I developed a poison ivy rash one week ago. With doctor prescribed steroids I was almost completely healed this week. However, I now have a new rash that is more intense and more widespread than the original one. I understand that the oil can linger and that I must clean it up. Is there a visual method to detect the oil? Are there any products that will make it change color or some other distinguishing characteristic?
I do not want to get too paranoid and start cleaning or throwing out everything in my house. A method to narrow my search efforts would be greatly appreciated.
