it's not months old, just from today.. my Mom lives with us and she didn't tell me about it. I went in her room to get something and almost passed out! I've washed the sheets and sprayed Febreeze everywhere, I may wind up mattress shopping this weekend!
) I skip the enzyme and soak the darned thing in straight vinegar and let it dry.first dont pee on the mattress. otherwise, throw it out and buy a new one. it is good for the economy.

We had the Simple Solution stuff (since this is NOT this first time we've found peed-on stuff) and I washed it with that stuff while they were at the school dance, and the smell was completely gone when I took it out of the dryer.
