In short

To clean a wool area rug at home, vacuum it gently on both sides, blot spills with cool water and a tiny amount of wool detergent, and keep the rug as dry as you can. Skip carpet shampoo, hot water, bleach and rental machines. Wool that is soaked at home can brown, shrink or bleed dye.

Worth remembering

  • Vacuum with suction only, or with the beater bar at its highest setting, and go slowly.
  • Blot spills with cool water and a white cloth. Never rub and never soak.
  • Skip carpet shampoo, hot water, bleach and rental machines.
  • Stop and call a cleaner if a spill spreads, the dye runs or the rug gets soaked.

Routine care that makes cleaning rare

Most of what keeps a wool rug in good shape is routine. Vacuum it weekly and slowly, with suction alone or with the beater bar at its highest position, because a spinning bar pulls yarn out of the foundation and shortens the life of the rug. Turn the rug over and vacuum the back every month or two to loosen the grit under the pile. Use the hose attachment on fringe.

Turn the rug 180 degrees every six months so wear and sunlight even out, and set it on a breathable pad. Keep it out of all day direct sun, which fades wool.

Spot cleaning, step by step

Test everything first. Dab a hidden corner, wait until it dries and check the cloth for color. If color comes off, stop and call a cleaner. Otherwise work in this order.

  • Blot the spill at once with a clean white cloth, pressing straight down and working from the outside of the spill inward.
  • Lift off anything solid with a spoon or a dull knife.
  • Dampen a second white cloth with cool water and a very small amount of detergent made for wool, then dab the mark.
  • Rinse by dabbing with a cloth dampened in plain cool water until no suds show.
  • Press dry towels onto the spot, then point a fan across the rug.

Why not dish soap or carpet shampoo

Most carpet shampoos are alkaline, which dulls and weakens wool. Plain dish soap tends to leave residue that draws soil back into the pile. A detergent sold for wool, used in tiny amounts, is the safer choice. Keep the water to a minimum. A soaked wool rug takes a long time to dry, and a slow dry can pull brown marks and dye up from the foundation.

What not to do at home

  • Do not rent a machine that floods the rug with hot water. It can shrink and bleed wool.
  • Do not use bleach, oxygen boosters or ammonia, and never mix cleaning products.
  • Do not drape a wet wool rug over a rail or leave it rolled. Dry it flat with air moving around it.
  • Do not use a hair dryer, a heater or direct sun to hurry the drying.
  • Do not beat the rug hard or scrub the pile.

When home care stops

Home care handles surface soil and fresh spills. It does not reach grit packed into the base of the rug or a smell that has settled in. A full cleaning is better left to a cleaner who matches the method to that rug and explains the limits first. Wool rugs are cleaned in place, and one that calls for a full immersion wash is named as such. Stop at home and call if a spill spreads, if color shows on your cloth or if the rug has been soaked.

Questions, answered

Is it safe to put a wool rug outside to air it?

Briefly, yes, in the shade on a dry day. Lay it flat or drape it over a wide, clean support. Direct sun fades the color, and evening air can leave the rug damp. A good airing freshens a rug but does not replace a cleaning.

Can I use a rental carpet cleaner on a wool rug?

Better not. Rental machines usually apply hot water and leave a lot of moisture behind, which can shrink, brown or bleed wool, and they are hard to rinse well. A low moisture cleaning that begins with a dye test is the safer route.
