Removing Sawdust from Microfiber Furniture?

I have a microfiber sofa and love seat, that are two months old. The color is beige. I have no problems getting stains out. My husband has a woodshop and sawdust gets on the furniture. How can I get it off? I have tried to vacuum it, but it just does not come off. I have to take a damp towel and almost beat the sofa to make the dust come off. My cushions are not removable. Any help would be appreciated.
