Oriental Rugs Care

How to care for hand knotted oriental rugs

This article discusses long-term care and maintenance of hand-knotted (handmade) wool area rugs, including Oriental rugs and carpets. If you are dealing with an urgent rug accident. See if you can find a dealer near you that can pick up your carpet from your house.

People think that because Oriental rugs are valuable they must be pampered like fine China. But Oriental rugs have earned their reputation of being magical in part because of their sheer endurance. When they are dirty, they can be washed (unlike wall-to-wall carpeting, which can be surface cleaned only). And when they are injured they can be fixed. Their dyes resist fading and running, and their wool, full of natural oils, keeps many potential stains from penetrating and setting. We have seen that in the Middle East some new oriental rugs are thrown into the streets for “aging,” where they are driven over by trucks and camels alike. They come through the ordeal looking much improved. Oriental Rugs are, as they say, forgiving.

Still, rugs need a congenial atmosphere and a little attention to help combat their several natural enemies: sunlight, moths, carpet beetles and moisture.

Oriental Rugs Fade in Sunlight. Be Careful!

A congenial atmosphere includes protection from too much sunlight. After inspecting rugs in many homes over the years, I have come to think that sunlight may be a rug’s principal nemesis—even to be feared, even, than moths. Sunlight streaming through a window directly onto a rug is virtually guaranteed to harm it, whether morning or afternoon, southern or western sunlight. Naturally dyed oriental rugs and synthetically dyed oriental rugs suffer equally. Colors fade unevenly and wool and cotton dry out and become brittle. A good rug can be spoiled in a month or less.

Of course there are situations where the risk to your rug is less clear, like when it is in a sunny room yet does not take direct sunlight. Be careful. Some oriental rugs will take that much light and others will not—and there’s no way to know in advance which will and which won’t. It is possible and prudent to monitor your rug in this circumstance, which you may do by periodically comparing its colors on the front to those on the back of the rug. They should be the same. When colors are softer or lighter on the pile side of the area rugs than they are on the back, it’s time to take action.

You can eliminate or prevent the problem by keeping the curtains closed or by having your windows professionally coated with mylar (an invisible film which can be applied to your windows and which filters out harmful ultraviolet light). I must caution, however, that applying a mylar coating to certain windows may negate manufacturers’ warranties. Mylar has the secondary effect of taking a couple of degrees of heat off hot summer sun and softening glare through a window.

Most damage is caused by light shining through a window, of course, but often oriental rugs fade from sunlight streaming through a skylight. Sometimes people have no idea what’s happening because it occurs at a time of day when they’re not home. In my own house I once had to replace my Plexiglas skylight with Plexiglas that had been UV filtered. A special word of caution: don’t forget that if the sun is not coming directly through your window now, it may do so at a different time of the year when, for instance, the sun is lower in the southern sky.

If your oriental rugs have already suffered fading by the sun, there is still hope that it can be improved. If the fading is merely on the very tips of the pile (and you can determine that by looking closely at it), then washing the rug (professionally) may help the problem by simply abrading the faded tips of the wool. More severe fading can sometimes be improved by professional clipping of the entire pile. Occasionally oriental rugs are so faded that neither of these methods will work, and then one must decide whether to accept the rug as it is, or to attempt to fade the entire oriental rugs evenly. This involves leaving the rug in the blistering sun, covering parts of the rug that are already faded and leaving exposed the previously unfaded portions of the rug. How long do you leave it in the sun? Until the job is done. That might be three days and it might be three weeks. It is obvious, though, that one must be cautious with this approach lest you cook your oriental rugs too long.

Moths

The second major enemy of Oriental rugs is moths. The moths you need to worry about are small and hardly noticeable. They are the same moths that raid food in the pantry and wool clothes in the closet. They do their damage in the larval stage when, as (horror of horrors) little maggot looking creatures, they eat tracks in wool rugs. In rugs with wool foundations they often eat right through the rug, leaving behind a web-like material. Moths can cause devastating damage to oriental rugs in a matter of weeks. Here is some comforting news, though: moths rarely infest rugs and carpets that are in regular use. They prefer to be undisturbed, and they seek out oriental rugs that are stored or are under furniture. They also appear to prefer dark places. So a rug that is walked on and vacuumed or swept is hardly at risk at all, except parts of it that may be under a never-disturbed bookcase or bed.

Oriental Rugs or portions of oriental rugs covered by furniture must be disturbed from time to time to prevent moths from settling in. That means moving furniture off oriental rugs every several months or so and vacuuming or sweeping. When inspecting oriental rugs for moth activity, remember that most moth damage is to the back of a rug where moths are least likely to be disturbed. So examine the back of the rug along its perimeter and look for moths, moth larvae or the casing or webbing they leave behind.

