There is a product you can buy called Nature's Miracle-you can find it at most pet store's, and I believe Walmart even has it now. It works really well. If you get a black light-and check out the furniture with it-the soiled areas will show up with the black light. Then use the Nature's Miracle to clean those areas-following the labels instructions. This method works wonderfully. Btw, you can also use Nature's Miracle for stain removal in your laundry. Works great.
