If you use fleece, do you wash it differently? I took some classes on fleece, several years ago, and they explained the way fleece is made. Which is with recycled plastic and polyester; that's why the fabric wasn't around until we started recycling, but with the plastic combed into the polyester, they told us to only use powder detergent as a liquid detergent or fabric softener liquid will just create a film and continue to build up. This is also a problem if using fleece for young children that still have accidents--the odor will stay until powder has kind of cleaned the fibers. Does anyone know if this information is different? I've never used it for batting or backing because I didn't know how it would clean.
