Slicker Brush Failure #1

So I’m having trouble brushing out "fur" on the limbs of my animals. I’ve Googled it, and read different ways on how to use a slicker brush on crochet projects, but alas, no success. I’m sure it’s because I don’t have the right yarn, but I cannot find the Mohair yarn in the colors I need, so I’ve got to settle. I’m using Vanna Choice bulky yarn-yes it’s 100% acrylic, but I’m still hopeful that I can find a site teaching me how to pull out the fuzziness without showing the stitches and rounds. This sucks.
