In order to respect the concept of going from the soften option to the harder one and also to maintain the abrassion to the minimum, we use to apply a soft air blow at first and only after a special soft brush that will remove the dust the air blow didn’t do.
I cannot think of any cloth now but am sure there’s something somebody tried and may work, but we enter there in the terrain of things we must do only when we sure gelatin is in good enough shape to resist it.
