Wool is a natural fiber that reacts to heat, agitation, and harsh chemicals. That’s why some slippers shrink or harden after washing.
But if you treat wool gently, it will remain soft, breathable, and durable. That’s one of the reasons people choose it over synthetics.
Step-by-Step: How to Wash Wool Slippers
1. Check the Care Label
Not all wool slippers are made the same. At Sheep Sisters, our slippers are crafted from 100% European merino wool and can be safely washed on a gentle wool cycle. Always check your care label before washing.
2. Pick the Right Detergent
Use a mild wool detergent containing lanoline (sheep's fat) or baby shampoo. Avoid bleach, fabric softener, or regular laundry powder, as these can damage the fibers.
3. Washing Methods
Option A: Hand Wash (Safest)
-
Fill a basin with cold or lukewarm water.
-
Add a few drops of wool detergent.
-
Submerge slippers and gently squeeze (don’t rub or wring).
-
Rinse with clean water until soap is gone.
Option B: Machine Wash
-
Select the wool or delicate cycle.
-
Temperature: cold or max. 30°C (86°F).
-
Spin speed: low. Best below 800
-
Place slippers in a mesh laundry bag for protection.
4. Drying Your Wool Slippers
-
Never use a dryer — heat shrinks wool.
-
Press gently with a towel to remove water.
-
Reshape slippers with your hands.
-
Lay flat to air dry, away from sunlight or radiators.
- Brush gently to fluff it
How Often Should You Wash Wool Slippers?
Unlike synthetic materials, wool doesn’t need frequent washing. Most slippers only need a proper wash every 6–12 months. In between, you can simply:
-
Air them out by a window
-
Spot clean stains with a damp cloth
- Brush them. Regular hairbrush will be ok
Extra Tips to Keep Wool Slippers Fresh
-
Alternate pairs: Give your slippers time to air out between wears.
-
Avoid overwashing: The less agitation, the longer they last.
-
Use natural freshening tricks: A sprinkle of baking soda inside overnight works wonders.
Final Thoughts
So, can you wash wool slippers without shrinking them?
Yes — as long as you wash gently and skip the heat.
With the right care, your slippers will stay cozy, but I'm sorry... they won't last for many, many years. You will love them and they will carry you everyday, so they will wear out. Only plastic lasts forever and you won't find it in our slippers.
At Sheep Sisters, our 100% merino wool slippers are machine-washable, breathable, and crafted to stand the test of time.
