Unfortunately, from what I've read, if the oil isn't washed off the animal very soon after its exposure to the oil, the toxins in the oil have already been absorbed into the animal's body and it will die regardless.
Tide Loads of Hope program is the laundry detergent company's way of helping disaster victims. According to the Tide Loads of Hope website:
Tide Loads of Hope helps in the aftermath of a natural disaster by providing clean clothes and a sense of comfort to families in need. Partnering with Feeding America, we travel to disaster affected neighborhoods with the Tide Loads of Hope truck or vans, our free mobile laundry service."
To help fund the program, Tide sells T-shirts like the one pictured below.
Tide Loads of Hope t-shirts are available for $20 (buy two or more and get free shipping). You can purchase them HERE.
