A Persian rug is hand-knotted from natural fibers and, very often, natural dyes, which means it behaves nothing like a synthetic rug when it gets wet. The way it is cleaned matters as much as how often. These are the questions Bay Area homeowners ask us most about Persian and Oriental rug cleaning: the right method, what it costs, how to tell what you have, and which popular home remedies do more harm than good. Our full process is on the rug cleaning page, and every rate is on our pricing page.

How Persian rugs should be cleaned

What is the best way to clean Persian rugs?

A professional hand wash, done in stages. This is the process we follow for every rug:

1. Inspection and fiber analysis. We identify the wool, silk or blends, the knotting and any existing wear, because a silk Tabriz and a wool Heriz should never be washed the same way.
2. Dye testing. Each color is tested for bleeding before any water touches the rug.
3. Dusting. Years of dry grit are shaken out of the foundation. This step often removes more soil than the wash itself.
4. Full-immersion hand wash. The rug is submerged and washed by hand in cold water with pH-balanced, fiber-specific soap; never steam, never harsh solvents.
5. Specialty treatment for stains, pet odors or moths, where needed.
6. Rinse and controlled drying. It is rinsed until the water runs clear, then dried flat in a temperature- and humidity-controlled room.
7. Grooming and inspection before it comes home.

The whole cycle usually takes 10 to 14 days, mostly because good drying cannot be rushed.

Can a Persian rug be steam cleaned?

No, and this is the single most common way we see good rugs damaged. Steam and hot water extraction can make natural dyes bleed into neighboring colors, shrink the wool and the cotton foundation unevenly so the rug no longer lies flat, set protein stains such as urine rather than removing them, and leave moisture trapped deep in the foundation, where it can cause odors or rot.

Persian and other hand-knotted rugs should be washed by immersion in cold water and dried carefully. We do not use steam or carpet-cleaning machines on fine rugs at all. If a rug has already been steam cleaned and the colors have run, some dye bleeds can be corrected after testing, so it is worth asking.

Can I clean my Persian rug myself?

You can, and should, do the routine care yourself:

• Vacuum regularly with suction only, no rotating beater bar, and avoid running over the fringe.
• Every few months, vacuum the back of the rug; the vibration loosens grit from the foundation.
• Blot spills straight away with a clean white cloth and cool water. Blot, never rub.
• Rotate the rug once or twice a year so it wears and fades evenly.

A full wash is a different matter. A wet Persian rug is very heavy, natural dyes can run, and a rug that dries slowly can develop odors, mildew or foundation rot. That part is best left to a specialist. See also can vacuuming too much ruin a rug.

How to clean a vintage Persian rug?

Carefully, and starting with an inspection rather than water. A vintage or antique rug can have weak spots in the foundation, loose fringe, dry or brittle areas and colors that have become unstable over the decades, so each of those is checked first and every dye is tested.

The rug is then dusted thoroughly, because old rugs usually hold a lot of grit, and washed gently by hand with the water, soap and handling adjusted to its condition. Weak areas are stabilised before or after washing as needed so the wash does not make them worse. What to avoid: home carpet shampoos, rented machines and anything hot. Damage to old fibers is very hard to undo, and a vintage rug that has survived this long deserves a gentle hand.

What it costs

How much does it cost to professionally clean a Persian rug?

Persian rug cleaning is priced by size, so the easiest way to estimate is to multiply length by width. Our published rate for Persian and Oriental rugs is $7.50 per square foot, and silk is $8.00 per square foot. Some typical sizes:

• 5×8 (40 sq ft): about $300
• 6×9 (54 sq ft): about $405
• 8×10 (80 sq ft): about $600
• 9×12 (108 sq ft): about $810

The written estimate, confirmed after we have checked the fiber, construction and condition, is the final price. Specialty treatments such as pet decontamination or stain removal are only added if you approve them. Full details are on the pricing page.