You may elect to leave moth crystals in areas that are hard to get at, but remember that moth crystals lose their potency rather quickly. Oriental Rugs mounted on walls can attract moths because they typically are never disturbed. Check their backs in particular. I am now in the habit of handling oriental rugs mounted on walls as I walk past them just to make them inhospitable hosts for moths.

If, after all your efforts to prevent moth damage, damage still occurs, don’t despair. Your rug can be repaired. The question will be whether the value of the rug warrants the cost of repair.

Storing Oriental Rugs Safely

Stored oriental rugs are the most likely victims of moths, since in storage they usually are both undisturbed and in the dark. I would suggest that you store a rug in the following way. Moths seem to love dirty oriental rugs, so start with a clean rug if possible. I would roll moth crystals into the rug, maybe a fistful into a 4 by 6 foot rug. Some people object to the smell and toxicity of moth crystals. An alternative is to leave a rug in the sunlight for a half-day on both sides, hoping thereby to kill any moth eggs in the rug. A third alternative is to spray the oriental rug with a moth spray (Fuller Brush makes one) before you roll it. The smell from a spray seems to dissipate long before the smell of moth crystals does. Fold the rug, roll it up, and tie it. The next step is to place it in a heavy garbage bag, or a double or triple layer of bags and to seal it really well. If the carpet is too big to fit into a bag, use garbage bags on both ends and tape them together in the middle. An alternative is to wrap the rug in a heavy paper or plastic wrap, like Tyvac. In any case, the object is to seal them in some container unbreachable by moths (and, incidentally, by water). Finally, store the sealed rug where its wrap will not be pierced by something sharp and where the package will not be exposed to water or dampness.

An alternative to wrapping a rug for storage is storing it in a cedar closet or a cedar trunk. Natural resins in cedar wood repel moths. The advantages are clear: no chemicals are involved and no wrapping is required. There are two problems with cedar closets and chests, though. First, not everyone has them, and second, cedar eventually loses its anti-moth properties. My wife and I stored our collection of Oriental rugs in a cedar closet for many years without harm. Then suddenly the cedar lost its effectiveness and moths got in. I was told that sanding the cedar wood, which I did, might restore its aromatic quality. But I never again really trusted the closet. Cedar chips are sold which may be added to chests and closets. Perhaps they work, perhaps they don’t.

Carpet Beetles

Carpet beetle is not a great factor in the Western United States, but it is the scourge of East Coast rug owners. The adult is a small oval insect, dark with colored marks on the back, about a quarter of an inch long. Carpet beetles eat pollen and nectar, and often they are brought into the house on cut flowers. They lay eggs in dust and lint in dark, hard to access places. Both adults and larvae eat wool oriental rugs (and sometimes silk rugs), but most damage is done by the larvae. While moths eat tracks through wool rugs, carpet beetles eat right through the rug, cotton foundation and all. They leave behind bristly “shells” of shed skin. The best control is prevention through fastidious housekeeping and proper storage (see Storing Oriental Rugs above). Carpet beetles may be killed by freezing (-20 degrees F for three days), or through use of pyrethrin or other sprays.

Mildew and Dry Rot

When oriental rugs stay wet too long, they become mildewed and, eventually, suffer dry rot. The classic example is dry rot caused by a potted plant placed on a rug. The typical result is a horribly rotted circular area in a carpet that is otherwise in good condition. Don’t even think about putting a potted plant on a rug. No matter how clever you are, no matter that you use a glazed pot and a glazed saucer and you put a vapor barrier between the saucer and the rug, the rug will get wet and will stay wet unbeknownst to you and will become a rotten mess in an area about one foot in diameter.

Another typical situation comes up when oriental rugs are stored poorly, in a garage for instance, and they become wet without anyone realizing what has happened. Even though dry rot is not inevitable in such cases, a mildew smell is, and sometimes the smell of mildew simply cannot be removed. I have seen several occasions when moisture under a house has caused oriental rugs on the floor above to mildew.

Another common situation is for oriental rugs to be soaked by a leak in the roof or by a plumbing problem upstairs. In my first rug store, a stoppage in a main sewer line caused my toilet to back up, overflow and leave six inches of standing “water” throughout the showroom. (Isn’t it amazing that we somehow do get through life’s surprises? For the peace of mind of those who might have been my customers in those days, I had each rug washed thoroughly before they again became merchandise.)

