Chalkboard Dust Wipe
Dry wipe makes haze. Wet cloth heals black. The ending is a dark clean field. Not a class.
Why erase instead of write
After a class the board is leftover language. The useful motion is taking it off. Dry first, then wet, until the field is only slate.
How the two cloths differ
Dry wipe smears pale dust into the air. Wet cloth darkens the same path and clears it. Fresh marks puts leftover strokes back if you want another pass.
How to use it
Choose Dry wipe or Wet cloth. Drag. Listen for squeak or cloth. Stop when the field is dark enough.
Limits
Not handwriting practice. Not a claim about end-of-day recovery. Dust and slate only.
