2. Change Your Clothing
The oily sap from the poison oak will also adhere to your clothes. Touching the fabric can spread the sap and further aggravate the skin. As soon as possible after coming into contact with poison oak, change your clothing. Make sure that any contaminated items of clothing are thoroughly washed to remove any traces of the oily sap. The same applies to any gear you may have, like backpacks, sports equipment and tools like spades, shears, loppers, etc. that may have come into contact with the poison oak. Wash everything down with water and soap to prevent further irritation.
