Black walnuts are round like a basketball and about two inches thick. Black walnuts taste delicious when used in baking various breads and cookies. Black walnuts actually contain a juice that can stain your fingers and clothing. If you are planning on picking or working with black walnuts, you will need to know how to remove these stains. Soap is not enough to get black walnut stains off.

Black Walnut Stains on Your Hands

Pour lemon juice on your hands, and rub them together for a few minutes. The acid in the lemon juice will get rid of black walnut stains.

Rinse your hands under the faucet with some warm water.

Give your hands a final wash with some dish detergent and water; otherwise your hands will be sticky from the lemon juice.

Black Walnut Stains on Your Clothes

Run cold water over the black walnut-stained clothing.

Squeeze two to three tsp. of dish detergent directly on the walnut stain.

Add four drops of vinegar to the dish detergent, and rub the two ingredients into the stain.

Wrap a paper towel around the stain, and wait 5 to 10 minutes before removing it.

Rinse the clothing piece out under a faucet of running water. Repeat until you have completely removed the stain.

Black Walnut

The black walnut grows well in a variety of conditions but performs best in open areas where the sun shines brightly throughout the day. During periods of drought, your black walnut tree may drop its leaves. The foliage of the tree typically develops into a rounded shape that spreads 60 to 80 feet. Plants that are suffering from juglone poisoning show stunted growth, wilting and yellowed leaves before eventually dying. The fruit of the black walnut tree has a hard, round casing that can create a hazard around the tree. Black walnuts are susceptible to minor pests, including tent caterpillars, scale insects, mites and webworm larvae.


Wear gloves when picking black walnuts so that your hands don't become stained again.


Do not use bleach to remove the walnut stain unless the fabric you are working with is white. Do not allow your fabric to become dry until you have completely removed the stain.
