Pet Urine on Area Rugs: How to Clean Wool and Jute Safely

An area rug is not the same as wall-to-wall carpet. It is often made of natural fiber, it may have dyes that run, and it usually sits on a hard floor, so urine can pass straight through to the backing and the floor below. Wool and jute are the two rug materials people most often damage while trying to clean them. This guide covers what to do with a fresh accident, an old smell, and what not to use on each fiber.

It follows the stain guidance of the British carpet maker Cormar for wool, the care guide of the natural fiber rug maker Sisal Rugs Direct for jute, and Humane World for Animals on pet stains and odors. Your rug’s own care label comes first: it may say “dry clean only” or “spot clean only”, and that changes what you can do at home.

First: check the label and test

Find the fiber. The label usually says wool, jute, sisal, cotton, viscose or a synthetic such as polypropylene. Synthetics are the easiest; viscose (also sold as “art silk” or bamboo silk) is one of the hardest, since it can be damaged by water.
Test every product on a hidden spot. Cormar advises testing treatments on an inconspicuous part of the carpet for possible color change before you treat the stain. On a rug, the underside of a corner works.
Check for dye bleed. Press a damp white cloth on a dark and a red area of the rug for a minute. If color transfers to the cloth, the dyes can run, so keep moisture to a minimum and think about a professional rug cleaner.

Fresh accident on any rug: the first five minutes

Lift the corner. Put a towel or a plastic bag under the wet area so urine does not soak through into the rug pad or the floor.
Blot, do not rub. Press with white paper towels or a white cloth until no more moisture comes up. Cormar says not to rub the pile during stain removal, and to work inwards from the edge of the stain so it does not spread.
Blot from the back too. Turn the corner over and blot the underside, since urine often reaches the backing first on a thin rug.
Treat by fiber, as described below.
Dry it fast. Prop the area up so air can reach both sides and point a fan at it.

Wool rugs

Wool is absorbent and takes dye well, which is why a urine spot on a wool rug can leave both a smell and a color change. It also tolerates gentle cleaning well when you do not over-wet it.

Blot up everything you can, as above.
Apply the product to a cloth, not the rug. Cormar’s wool guidance is to put a pet stain remover approved by WoolSafe (an independent body that tests products for use on wool) on a damp cloth and blot the stain, rather than pouring or spraying it on.
Rinse lightly. Cormar says to rinse by applying a small amount of clear, tepid water with a clean cloth or sponge, then blot dry. Small amounts, repeated, are safer than one large soak.
Let it dry between steps. Cormar advises making sure the carpet is dry before moving on to the next step of a treatment.
For odor that stays, use an enzymatic cleaner whose label says it is safe for wool, and test it first. Humane World for Animals recommends enzymatic cleaners for pet urine, because they break down pet waste odors.

Avoid on wool: hot water, steam, chlorine bleach and strong alkaline cleaners, and hard scrubbing, which can felt or fuzz the pile. Do not dry it in direct heat.

Jute rugs

Jute is a plant fiber, and water is its main enemy. Sisal Rugs Direct explains that jute is highly absorbent, so excess moisture can cause warping, shrinkage, discoloration or mold if it is not dried quickly. Many brown water marks on jute rugs come from the cleaning, not the accident.

Blot right away and firmly, with white cloth or paper towels, working from the outside of the spot inward. Sisal Rugs Direct says to keep blotting until no more moisture transfers to the towel.
Keep any liquid to a minimum. If you use a cleaner, use one labeled safe for natural fibers, put it on a cloth and dab, then blot dry. Do not spray or pour it straight on the rug.
Dry it immediately. Sisal Rugs Direct recommends drying with a fan or a hair dryer, so moisture does not sit in the fibers.
Soaked through? If the urine went deep into the weave or the backing, a home fix is unlikely to remove the smell. A rug cleaner who works with natural fibers is the realistic option, or replacing a low-cost rug.

Avoid on jute: Sisal Rugs Direct lists soaking, steam cleaning and shampooing as things to avoid, and says steam cleaning can cause shrinkage, discoloration and structural damage. The same applies to sisal and seagrass rugs.

Cotton and synthetic rugs

Small cotton rugs are often machine washable. Check the label, rinse the spot in cold water, treat it with an enzyme product and wash as directed.
Polypropylene, nylon and polyester rugs handle water well. Blot, treat with an enzymatic cleaner, rinse and dry. Our carpet urine guide covers this step by step.
Viscose, rayon and silk can be damaged by water and stain easily. Blot only and call a professional.

What not to use on any rug

Ammonia and vinegar as an odor fix. Humane World for Animals advises avoiding them for pet urine, because strong chemical smells may encourage your pet to mark the same spot again.
Steam or hot water on urine, which can make the smell harder to remove and can shrink natural fibers.
Bleach, which can strip color from dyed rugs. Never mix it with ammonia or acids such as vinegar.
Scented sprays alone. They cover the smell for a day; the urine is still in the rug.

For a side-by-side look at the common home remedies, see vinegar, baking soda or enzyme cleaner.

Old smells and hidden spots

If a rug smells but you cannot see a stain, check it in the dark with a UV black light, where dried urine often glows. Check the rug pad and the floor under it too: urine that went through can stay in a pad or in hardwood long after the rug is clean. See how to find pet urine with a black light and, for wood under the rug, how to clean pet urine from hardwood floors.

When to call a rug cleaner

The rug is antique, handmade, valuable or labeled dry clean only.
The dyes ran in your test.
Urine soaked through a wool or jute rug, or the smell came back after two home treatments.
The rug is viscose or silk.

For wool, Cormar points to WoolSafe, which lists cleaners and products approved for wool.

Keep cleanup supplies ready

Our Pet Cleanup Kit has gloves, an enzyme odor product, an absorbent powder and a UV black light in one pouch, so you can blot and treat a rug accident before it dries. Check the label to confirm it suits your rug’s fiber, and test it on a hidden spot first.

Frequently asked questions

Can I use an enzyme cleaner on a wool rug?

Choose one whose label says it is safe for wool, apply it to a cloth rather than soaking the rug, and test it on a hidden spot first. Cormar’s guidance for wool is to use a WoolSafe approved pet stain remover.

Why did my jute rug turn brown after cleaning?

Usually because it got too wet. Sisal Rugs Direct notes that excess moisture can discolor jute if it does not dry quickly. Use as little liquid as possible and dry the area right away with a fan or hair dryer.

Do I need to clean the rug pad too?

If urine went through the rug, yes. A pad holds urine like a sponge and will keep the smell going. Many pads are cheaper to replace than to clean.

Can I put a wool rug in the washing machine?

Only if the label says so. Most wool area rugs are not machine washable; spot clean them or use a professional rug cleaner.
