How wool, viscose, jute and synthetic rugs are cleaned

Why the fiber decides how a rug is cleaned

The Carpet and Rug Institute counts five main pile fibers in U.S. carpet: nylon, polyester, polypropylene (also called olefin), triexta and wool, with synthetics making up the vast majority. Each, it says, differs in durability, texture retention, stain and soil resistance, colorfastness and ease of cleaning. Rugs also come in plant and regenerated fibers, and WoolSafe calls those water-sensitive. Wall-to-wall carpet uses many of the same synthetics: how carpet is cleaned.

The WoolSafe Organisation, which approves cleaning products for wool, sorts the water-sensitive fibers into two groups: cellulosic, or plant-based, fibers such as sisal, sea grass and coir, and regenerated fibers such as viscose, Tencel and bamboo. The Federal Trade Commission’s textile rules, which set the generic names for manufactured fibers, define rayon as a manufactured fiber of regenerated cellulose and olefin as one made of a synthetic polymer at least 85 percent ethylene, propylene or other olefin units by weight, and allow the name triexta for a polyester whose glycol is at least 90 mole percent 1,3-propanediol.

Nourison, which makes rugs, repeats one instruction in each fiber section of its care page: use a professional cleaning service, since home cleaning methods are discouraged.

Wool: a wet clean, with the right chemistry

WoolSafe’s guide to cleaning wool asks for chemicals with low alkalinity and no added bleaches or dyes. Its reason: high alkalinity, often but not always shown by a high pH, can make dyed yarns bleed, bleed the pigment in natural Berbers, cause jute staining on the pile of light-colored carpet and, in extreme cases, yellow and weaken the wool itself. On wool and wool-rich carpet, it says, use only WoolSafe Approved chemicals.

Household products are out. WoolSafe’s consumer leaflet says never to use dish washing liquid, soap or other general household cleaners on wool: they may clean well enough, but they will almost certainly bring rapid re-soiling, color bleeding or damage to the pile or backing. It adds that the protective treatments many carpets come with eventually wear off.

Water still needs care. Over-wetting wool greatly lengthens drying and can discolor the pile, WoolSafe says, while low-moisture interim cleaning can leave a wool floor covering dry within an hour: drying times by method. Some loose fiber is normal too. Nourison calls pile shedding a normal trait of quality area rugs, particularly wool ones.

Can a viscose or jute rug get wet?

As little as possible. Nourison says moisture weakens viscose, so that rubbing a damp rug can break or damage the fiber, and that the wrong cleaning chemicals can easily stain and yellow it. With jute and sisal the issue is absorbency: plant fibers take up liquid and can shrink and pucker when wet or kept damp, and Nourison’s instruction for jute is no steam cleaning and no wet shampoo. A wet spill on jute should be dried at once with a fan or a hair dryer, it says.

WoolSafe’s rule for these water-sensitive fibers is to start with a low-moisture method, dry compound or encapsulation. Encapsulation means misting a product onto the pile, agitating it gently, letting it dry and vacuuming it away. Dry compound carries no danger of over-wetting, shrinkage or long drying, and the floor can be walked on almost at once. WoolSafe also warns against spraying a water-based spot remover straight onto a spot, which can distort the pile, leave a water mark and drive the spill deeper.

Two more cautions from WoolSafe. Too much protector can distort the pile on regenerated fibers and change, move or strip the color on plant-fiber rugs. And a heavily soiled fine-fiber rug that needs a restorative wet clean belongs with a professional who really understands those fibers, such as a WoolSafe Approved Rug Care Specialist.

Synthetic rugs: nylon, polyester and polypropylene

Shaw Floors’ comparison of its carpet fibers sets out how the synthetics differ. Nylon isn’t stain resistant by nature and relies on an applied stain-resistant treatment. Polyester is naturally stain and fade resistant, with softness and color clarity. Polypropylene resists stains and fading too, but is less resilient than nylon or polyester.

Shaw’s ratings table separates them on soil rather than stains: all three rate Excellent for stain resistance, but soil resistance runs Excellent for nylon, Fair for polyester and Poor for polypropylene, and texture retention Excellent, Good and Fair. Nourison groups these synthetics with wool in a single care section, with the same advice to use a professional. Triexta, the fifth of the main carpet fibers, is a kind of polyester under the FTC’s naming rules.

How often to clean a rug, and what it costs

The Institute of Inspection, Cleaning and Restoration Certification (IICRC) publishes a professional cleaning standard for carpets and rugs, ANSI/IICRC S100. By the American National Standards Institute’s summary, it calls for cleaning area rugs every 12–24 months, depending on where they lie and how much traffic they take.

A worked example, with its assumptions: an 8x10 wool rug is 80 square feet. At HomeAdvisor’s wool rate that is $240–$640, and hand washing would run $400–$640, against Angi’s size-based $150–$400 for an 8x10. HomeAdvisor adds that rug cleaning costs 25 to 40 percent more where the cost of living is high, naming New York City as an example. The visit builder adds a hand-washed rug at HomeAdvisor’s $5–$8 per square foot.

For Maid VIP, our affiliated partner, rugs are priced by size. The cleaning company confirms the price before any work, and area rug cleaning in Thousand Oaks covers the visit.

Santa Ana dust and the rugs by the door

Wind is the local twist. The National Weather Service’s glossary describes Santa Ana winds as strong, hot and dust-bearing, coming down to the coast around Los Angeles from inland desert regions, and the National Wildfire Coordinating Group lists them as a warm, dry, strong foehn wind. During the Woolsey Fire, the after-action report prepared for Los Angeles County records Santa Ana gusts of more than 50 miles per hour.

The U.S. Environmental Protection Agency notes that carpet holds material brought in from outside as well as what starts indoors, and two points in the S100 summary apply to the rugs nearest the door. The aim of maintenance is to keep soil out of the building and off the carpet, and an area rug’s interval depends on placement and traffic, so an entry rug that takes wind-blown dust points toward the shorter end of 12–24 months. Between cleanings, the EPA’s asthma advice is a weekly vacuum with a HEPA filter: carpet, dust mites and allergies. Ash after a wildfire is a separate case: ash and smoke indoors.
