[EX Q]: 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.
[EX A]: Positive

[EX Q]: What a great album!!! I never knew she sang as well. I have seen her in French movies and enjoyed greatly her acting in those movies. Now I even adore her more, because not only can she act, but she can sing as well!!!Go Charlotte Go!!!! Can't wait for her next album.
[EX A]: Positive

[EX Q]: I've been wearing the waist clincher for the last two years. I purchased a new one recently and it's not the same type of material of the previous ones i've brought. I thought maybe because i had lost weight, so i brought a smaller sizer, but that one didn't fit the same either. I thought i found a miracle when i first purchased the girldle through Amazon, but i have found my recent purchase has surely let me down...
