We no longer have pets and want to replace the carpeting. The sub-flooring still has an odor! We have tried bleaching it, Just Rite 1.2.3 Odor Free and now recently Nature's Miracle. NOTHING so far is helping! What can we do without ripping out the sub-flooring? We're stumped! My husband does not want to put down good carpeting, only to have to rip it out again! PLEASE HELP US!!!!!
