I bought one of these today at Lowes and it works better than any cloth I have used. I have an acrylic and also glass tanks and this thing works perfect on the acrylic so at $3.49 it is worth trying. It didnt leave streaks at all when I used the water asnd vinigar. They say the blue one is best for wet wiping. And no I dont work for them, I just stumbled across it and I like it.
