The main problem with the smell is it gets into the padding under the rug sometimes even all the way into the wood underneath. When it is really bad or the spot soaked through. You also need to let the product soak through to get to the smell. I suggest saturating it let it sit for 1/2 hour then with towels on the ground over it walk on the stain to soak up the natures miracle. Once the product has been down to were the smell is the smell should go away.
