I can't seem to get the smell of pee out of the carpet in the bedroom. My ds had an accident (we sometimes sleep on the floor on a mat together). I didn't realize it had gone through the mat and gotten into the carpet, and I think by the time I did notice, it had really soaked in. I've tried soap, baking soda, enzymes...I can't seem to get rid of it. I'd be glad for ANY and ALL suggestions. This is a rental, otherwise I'd rip out the carpet. Thanks.