Please do not worry needlessly, though. A little water on a rug, or even a lot of water, will not cause it to mildew unless the rug stays wet too long. For instance, oriental rugs one steps onto from a shower or bathtub rarely are hurt by water because they have time to dry out between times. And don’t panic if you spill a glass of water on a rug. Just dry it as well as you can with towels, and if it dries in several days, it will be all right.

Unfortunately, besides causing mildew and dry rot, water sometimes causes dyes in oriental rugs to bleed or run. All you can do in this situation is to get the rug dry as soon as possible, preferably with a water vacuum as outlined below.

If a rug is just a little wet, as from a spilled glass of water, do what I suggested above. Merely soak up as much water as possible with a towel or paper towel and everything will probably be just fine. If you are worried about the floor underneath, elevate the wet spot until it dries.

A rug that is thoroughly wet is another matter. The goal is to dry it before it mildews in about four or five days. If you have a Shopvac or other vacuum that will take in water, vacuum out as much water as you can. If not, lay the rug flat on its back outdoors and squeegee out as much water as you can. In a pinch, you can use the back of a garden rake as a squeegee. If you cannot do that (perhaps because it is raining heavily outside), then roll the rug tightly and stand it on end until water stops dripping out of the bottom end. If you have sunlight and a place to lay the rug, open it and let it finish drying outdoors. Or, if you know that the rug is dirty as well as wet, dry it enough so that you can get it to an Oriental rug cleaning specialist. If all else fails and the rug has been wet for four or five days and you have no prospects of drying it soon, spray it with Lysol. If you must dry a wet rug indoors, keep air circulating around it with a fan or hairdryer. Many a rug has come through seemingly hopeless situations and come out in good shape.

How to Keep Your Oriental Rugs Clean

Oriental Rugs gradually wear as they are walked on. That can’t be avoided, but you can lesson the problem by turning or rotating your oriental rugs from time to time so they don’t always get walked on in the same places. Walking on a dirty rug shortens its life prematurely. Dirt and sand fragments act like sandpaper as you grind them into the surface of your rug. How often should you have your Oriental rugs washed? On the average of every four or five years, but the real answer is that you should wash them when they are dirty and not before or long after. You can tell whether your rug is dirty by testing it with a white, wet cloth. Rub the rug’s pile vigorously with the wet cloth and check to see how much dirt is transferred to the cloth. Don’t worry about a little discoloration; any rug has a little dust on its surface. A dirty rug will transfer a lot of dirt to a cloth, and the results of your testing will be unambiguous. Dirty oriental rugs may not look especially dirty, but typically they look flat and lusterless.

Many Europeans are fearless about washing their own oriental rugs and have developed methods so hallowed by time that they are unquestioned. People of German origin have told me about their mothers turning oriental rugs upside down in the snow and beating them on the back. I have no doubt that the results can be quite dramatic when the rug is removed and an impressive amount of dirt is left behind on the snow. And the snow approach must do a good job of freshening the surface of an Oriental rug. But this approach can’t really compete with thoroughly wetting a rug and washing it with appropriate materials. I used to wash my own oriental rugs, and it can be done, but these days I let the professionals wash my oriental rugs. They do a better job than I do and they are better at dealing with color-run when that occurs.

Here is a summary of how oriental rugs are (or should be) washed professionally. (I would like to thank David Walker of Talisman in Santa Cruz, California for some of the information herein about washing oriental rugs.) First, as much dirt and dust as possible is loosened and separated from the rug before it is exposed to water. Some professionals use giant tumblers to accomplish this. Professionals test colors for fastness before they wet a rug to determine how they will approach the job. They may protect weak areas of the rug, perhaps by sewing gauze around them. If the rug’s dyes are stable and the rug can be washed, the rug is laid out flat and thoroughly wetted. Some experts filter chlorine out of the water. When the rug is wet, it is scrubbed by hand- that is, by brushes, usually on poles, operated by hand. Machines never should be used for the scrubbing. Rotary type machines often tangle the wool pile, and no machine can sense where scrubbing should be lighter or heavier depending on the condition of the rug.

The choice of a cleaning agent, of course, is critical. An unformulated (that is, neutral balanced) detergent is ideal, despite the old caveat that detergent should never be used on an Oriental rug. Conditioners may be added if wool is dry, and so may denatured white vinegar be added to stabilize the dyes. The rug or carpet is rinsed thoroughly and dried and then brushed down to soften and finish the rug’s surface.

Does that sound easy? How would you like to turn the hose on someone’s $30,000 antique Oriental rug? Good rug washers live with that kind of pressure every day and rarely have accidents. I have the greatest respect for the handful of specialists who are conscientious and who know what they are doing.

