Wash knitted blankets by hand in cool water with gentle detergent, never in a machine

Hand washing is the safest method for most knitted blankets because the agitation and heat of a washing machine can felt the yarn, stretch the fabric, or break delicate stitches. Fill a basin or sink with cool water (60 to 70 degrees Fahrenheit), add a small amount of wool-specific detergent or mild dish soap, and submerge the blanket. Let it soak for 10 to 15 minutes, then gently squeeze the soapy water through the fabric with your hands. Do not wring, twist, or scrub—the motion that cleans regular laundry will damage knit structure.

Rinse the blanket in cool water at least twice, or until the water runs clear and no soap remains. Squeeze gently each time. If your tap water is hard or heavily chlorinated, a final rinse in distilled water helps preserve the yarn's softness and color. The entire wash takes about 30 minutes from start to finish.

Key Takeaways

  • Hand wash knitted blankets in cool water with wool-specific detergent; machine washing risks felting and stretching the yarn.
  • Soak the blanket for 10 to 15 minutes, then gently squeeze soapy water through without wringing or twisting.
  • Rinse at least twice in cool water until no soap remains, squeezing gently each time.
  • Dry flat on a towel or drying rack, never in a dryer or hung on a line, to prevent stretching and distortion.
  • Check the yarn fiber content before washing—acrylic and cotton have different care needs than wool or wool blends.

Check the yarn fiber before you wash

The fiber content of your blanket determines how much care it needs. Wool and wool blends are prone to felting if exposed to heat or agitation, so they require the gentlest handling. Acrylic yarn is more durable and forgiving; it can tolerate slightly warmer water and a bit more agitation, though hand washing is still safer than machine washing. Cotton and linen blends are also sturdy but can lose shape if wrung out aggressively.

Look for a yarn label or tag attached to the blanket, or check the pattern if you knitted it yourself. If no label exists, test a small, hidden corner by dampening it with cool water and a drop of detergent. If the fibers begin to mat or felt within a few minutes, treat the entire blanket as wool and use the gentlest method. If the fibers stay separate and springy, you can use slightly warmer water (up to 80 degrees) and a bit more gentle agitation.

Prepare your washing space and gather supplies

Use a clean sink, bathtub, or large basin that is big enough for the blanket to move freely without bunching. Avoid surfaces with rough edges or metal fixtures that can snag yarn. Fill the basin with cool water before adding the blanket—this prevents the shock of sudden temperature change and gives you a chance to dissolve the detergent evenly.

Gather these supplies: wool-specific detergent (brands like Eucalan, Soak, or The Laundress are common choices), or a mild dish soap like Dawn if you do not have wool detergent. Avoid regular laundry detergent, which is too harsh and can strip natural oils from wool. You will also need clean towels for drying and a flat surface like a drying rack, mesh screen, or clean towel laid on a table or floor.

Soak and gently clean the blanket

Add one to two teaspoons of wool detergent to your basin of cool water and stir gently to dissolve. The water should feel slippery but not soapy—you want just enough detergent to clean, not so much that rinsing becomes difficult. Submerge the blanket slowly, pushing it down gently so water fills all the folds and pockets. Let it soak for 10 to 15 minutes without moving it. This soak time allows the detergent to loosen dirt and oils without requiring scrubbing.

After soaking, gently squeeze the soapy water through the fabric by pressing your hands together with the blanket between them. Work your way across the entire blanket, paying extra attention to areas that touch skin (edges, corners) or collect dust. Do not lift and drop the blanket, wring it, or rub one section against another. If the blanket is very large or heavily soiled, you can drain the soapy water and repeat the soak and squeeze process once more with fresh soapy water.

Rinse thoroughly until water runs clear

Drain the soapy water and refill the basin with cool, clean water. Submerge the blanket again and gently squeeze the rinse water through the fabric, just as you did with the soap. Drain and repeat at least one more time. The blanket is fully rinsed when the water you squeeze out is clear and has no soapy smell or feel. Leftover soap residue will make the yarn stiff and dull, so take time with this step—it usually requires two to four rinses depending on how much detergent you used.

If your tap water is hard (mineral-rich) or smells strongly of chlorine, a final rinse in distilled water or filtered water will improve the blanket's softness and color. This step is optional but worth doing for blankets you plan to keep for years.

Dry the blanket flat to prevent stretching

Never put a wet knitted blanket in a dryer or hang it on a clothesline—the weight of the water will stretch the stitches permanently, and heat will damage the yarn. Instead, lay the blanket flat to dry. Spread a clean, dry towel on a table, bed, or floor, then lay the damp blanket on top. Smooth it gently into shape, making sure corners are square and edges are straight. If your blanket is very large, you can use a mesh drying rack or a clean window screen laid over a bathtub or table.

Allow the blanket to air dry completely, which usually takes 24 to 48 hours depending on humidity and yarn thickness. Turn it over halfway through drying so both sides dry evenly. Once fully dry, fold and store in a cool, dry place. If you notice the blanket has stretched or lost its shape during drying, you can gently reshape it while still slightly damp and let it dry again in the correct position.

Handle stains and problem areas

For small stains, spot-clean before the full wash. Mix a small amount of wool detergent with cool water to make a paste, explore it directly to the stain, and let it sit for 5 to 10 minutes. Gently rub the area with your fingers or a soft cloth, then rinse with cool water until the stain and soap are gone. This approach works well for food, dirt, or minor discoloration without requiring a full wash.

For stubborn stains like wine or ink, soak the stained area in cool water with detergent for 20 to 30 minutes before attempting to rub. If the stain does not lift after one attempt, repeat the soak rather than scrubbing harder—aggressive rubbing damages the yarn structure. Some stains may not come out completely, especially on lighter-colored yarn, and that is normal wear for a frequently used blanket.

Frequently Asked Questions

Can I use a washing machine on the delicate cycle?

A delicate cycle is gentler than regular wash, but the drum still agitates the blanket and can cause felting, especially with wool. Hand washing is safer. If you must use a machine, use a mesh laundry bag, cold water, wool detergent, and the gentlest cycle available—but hand washing remains the best choice for preserving the blanket's structure and appearance.

How often should I wash a knitted blanket?

Wash a blanket every few months if it is used regularly, or once or twice a year if it is decorative or rarely used. Frequent washing wears yarn faster, so spot-clean stains between full washes when possible. Airing the blanket outdoors on a breezy day removes dust and odors without requiring a wash.

What if the blanket smells musty after drying?

Musty smells usually mean the blanket did not dry completely or was stored in a damp space. Lay it flat in a warm, dry room with good air circulation and let it dry fully. Once dry, store it in a breathable cotton bag or pillowcase rather than plastic, which traps moisture. If the smell persists, soak the blanket in cool water with a small amount of white vinegar (one tablespoon per gallon) for 15 minutes, then rinse and dry again.

Can I use fabric softener on a knitted blanket?

No—fabric softener coats the yarn and makes it stiff and slippery over time. Wool detergent and gentle handling are enough to keep the blanket soft. If the blanket feels rough after washing, the problem is usually leftover soap residue, so rinse more thoroughly next time.

What should I do if the blanket shrinks or stretches?

Shrinking usually happens from hot water or heat in the dryer and cannot be reversed. Stretching can sometimes be corrected by reshaping the damp blanket to its original dimensions and drying it flat in the correct position. Blocking—pinning the blanket to the correct shape while damp—works for some fibers but is time-consuming. Prevention through cool water and flat drying is far easier than repair.
