How to Remove Black Walnut Stains from the Skin

Updated February 21, 2017

Black walnuts, which are harvested in the fall, require hulling as soon as possible to preserve the taste and colour of the nut. Handling black walnuts can stain your skin and your clothing. To avoid dealing with troublesome stains, wear old clothing and rubber gloves. If your hands do become stained, avoid touching your face or other exposed skin to prevent spreading the walnut juice. Remove black walnut stains using everyday household products. Black walnut stains will eventually wear out of the skin, even if you leave them alone or if your cleaning efforts are insufficient.

Cover your stained skin with lemon juice as soon as possible. Allowing the stain time to set into your skin may make it more difficult to remove. Sprinkle enough salt on the skin to lightly cover the stain.

Scrub the skin with a sponge while it is covered in lemon juice and salt. Rinse and wash the area with soap and water.

Repeat this procedure if the stain persists. Or, you may try covering the skin with another stain-lifting agent, such as white distilled vinegar or vegetable oil. If you choose a different substance as a cleaner, scrub the skin in the same manner as before.

Rinse the skin and wash it thoroughly with soapy water. Apply a lotion if the stain-lifting procedure irritated your skin.
