The residue is minor. A couple quick dunks in a large bucket if water should get any residue off (if there is any) and then dried. There could be a bit of dust but nothing to bad. We got word today that we are getting 3-5 bundles of winter camo in 2 weeks. These weigh close to 70 pounds, so I would expect them to cover 1000 sq Ft area each. More details will be posted on arrival.
