How to use Hunt carbon fiber brush?

I am going to show my lack of ingenuity by asking this question, but I'm going to do so anyway. How do I use the Hunt carbon fiber brush? I can't seem to pick up all the dust; the brush seems to just collect the dust at one point on the record and I can't pick it up off the record. Also, do I use the brush when the record is turning? I tried that, but the force of the brush stops the platter from spinning. How much force should be applied?

Thanks in advance for answering such a basic question. I'm new to analog and LOVE the sound. Can't believe I spent $5000+ on digital...
