The bed we use has a foam pillowtop over a water system. It is a king size bed and it sprang a leak. The water seeped onto the foam under the pillow top and mold and mildew covered the bottom of the foam. We removed the pillowtop and foam underpad and used lysol and non-clorine bleach to try and kill and remove the stain. It did not come out. Any suggestions on how to remove this type of mildew stain? Any help would be appreciated. Thanks in advance - The Bowmans
