Poison Ivy is obviously to be avoided at all costs. But sometimes, it just happens that you come in contact with it. I asked my mother for the best strategy if one thinks they have had poison ivy touch their skin.
Her answer was to wash the affected are with laundry detergent or any ‘harsh’ soap. Not sure if that is an effective solution but she has 88 years of experience with poison ivy so no downside to trying if you have come in contact.