It is possible to freshen the surface of an Oriental rug without washing it. Simply sponging the pile with cold water will brighten it. You may also use the type of appliance made to clean carpeting at home, such as the Spray’n Vac. But do not use anything except water and a little denatured white vinegar (about a quarter of a cup in a gallon of water): no soap, no optical brighteners. You may clean a rug’s fringe with soap and water, but don’t bleach it.

Do not shake an Oriental rug to dust it. Do not beat an Oriental rug. You may use a vacuum cleaner, even a beater type vacuum, but be careful not to catch the fringe in the vacuum. You may also use a broom. Whatever you do to an Oriental rug should be appropriate to its condition. Don’t sweep a ninety-year-old, worn rug too vigorously.

Ends, Edges and Holes

Ends and edges are often the first parts of oriental rugs that need attention as oriental rugs age. It is critical to maintain them in good condition because problems with them soon lead to more expensive problems with the body of a rug. Typically, a rug’s fringe begins to wear away noticeably within 10 or 15 years from the time the rug was new and is nearly gone when the rug is 40-60 years old. Fringe can be replaced, though, often, new fringe on an old rug looks inappropriate. Many people who are accustomed to old oriental rugs simply get used to seeing eroded fringes and they don’t worry about it. Fringe is not structural, and your rug will suffer no harm from its absence. On the other hand, worn fringe is a sign that the end finish of the rug may be threatened by wear. Oriental Rugs are bound on their ends in a number of different ways, but each is designed to keep the foundation threads intact. When the foundation is frayed, a rug begins to lose its pile, and that requires expensive work. So, typically, a rug needs “end stopping” to secure the end from raveling, usually after something like 30 years.

Likewise, the edges of a rug, called selvages, need to be maintained. Selvages are wrapped with wool or cotton to protect the edges of the rug, and eventually this wrapping wears out and has to be replaced. This is routine work and not terribly expensive. To maintain a rug’s value it is important that a new selvage looks just like the old selvage: the same color, material and so on. Resist the temptation to replace the original selvage with a cheap, machine binding.

A variety of other problems that need repair may beset a rug during its lifetime: holes, wrinkle lines, curling edges, visible wear, moth damage and so on. There is nothing that cannot be fixed. The question always will be whether the value of the rug warrants the cost of repair.

The Controversial Practice of “Painting” Oriental Rugs

When a rug in need of repair is judged not to have enough value to warrant repair, an alternative to consider is having it “painted.” Painting is neither repair nor maintenance but is simply a cosmetic quick-fix. Painting is an emotionally charged issue because it has most often been used as a device to hide wear in order to sell a rug. Painting is just what it sounds like: textile dyes of appropriate colors are painted onto a rug, usually with a stiff paint brush, in such a way as to cover worn areas. Ideally the process is inexpensive and remarkably effective, sometimes making a badly worn rug look really good for another ten years. Eventually the paint wears off, so painting is never a permanent solution- except with a rug so worn that it will not survive the paint. Many people are opposed to painting, usually, as I have said, because its practice is often associated with dishonest rug dealers. Furthermore, a bad paint job can be quite noticeable and off putting. And finally, if the wrong materials are used, the “paint” can run when exposed to water and bleed into the rest of the rug. Some object to the idea of something foreign to the rug being added to it, and a few people simply don’t mind wear in Oriental rugs and would rather see wear than know their rug has been painted. One further objection: the value of some very desirable, collectible oriental rugs may be hurt by painting.

Having duly noted all these objections, I still submit that sometimes painting is a reasonable approach, especially when a rug lacks enough value to warrant repairing it properly. I say this knowing full well that by doing so I have just established myself as a butcher in the eyes of some

Should you use rug pads?

The people who live where Oriental rugs are made do not use rug pads under rugs, but it is customary there to remove street shoes upon entering a home. No one has ever methodically demonstrated that rug pads make rugs last longer, but clearly rug pads prevent many accidents by keeping oriental rugs and people from slipping around on hardwood floors. For that reason I usually recommend them. There is no need to have thick rug pads unless you especially want a cushy feel underfoot. Most likely your Oriental rugs will outlast its rug pad many times over. Pads tend to dry out and eventually they crumble. I have seen cases in which pads have discolored hardwood floors, especially when they have been used on newly finished floors that, presumably, have not had sufficient time to cure. Pads are now available that are designed to go between wall to wall carpeting and Oriental rugs. They are most effective if the carpeting underneath is not terribly long-piled. There are many products on the market, and you should ask your rug dealer for his or her recommendation.
