I use Pulsar paper and a Laserjet 1020, so might not apply... I had a few messy looking boards at first, once the liquified toner gets onto something, it's tough to get all of it off (hands, clothes, work bench...). Here's how I deal with the mess. I put down newspaper, soak a paper towel well (dripping) with acetone, and try to go over the board quickly and thoroughly, not scrubbing yet, just a quick soaking wipe. Then I scrub, trying to use as much of the clean surface of the paper towel. Usually have the board fairly clean, but usually need to use a second soaked towel to finish it, and will move the board to a clean area of the newspaper if toner gets on it. A can of acetone at the hardware store or even Walmart is around $3.00, so don't be stingy with it. I think if you use too little, the toner is just softened into more of a paste, and doesn't get soaked up into the towel, just smeared around. Wouldn't use cloth, as its pretty much a one use deal, won't wash out in the laundry.
