TL;DR
Wash throw blankets and removable pillow covers every two to four weeks if they are in daily use, and read the care tag before every first wash -- fibre content decides everything. The most common mistakes are heat and agitation: both shrink wool, both pill synthetics, and both are avoidable.
What these items pick up
Throws and covers do more work than their appearance suggests. They live on the seating in the busiest room in the house, and they collect skin oil, hair products, food crumbs, pet hair, and whatever was on hands and clothing.
They also absorb odor. Fabric holds airborne cooking smells and smoke far more readily than hard surfaces do, which is why a room can be spotless and still smell of last night's dinner if the soft items have not been laundered in a while.
Unlike bedding, throws rarely go on a fixed schedule, so they drift for months. That is the actual problem this article solves: not a difficult technique, just a missing cadence.
How often should you wash a throw blanket?
Every two to four weeks for a throw in daily use, every two to three months for one that is mostly decorative, and immediately after any spill or illness. Pillow covers that people rest their heads on follow the shorter interval; purely ornamental ones can go on the longer one.
Read the care tag, every time
Fibre content decides the method, and the tag is the only reliable source.
| Fibre | Wash | Dry |
|---|---|---|
| Cotton | Warm or cool, normal cycle | Tumble low; expect some shrinkage on the first wash |
| Linen | Cool, gentle | Line dry or tumble low; it softens with use |
| Polyester and microfibre | Cool, gentle | Low heat only -- high heat melts and pills the fibre |
| Fleece | Cool, gentle, no softener | Low or no heat; softener destroys the loft |
| Acrylic | Cool, gentle | Low heat; it pills easily under agitation |
| Wool and cashmere | Cool, hand wash or wool cycle | Never a tumble dryer; dry flat |
| Faux fur | Cool, gentle, in a wash bag | Air dry only; heat mats the pile |
| Chenille | Cool, gentle | Air dry; heat crushes the pile |
| Knitted or chunky knit | Hand wash or wool cycle | Dry flat, reshaped, never hung |
Two rules cover most of the failures. Wool and cashmere felt permanently under heat plus agitation, and the damage is irreversible -- the method that avoids it is in how to wash wool and cashmere at home. And synthetic pile fabrics such as fleece, faux fur, and chenille are damaged by dryer heat, which mats or melts the surface.

When there is no tag
Cut tags are common on throws, since people remove the scratchy label from something that touches skin.
Default to the gentlest option: cool water, gentle cycle, mild detergent, and air dry. That will not damage anything, and the worst outcome is that a robust cotton throw comes out slightly less clean than it could have.
Test for colorfastness first if the item is dark or heavily patterned. Dampen a white cloth, press it against an inside seam for a minute, and check for dye transfer. If colour comes off, wash it alone.
Pillow covers: take them off first
A removable cover is designed to be washed separately from the insert, and washing the whole pillow when only the cover is soiled is how inserts get ruined.
Unzip and remove the cover. Zip the zipper closed before washing -- an open zipper snags other fabric and can tear a seam.
Turn the cover inside out if it has any embellishment, embroidery, or a printed face. That protects the decorative surface from abrasion in the drum.
Some covers should never go in a machine at all, generally because of a backing, a trim, or a fibre that will not survive agitation -- the list is in the cushion covers you should never machine wash.
The inserts themselves and any pillow without a removable cover follow a different routine, described in how to clean decorative throw pillows.
Washing without wrecking anything
Use less detergent than the cap suggests. Excess detergent does not rinse out fully and leaves a residue that stiffens fabric and holds odor. This is the most common cause of a freshly washed throw that still feels off.
Skip fabric softener on fleece, microfibre, and anything with a pile. It coats the fibres and flattens the loft, which is the opposite of what makes those fabrics pleasant.
Do not overload the drum. Bulky items need room to move for the water and detergent to reach the fibre. One large throw is a full load.
Use a wash bag for anything delicate, fringed, or trimmed. Fringe tangles around the agitator and around other items.
Remove pet hair first. A lint roller or a quick tumble on air-only before washing gets far more hair out than the wash cycle will. Wet hair mats into the fabric.
Drying is where most damage happens
Low heat or no heat, for almost everything on the list above.
Air drying is the safe default and it is faster than people expect for a single throw. Lay knits and wool flat and reshape them; hanging a wet knit stretches it permanently out of shape. The general trade-offs are in line drying versus machine drying.
If you use a dryer, take the item out slightly early and finish it in the air. Overdrying is what causes static, pilling, and a coarse hand on synthetics.
Never put anything away damp. Fabric stored with residual moisture develops a musty smell quickly, and folded bulk fabric dries very slowly.
FAQ
How often should you wash throw blankets?
Every two to four weeks for one in daily use on a sofa or bed, and every two to three months for a mainly decorative throw. Wash immediately after any spill or illness, and more often in a home with pets.
Can you put a throw blanket in the dryer?
Most can go in on low heat, but wool, cashmere, faux fur, chenille, and many knits should not. Heat felts wool permanently and mats or melts synthetic pile. When in doubt, air dry -- it is never the wrong choice.
How do you wash throw pillow covers?
Remove the cover from the insert, close the zipper, turn it inside out if it has any decorative face, and wash cool on a gentle cycle with similar items. Air dry or tumble on low. Some covers with backings or trims should not be machine washed at all.
What if a blanket has no care tag?
Default to cool water, a gentle cycle, mild detergent, and air drying. That combination will not damage any common fibre. Test dark or patterned items for colour transfer by pressing a damp white cloth against an inside seam first.
Why does my fleece blanket feel rough after washing?
Usually fabric softener or dryer heat. Softener coats and flattens the pile, and high heat melts the fibre tips into a stiffer surface. Wash cool without softener and dry on low or air only, and the texture generally improves over a few cycles.
How do you get pet hair out of a blanket?
Remove as much as you can before washing, with a lint roller or a tumble on the air-only setting, because wet hair mats into fabric rather than releasing. Wash the item alone so the hair does not transfer, and clean the lint filter afterward.
