Merino wool is one of the higher quality wools, known for its exceptional softness. It’s made from Merino sheep, which have a very fine wool fiber that is ideal for the elastic and breathable knits used in many sporting and cold-weather garments. While Merino wool has the benefit of being largely wrinkle-, odor-, and stain-resistant, it still needs to be washed on occasion, especially when it has been soiled or heavily sweated on. Find out how to protect this fine natural fiber as you clean it through gentle washing, drying, and stain-removal.
Things You Should Know
- Use a wool-specific soap or detergent and warm water to clean merino wool.
- To hand-wash, soak the wool in soapy water for 3-5 minutes and rinse. If you prefer to use the washing machine, select the delicate cycle.
- Place the clean wool on a dry towel and roll it up to remove excess water. Then, lay the wool out flat to dry.
Steps
-
Get a wool-specific soap. Merino wool requires a very gentle washing liquid that will prevent bleeding of its color or damage to its fine fibers. Pick a shampoo, soap, or detergent that’s especially formulated for wool, like Woolite or Laundress Wool & Cashmere Shampoo.
- Never use fabric softeners or products with bleach in them on wool.
- In a pinch, you can use a mild soap with a neutral pH, like a clear, fragrance-free dishwashing fluid for sensitive skin.
-
Fill a basin with soap and warm water. Measure out your wool wash soap according to the guidelines on its packaging. Add it to a basin with enough warm water to cover your garments.
- The water should be between 30 and 40 degrees C (about 85-100 degrees F).
- If you have a really large Merino wool product, consider washing it in your bathtub or using a “soak” setting on your washing machine so that you have a big enough basin.

Soak your wool for 3-5 minutes. Completely submerge your Merino wool garment in the water, and let it soak for 3 to 5 minutes. Then, swish the water through the wool garment slowly and gently for about one minute.
- Don’t let your wool soak for more than a handful of minutes since doing so can warp the fibers.
-
Rinse with warm water. Rinse your wool several times with a gentle stream of warm water to get the detergent out. Keep rinsing it until the water runs mostly clear of suds.
- Make sure that your rinse water is the same temperature as the water in which you soaked your Merino wool.
-
Squeeze out excess water. Take the garment and squeeze it to get as much water out as possible. [1] X Research source
- Do not twist or wring your Merino wool to drain the water.

-
Wash smaller garments in the washing machine. It’s best to avoid washing larger garments, like sweaters or leggings in a washing machine. However, smaller Merino products, like hats, socks, or mittens, will be able to hold their shape better.
-
Wash with like colors and fabrics. Prevent any potential damage from your Merino wool bleeding by washing it with similarly colored garments, such as darks, brights, or lights. It’s also a good idea to wash it with clothing of similar weights or harder fabrics, like canvas or denim, for the sake of minimizing the pilling of the wool fibers. [2] X Research source
- To be completely safe, consider washing your Merino wool by itself. Keeping it separate from other laundry will preserve it and your other garments for longer.
-
Turn garments inside-out. To help keep your Merino wool from pilling or getting fuzzy on the outside, wash it inside-out. [3] X Research source
-
Use a wool-specific washing liquid. Merino wool necessitates a very gentle soap that will minimize bleeding or fiber-damage. Wash it with a shampoo or soap that’s especially formulated for wool or with a mild detergent that is free from bleach and fabric softeners.
-
Pick the right cycle. You want to select a gentle, delicate, or knit cycle so that the rotation of the machine will not damage the wool fibers or shape of your garment.
- Note: if you cannot control the speed and/or temperature of your washing machine, stick to washing your Merino wool by hand.
-
Set the right temperature. You want to wash your Merino wool at a consistent warm, low, or cold temperature. Warm (about 30 degrees C or 85 degrees F) is the usually the best bet, but be sure to check the care instructions of your garment’s tag to ensure you have the right temperature guidelines for your particular product. [4] X Research source
- Never change temperatures for your rinse cycle. To avoid shrinkage and felting, you need to keep the temperature of your entire wash cycle constant. Either do all warm water or all cold water, never a mix of the two.
- Never use hot water since high temperatures can seriously shrink your wool.
-
Remove from the machine immediately. As soon as the washing cycle is complete, take your Merino wool out of the machine and dry it according to the care instructions. Leaving it wet in a pile of other laundry will stretch and misshape the fibers.

