Hi Karen,
Go to Sally's Beauty Supply. Back in the perm section there is a shampoo called "Curl & Lock". This shampoo removes the smell from acid perms. We've used this shampoo to take out skunk on a cat that was sprayed point-blank, cat pee on our own floors, and of course I always use it on anyone I give a perm. You may have to squeeze this directly on the floor and leave it just sit for an hr or so, and then you'll have to clean up the bubbles for a length of time after, but I'm pretty sure it will be worth the effort. Best of luck! Let us know if you get rid of the smell.
