I got an electric blanket for Christmas, and it sheds little ball of fabric sour. Any ideas? I cant dust it in the washer. Any suggestions?
Answers:    what more or less one of those things that you take across your clothes that get fuzzies off?? i don't know what its call though. the end you whip across the material is metal and have a little item on the other side that collects what comes off of it, hope this help
same thing is arranged to me. a lint roller is doing the trick.
