lobewiper

A friend wasn't watching the doggie-box of Chinese while sitting in the back seat, so now my car smells like shrimp with lobster sauce after it fell on its side and leaked. When wiping it up a half-hour after the juice started seeping out onto and through the perforations in the leather, I'm sure I wiped some of it in even deeper while trying to clean it off. Since it still smells after two weeks, I decided to pull the rear seat out and see how hard it would be to cut the hog rings to get to the underside of the leather and to the foam to clean it properly. Looks like a piece of cake, but would appreciate any advice on hog rings/pliers, where to buy them, and anything else you might think of. Thanks!
