Two questions:
1. Does it make sense to wash them? I never have, didn't think it was a good idea. But my bags, both top and bottom, are starting to let more and more through the material that isn't air. Or they just need to be replaced...
2. Is there anything that could be sprayed on, or that the bags could be soaked in to make less material stick to the inside. I'm thinking more about the top bags than anything. When I do anything that creates alot of fine dust, like the widebelt, the top bag feels "thick" because of all the material stuck on the inside. A couple of shakes and its gone, but that doesn't help while its running.
I've been thinking about building a cyclone which should help, but I'm totally out of space.
