frequently Asked Questions
Can you steam clean a wool rug?
Wool can be wet-cleaned, but with cool water, neutral pH, gentle agitation and fast drying. Standard carpet settings shrink it, brown the foundation and can move the dyes.
How much does it cost to clean an 8 x 10 area rug?
$60 to $120 for a synthetic rug cleaned on site, at $0.75 to $1.50 per square foot. Every visit has a $120 minimum, and wool is quoted after inspection.
How do I know if my rug is wool or synthetic?
Wool feels warm and springs back when crushed. Check the fringe too: on a wool hand-knotted rug it is part of the foundation, while a sewn-on fringe usually means machine-made synthetic.
Can a viscose rug be cleaned at all?
Carefully and by low-moisture methods only. Water leaves permanent flat marks on viscose, and even a spilled glass can mark it, so anything wet is a professional decision.
Can every rug be cleaned in my home?
Most can. On-site cleaning suits synthetic rugs and lightly soiled wool. Heavy soil deep in the foundation and pet urine in wool need full submersion washing, which is a different trade and not something we offer.
