How to clean a rug

Vacuuming is the most frequent cleaning routine, once or twice a week is enough in a typical living room. What goes beyond that depends on the fibre.

Wool rugs need a professional wet cleaning in running water every three to five years. Without this deep-cleaning appointment, the lanolin slowly felts together with house dust and the pile loses its dirt-repellent effect.

Silk rugs are not cleaned wet, but refreshed dry by a professional every one to two years. Water leaves rings that no longer disappear.

Cotton rugs and flat-woven kilims tolerate more frequent washing, small pieces even go into the machine.

Jute and sisal cannot take water. They are cared for dry, a professional dry cleaning every two years is enough.

Polypropylene and other synthetic rugs are the most robust. They tolerate water, mild soap, even regular damp wiping. A thorough wash every one to two years keeps them fresh.

You do not need specialist equipment. Four tools cover 90 percent of all care steps.

A vacuum cleaner with a smooth nozzle, without a rotating brush. Rotating brushes pull wool fibres out of the knot and accelerate wear. On polypropylene or other synthetic fibres they are permissible, but even there not needed.

A soft brush or hand brush, for lifting the pile after vacuuming and for dry cleaning with starch or baking powder.

White absorbent cloths, ideally cotton or undyed microfibre. Never coloured cloths, because dye from the cloth can transfer into the rug.

Mild wool detergent or colourless soft soap. A single drop per litre of water is enough. Never heavy-duty detergent, never washing-up liquid with bleach or citrus extracts, never glass cleaner.

Optional: baking powder or cornstarch for dry stain treatment, white vinegar for wool rugs (diluted, one tablespoon per half-litre), salt as a first-response measure for wine.

Dry cleaning is the gentlest option, and suitable for any delicate fibre.

Step 1: Vacuum the rug thoroughly, in the direction of the pile. You can identify the pile direction by running your flat hand across the rug. Wherever it feels smooth is the lay of the pile.

Step 2: Apply a dry cleaning agent. For wool, cornstarch or baking powder, sprinkled evenly onto the pile, about two tablespoons per square metre. For silk, only a light veil of fine cornstarch. For jute and sisal, coarse sawdust mixed with a few drops of cleaning alcohol, a traditional method from the Hamburg Speicherstadt.

Step 3: Work it gently into the pile with a soft brush, against the lay of the pile, so that the powder reaches the base of the knots.

Step 4: Let it sit for 30 to 60 minutes. The powder pulls grease, skin flakes and fine dirt particles out of the fibre.

Step 5: Vacuum thoroughly, several times in different directions. One bag is not enough for a living room, plan on two or three.

The result: a noticeably fresher look, without water ever touching the fibre.

When the fibre tolerates water, the damp method is more thorough. Four fibres are suitable: polypropylene, polyester, modern wool rugs with explicit machine-wash approval, and cotton kilims.

Step 1: Vacuum, as above. Loose dirt must be gone before water comes in.

Step 2: Mix a solution of lukewarm water (no more than 30 degrees for wool, up to 40 degrees for polypropylene) and a drop of wool detergent per litre.

Step 3: Dip a soft cloth or sponge, wring it out well, run it over the rug in the direction of the pile. Never soak the rug. The fibre should be damp, not dripping wet.

Step 4: Follow up with a second cloth and clear water to remove soap residues. Residues bind dirt later.

Step 5: Drying. With polypropylene, a hairdryer on the cold setting or air drying is usually enough. With wool, dry flat in the air only, never hung up, never in the sun, never with a heat source. A soaked wool piece takes two to three days to dry.

For very small synthetic rugs with machine-wash approval, a gentle wash at 30 degrees in the washing machine is possible, on the wool cycle without spinning, then dried flat.

Wool: lanolin protects the fibre, so no heavy-duty detergent and no shampoo. Vacuum with a smooth nozzle, blot stains with cold water, deep wash every three to five years by a professional with a pH-neutral cleaner.

Silk: no water, no self-attempts with stains. Vacuum only on the lowest setting with a soft nozzle. Deep care exclusively by specialised cleaners who know the dry process.

Cotton: robust in modern quality. Machine wash in small format on the gentle cycle, larger pieces by hand or professionally. Have old cotton rugs with brittle warp threads examined by a specialist before any treatment.

Jute and sisal: no water at all. Vacuum, dry brushing in the lay of the pile, professional dry cleaning. In damp rooms mould can form, so do not lay them in the bathroom or in a damp basement.

Polypropylene: the most uncomplicated. Tolerates water, mild soap, even shampoo. What it does not tolerate is heat. Hot-air dryers, steam cleaners above 60 degrees or irons melt the fibre. More on this on the page Polypropylene rug.

For every stain the rule is: acting quickly matters more than the perfect product. Blot, never rub. From the outside in, always with a fresh side of the cloth. Cold water first, never warm. Specialist cleaners only when clear water is not enough.

For typical household stains we have our own deep-dive articles:

Coffee: blot quickly, cold water, neutralise tannins with vinegar on wool. Details under Removing coffee stains from a rug.

Red wine: mineral water or salt at once, stubborn stains with baking powder paste. Details under Removing red wine stains from a rug.

Blood: cold water only, heat fixes permanently. Details under Removing blood from a rug.

Unknown stains: first pick up dry, then blot with cold water and a drop of wool detergent. If two rounds bring no visible improvement, stop the self-attempt and call a cleaner.

Four situations are not a DIY job.

Size: a rug larger than 200 by 300 centimetres can no longer be properly washed through at home. The water does not reach the backing, residues stay in and attract dirt. Here a professional wet wash at a Hamburg rug wash is the right method.

Fibre: anything in silk, all antiques, all pieces with brittle warp threads, all naturally-dyed rugs. Here home remedies risk more damage than they repair. A pH-neutral professional wash costs 80 to 200 euros for a medium-sized piece and protects the fibre and the colour.

Value: a hand-knotted rug from Persia, Anatolia or Nepal with a replacement value above 1,500 euros belongs in professional care. The investment in a proper wash every three to five years is a fraction of a restoration job.

Contamination: animal urine deep in the backing, mould, parasites like giardia or moths. Here you need specialised active ingredients and procedures that a household cannot match. Fire and water damage also belong in professional hands.

With every provider, ask specifically about: experience with oriental rugs, pH-neutral cleaners, and flat drying. Anyone who does not clearly confirm these three points is not the right provider.
