This product, although, I haven't used it myself, but heard and read that it works wonders from other people, called Lavilin is said to kill the bacteria that causes odor for a week with only one application.
I was thinking about buying some but some of the reviews on Amazon.com said the new Lavilin in the white container doesn't work the way it used to when it was in their original black container, and that the formula the company use for the new container has been diluted and doesn't work as long as the original one.
So, I decided not to buy it. But if, you guys have a problem with odor, give it a try, and tell me how it works for you.