How much does it cost to clean a 9 by 12 oriental rug?

A 9×12 is about 108 square feet. At our published Oriental rug rate of $7.50 per square foot that comes to about $810. For comparison, a handmade wool rug of the same size is about $702 and a silk rug about $864.

Rugs are measured before the estimate is confirmed, and a 9×12 is often a little larger or smaller than its label, so the final figure can move slightly. You see the written estimate before any work begins.

Value and authenticity

Are old Persian rugs worth anything?

Many are, sometimes considerably more than people expect. Value depends on where and when the rug was made, its knot density, the materials (wool, silk or both), the quality of the design and colors, and above all its condition.

Condition is the part owners control. Two rugs of the same type can be worth very different amounts if one has been cleaned regularly and repaired early while the other has moth damage, worn edges and run colors. That is why we always suggest cleaning and repairing a good old rug rather than leaving it rolled in a garage. For an actual figure, for insurance, an estate or a sale, have the rug appraised by a specialist.

How can you tell if a Persian rug is authentic?

Start by turning a corner over. A few signs of a genuine hand-knotted rug:

• The back shows the pattern clearly, made up of individual knots, and small irregularities in the rows are normal.
• The fringe is the ends of the warp threads running through the rug, not a strip sewn or glued onto the ends.
• The fibers are natural (wool, silk, cotton), and the rug is usually flexible enough to fold back on itself.

Warning signs of a machine-made or tufted rug include a glued or canvas backing, perfectly uniform rows, and fringe that is attached separately. If you are unsure, a specialist can tell quickly from a few close-up photos of the back.

Home remedies to avoid

Does Dawn dish soap clean rugs?

On a synthetic rug, a few drops of mild dish soap in cool water can lift a fresh spot. On wool and silk, we would steer clear. Dish soap is designed for grease on dishes, not for protein fibers; it is hard to rinse out of a dense pile, and any residue left behind attracts dirt, so the spot comes back darker a few weeks later.

For a Persian or other handmade rug, blot a spill with a clean white cloth and plain cool water, working from the outside in, and leave anything more to a specialist.

What is the best thing to wash a rug with?

It depends on the fiber. For a handmade wool rug, a pH-neutral or slightly acidic, wool-safe rug shampoo in cold water, followed by a thorough rinse. For a synthetic rug, a mild, low-residue detergent works. For silk and viscose, only a specialist wash; both behave very differently when wet.

Whatever you use, two rules apply: test it first on a hidden corner, and rinse it out completely. Soap left in the pile is the most common reason a rug looks dirty again soon after cleaning.

Can I use peroxide and Dawn to clean my carpets?

Only cautiously, on light-colored synthetic carpet, and never on a Persian rug or any dyed wool. Hydrogen peroxide is a bleaching agent. On natural dyes it can lighten or strip the color and leave a pale patch that cannot be put back.

If you want to try it on a synthetic carpet, use a weak solution, test it on a hidden spot first, and rinse well afterwards. On a handmade rug, ask a specialist instead; the stain can usually be treated without risking the dye.

What happens when you mix Dawn dish soap and hydrogen peroxide?

They make a foaming stain remover. There is no dangerous reaction, which is why the combination is popular online, but the peroxide keeps its bleaching effect.

That is exactly why it can work on white or light synthetic fibers and why it can permanently fade colored wool, silk and natural dyes. The bubbles look like they are lifting the stain; on a dyed rug they may also be lifting the color.

What is a good homemade carpet cleaner for deep cleaning?

For synthetic carpet, warm water with a small amount of mild detergent and a splash of white vinegar, applied sparingly and rinsed out fully, handles most everyday soiling. Less is more; over-wetting and too much soap cause most of the problems.

Homemade mixtures cannot deep clean a handmade rug, though. The soil that actually wears a wool rug out sits down in the foundation, and getting it out takes thorough dusting followed by a full-immersion wash, which is not something a spray bottle can do.
