I’ve just been flattening a pine chopping board in the drum sander. It’s so resinous that the fabric-based abrasive loading clogged almost instantly with a rock hard, thick layer of resin and sawdust. It was so difficult to remove I nearly threw the roll away.

What seemed to work was doubling over the paper and rolling it between the hands, such that the layer of stuff has to turn through a tight bend and some of it cracks away. I then sprayed on some Maplin electrical contact cleaner, which smells like acetone, and wire brushed away the softened residue. Worked a treat.

Just be aware that wire brushing the sandpaper can produce sparks that may ignite the acetone, so keep back.
