True or False: If oil from a toxic plant gets on the hands, washing with hot water and soap is effective.

Washing with hot water and soap is not effective for removing oil from toxic plants, such as poison ivy, poison oak, or poison sumac. These plants contain a substance called urushiol, which is an oily resin that can bind to the skin. Hot water can potentially open the pores and trap the oil even deeper in the skin, which can exacerbate the irritation and make it harder to remove.

Using soap with cold water is often recommended as it can help emulsify the oil and allow it to be washed away more effectively without the added complications of heat. Additionally, alcohol-based sanitizers are not suitable for this purpose, as they may not adequately dissolve the oil. Therefore, acknowledging that hot water and soap are not effective in this case leads to the conclusion that the statement is false.
