Example Input: It does an excellent job on mildewed wood such as decks and deck furniture without using chemical mode which is the only weak link in an otherwise strong chain. Unfortunately, the only effective chemical solution is chlorine which acts more or less on its own but cannot be used with this machine. Safe cleaners, such as Simple Green are no more effective than when used without them. Other than that, it's a great product.
Example Output: Positive

Example Input: For this kind of movie your not supposed to get bord and skip through most of it. But that's what happened.Only 1 person could act. Most of the women where max 5s. The best part of the movie is the front cover.
