To clean a wool rug at home, vacuum it with suction only and blot spills right away with a white cloth and cool water. For a mark that stays, spot clean by hand with cool water and a little wool-safe soap, after testing it on a hidden corner. Every few years, have the rug washed by a specialist who cleans hand-knotted rugs by hand.

Wool rug care is easier than you might expect. Wool resists dirt and lets go of spills better than most fibers. A vintage rug has already had a long life, though, and its dyes deserve a gentle hand. Get the routine right and you will rarely need anything more.

How to clean a wool rug at home: start with vacuuming

Most wear on a rug comes from grit. Fine sand and soil work their way down into the pile. Every time someone walks across the rug, that grit grinds against the wool.^[1] Regular vacuuming lifts it out before it does damage, and it is the most useful thing you can do.

Use suction only. A rotating beater bar tugs at the pile, frays the fringe and can pull knots loose over time. If your vacuum has one, switch it off or raise the head to its highest setting. A plain suction attachment is even better.^[1] If you run a robot vacuum, see robot vacuums and wool rugs for the right settings.

Vacuum in the direction of the pile, not against it. Run your hand along the rug: the smooth way is the way the pile lies.
Go gently over the fringe, or skip it and shake it out by hand. Cleaning the fringe has its own tricks, covered in our guide to rug fringe.
Turn the rug over now and then and vacuum the back. This loosens grit trapped deep in the knots. It also disturbs clothes moths, which lay their eggs in dark, undisturbed wool.
Lift the rug from time to time and clean the floor underneath, where dust collects.

Shake or beat it outdoors

Small rugs clean up well with an old-fashioned shake outdoors. Pick a dry day. Drape the rug over a sturdy railing and give it a firm shake, or tap the back gently with a soft beater. Support its full weight so you are not straining the foundation. In a cold winter, cleaning a wool rug in the snow is another way to freshen one.

A small rug like this takes a shake well, with its weight spread along the rail.

Larger and older rugs are better left flat and vacuumed. A heavy rug should not hang from one edge, whether over a clothesline or on a wall. The weight pulls on the knots along that edge. If you want a rug on the wall, hanging it properly spreads the load across the whole width.

How to clean a large area rug

To clean a large rug at home, leave it on the floor and work in halves. Vacuum the face, then roll one half back loosely and vacuum the back of the rug and the floor beneath it, because grit collects there too.^[2] Repeat with the other half.

Move a big rug by rolling up one end and pulling gently with both hands, never by one edge.^[2] A full wash is the one job it cannot get at home, because it needs room to dry flat and fast.

Blot spills right away

With any spill, act fast and do not rub. Rubbing pushes liquid deeper into the pile. It can also felt the wool, matting the fibers together, and blur the dyes.^[3]

Blot instead. Lift off anything solid with a spoon first. Then press a clean white cloth or paper towel firmly onto the spill and lift the liquid away. Move to a clean part of the cloth and repeat until nothing more comes up. Work from the outside of the spill toward the center so you do not spread it.^[4]

Gentle, wool-safe cleaning, and a spot test first

If blotting alone does not lift a mark, try a mild solution. Stir a small amount of wool-safe detergent, the kind made for hand-washing sweaters, into cool water. Avoid ordinary dish soap and anything alkaline or with bleach in it.^[5] They can strip natural dyes and dull the wool.

Test before you touch the stain. Dab a little of the solution on a hidden corner or on the back of the rug.^[4] Then blot it with a white cloth and check the cloth for color. Vintage rugs often carry natural dyes that react to moisture, and this small step can save a rug.

If the test is clear, apply the solution sparingly with a cloth. Work from the edges of the mark inward, then blot dry. Blot once more with plain cool water to rinse out the detergent, because soap left in wool attracts dirt. The rug should end up barely damp, not soaked.

Dealing with pet accidents

Pet accidents need quick attention. Left alone, the moisture and acids can mark the dyes and soak into the cotton foundation. Blot up as much as you can right away with dry cloths, pressing hard to draw the liquid out of the pile. Follow with a light blot of cool water, and use the wool-safe solution above if you need more.

