My dad has a 2003 Camry w/ cloth seats, after awhile, it smelled like armpit haha. He bought the car brand new too. He use to baby it, but I want to say (3) years later, he didn't care anymore, he went finishing w/ the car & didn't keep it top notch. Anywho...since I had cloth seats, I poured baking soda on anything that had carpet & cloth, let it sit in the hot sun for a few hours & then vacuumed it. It took away most of the smell, but I still smelled it again on a hot day, so I repeated the same procedure on a different occasion.
I learned this trick from a magazine, they said if you have cigarette smell on a wool jacket, this is the way to get the smell out.
My close buddy told me to cut an apple in half & place it face up in the car, when it's hot out, and the apple will absorb all the smell.
Air fresheners & febreze only hide the smell temporarily. Just like cologne, you still need to shower.
Give these (2) tricks a try, you have nothing to lose, it's inexpensive & you won't ruin anything further.
