No, a very common misconception is that you should use bleach on
poison ivy rash. Using bleach for poison ivy may seem to be a quick
fix to removing the rash-causing oil, but you could be doing more
damage to your body. When you apply bleach directly to the skin, it
removes the top layer causing irritation. Bleach may also weaken
your skin so that your rash may become worse, lead to increased
skin sensitivity and possibly an infection.
Instead of harsh chemicals, use a cleanser designed to remove
the rash-causing oil of poison ivy, oak and sumac such as
Outdoor Skin Cleanser or Tecnu Extreme Poison Ivy
Scrub. Follow up the cleanser with an anti-itch
medication to relieve symptoms such as Calagel Medicated Anti-itch
Gel or homeopathic Tecnu Rash Relief Spray.
