Lambskin jackets, also known as sheepskin coats, are made from the hides of sheep. Lambskin jackets can come in a wide array of colours; however, tan, brown and black are the most common hues that are available. The shearling material is soft to the touch and is similar to suede by the stroke and by sight. The leather material is delicate and can be challenging to clean and care for. The shearling material can also tear easily, which is why most manufacturers recommend "dry clean only." With proper washing, anyone can clean a lambskin jacket at home.
Rinse a washcloth under water. Wring the washcloth out slightly. Open the jacket up to test a small, inconspicuous area for colour fastness and to prevent damaging the entire item from washing. Dab a spot with the washcloth. Apply a drop of soap to the wet area. Massage the soap into the coat. Gently rinse the soap out of the jacket by blotting the spot with the washcloth. Allow the spot to dry thoroughly. Check the spot for colour fastness before washing. If the spot appears different in appearance then you will need to have the jacket dry cleaned. Use a mild dish soap that is perfume, oil and dye free. Alternately, use baby shampoo.
Fill a bathtub up with lukewarm water. Dump 4 to 5 tbsp of the dish soap into the tub and swish the water around with your hand.
Gently submerge the lambskin jacket into the water. Push the coat down to insure that it is completely soaked. Allow the lambskin jacket to soak for half an hour.
Rub the palm of your hands gently back and forth over the outside of the jacket. Use your fingertips to rub stitchings, cuffs and the area around buttons.
Gently rub the palm of your hand inside the jacket and arm holes.
Remove the drain plug from the bathtub. Gently use the palm of your hands to squeeze out water from the jacket. Pick the jacket up and gently wring out any remaining water.
Rinse the lambskin coat for up to 10 minutes under cold water. Thoroughly rinse the inside and outside under the water. Turn the water off and gently wring out the jacket.
Place the jacket flat onto a large towel. Stuff the jacket arms with several dish towels for reshaping the shearling. Button the front of the jacket up and stuff a few large towels inside.
Place a fan in front of the lambskin jacket and turn it onto the lowest setting. Gently rub your hands over the front of the coat and lightly tug on the bottom and arms to remove wrinkles.
Flip the coat over when the front is completely dry so that the back can dry under the fan. Remove towels when the jacket is completely dry.
Have the lambskin jacket dry cleaned if it has fur or other materials sewn on it.