-
Do not use a drying machine. Unless the washing instructions on your Merino wool product specifically indicate that you can use a dryer, do not tumble dry it. If the care instructions do permit it, be sure to use a gentle, low-heat setting.
-
Never wring your Merino wool. Twisting this fabric can seriously stretch it and leave your garment misshapen. Squeeze out excess water without twisting the wool. [5] X Research source
-
Roll it in a towel. Get out the excess moisture in your Merino wool by laying it in a dry towel and rolling it up. Gently squeeze the roll to remove as much of the remaining water as possible. [6] X Research source
-
Lay flat to dry. The best way to preserve the shape and texture of your garment is to reshape your Merino wool while it’s still damp and then let it dry on a flat surface. [7] X Research source
- You can use a flat drying rack for this. Some racks have a mesh surface that’s especially designed for garments that need to lay flat. You can also simply lay your garment on top of a dry towel on a flat surface, like a floor or bed.
- You don’t want to hang Merino wool on a hanger, line, or hook because the weight of the wet fibers can lead to sagging and stretched knits.
-
Keep it away from heat. Don’t leave drying Merino wool near a heat source, like a radiator, or in direct sunlight. You should dry your wool in the open air and away from heat to prevent shrinkage. [8] X Research source
-
If necessary, use a steam iron on a wool setting. Merino wool is not prone to wrinkling, but if you need to press it, wait until it’s completely dried. Then, use a steaming iron on a wool setting to press out the wrinkles.
- Don’t move the iron back and forth over the wool. Instead, lower the iron onto the fabric, press for a few seconds, and then lift it directly up. Repeat this process until you have the wrinkles out.
- If you have a delicate knit, cover the fabric with a clean, dampened dish towel before pressing it. This will protect the fibers.

-
Brush your Merino wool. Use a soft-bristled brush to gently remove any surface dirt, dust, or soil that could lead to a stain. Doing so will prevent any build-up that might dull the color and texture of your garment.
-
Spot clean stains immediately. Rinse the affected area with cold water and/or seltzer water to keep the stain from setting. Dab it out with a dry, soft, clean cloth.
- Avoid rubbing the stained area with your cloth since this will only encourage the stain to set into the fabric.
- For particularly stubborn stains, treat them with wool-specific soap. Dab a small amount of your mild wool detergent onto the affected area. Let it soak for a few minutes, and then rinse it with cold water. [9] X Research source
-
Use white spirit for grease stains. Remove any excess grease with a metal spoon. Then, soak a section of a clean, soft cloth with white spirit or mineral spirit. Gently blot the affected area until the grease comes up. [10] X Research source

She is well known in the region for outstanding customer service protocols — winning the 2017 Better Business Torch Award for Ethics & Integrity —and her energetic support of green cleaning practices.It absolutely can. Wool is a highly unpredictable and it can shrink all the way from XL to infant size if you don't handle it correctly. Check the tag for cleaning instructions. Some wool needs to be dry cleaned, while other wools do just fine with wool soap. Some wool garments can handle other washing methods. It really depends on the specific garment.

QuestionWhat if it has shrunk from the washing machine?Community AnswerFor any clothing item this is a great fix! Fill a sink or bathtub with lukewarm water and add maybe 2 tablespoons of conditioner into the water. It might not dissolve all the way but it's okay. Soak the item in this solution for 20 minutes. Then, take it out and start stretching it by hand, gently. Then let it dry (don't wash it again). Once it's dry, you can wash it how you normally should. The conditioner loosens up the fibers in the fabric so that you can pull them apart and stretch it to its normal size.