Be careful with enzyme cleaners and stain removers made for synthetic carpet. Wool is a protein fiber, and some of these products contain enzymes that break down protein.^[6] They can weaken the wool along with the stain, so test anything first. If a smell lingers after the surface is clean, the moisture has gone deep into the foundation. At that point the rug needs a professional wash, not more home treatment.

Can you put a wool rug in the washing machine, or hose it down?

Not a hand-knotted one. A washing machine folds and twists a rug while it is soaked, and a wet wool rug is far heavier than a dry one. The drum strains the foundation, pulls the rug out of shape and can make the colors run.

A pressure washer is worse. The jet drives water and grit deep into the base of the knots, and it can tear pile that is already worn low. A rug soaked right through also takes days to dry. That is how mildew and rot get into a cotton foundation.

A full wash of a wool rug, the kind that gets grit out of the base of the pile, is a job for a specialist. They wash rugs by hand and dry them flat, under control. It is also how every rug we sell is washed before it is listed. At home, stick to vacuuming, shaking and spot cleaning.

It was cleaned by hand and dried flat, which no washing machine can do for a rug this size.

Two other kinds of rug follow different rules. A tufted wool rug has its pile held in by glue and a cloth backing that water can loosen. Follow its care label; many say spot clean only. Machine-washable rugs are thin, usually synthetic, and made for the machine. Washable rugs vs wool rugs compares the two honestly.

Can you use a carpet cleaner on a wool rug?

We would not run a rental or home carpet cleaner, often sold as a steam cleaner, over a hand-knotted wool rug. It pushes hot water and shampoo into the pile and leaves some of both in the cotton foundation. Conservators advise against commercial carpet shampoos on good rugs, because the fibers attract dirt faster afterward.^[2]

Damp materials need to dry within a day or two, or mold can start to grow.^[7] If a carpet cleaner has already been used on yours, put a fan on it and lift a corner so air reaches the back.

How to clean a Persian or oriental rug

A Persian or other oriental rug is cleaned like any hand-knotted wool rug, since old rugs of this kind are most often wool knotted onto cotton or linen.^[2]

Spot test where a dark color meets a pale one, since a running dye shows there first. Shake the fringe out by hand rather than vacuuming it. Leave a rug with any silk in it to a specialist for anything wetter than vacuuming.

What to avoid

A few things do real harm to old wool:

Soaking. Too much water swells the cotton foundation and can make dyes run. A soaked rug also takes a long time to dry properly.
Hot water. Heat sets stains and can felt wool. Work with cool water.
Harsh chemicals. Bleach, ammonia and strong spot removers strip color and weaken the fibers.^[3]
Steam cleaners. Heat and moisture together are especially risky for old wool and natural dyes.
Hard scrubbing. It frays the pile and blurs the pattern.

Drying flat and out of direct sun

After any spot cleaning, help the rug dry evenly. Lay it flat and press dry towels onto the damp area to soak up what you can. Let air move around it. A fan nearby speeds things up. Keep it out of strong direct sun, which can fade the dyes unevenly.^[8] Do not walk on it or put furniture back until it is dry right through, pile and foundation both.

When to hand it to a professional

Home care handles the everyday, but some jobs need expert hands. Call a specialist for a full wash of a large or antique rug, a stain that will not budge, a flood, or a pet accident that has soaked through. The same goes for any sign of dye bleeding or damage to the foundation. Look for someone who washes rugs by hand rather than by machine. If a dry cleaner offers to take the rug, ask who will wash it and how.

Every rug we sell is washed and restored before it is listed, so it arrives clean. After that, most homes need a professional wash only every few years.

The routine that covers almost everything is short. Vacuum with suction only, blot spills the moment they happen, test before you clean, and never soak or scrub. If you have a question about a particular rug, our FAQ covers the common ones, or get in touch with a photo. If you are looking for a rug that arrives already washed, start with our full collection.

Cleaning is half the job. Protecting a rug from sun, pets and spills covers the other half, and why hand-knotted rugs outlast machine-made ones explains why the wool can take it.
