How to use the Eraser
Select the Eraser tool. The context panel shows a Size slider.
Set eraser size (1-100 px). Small sizes for precise corrections; large for clearing big areas.
Press and drag over the area you want to erase. Pixels are replaced with white.
Release to finish. Use Undo ( Ctrl+Z ) immediately if you erase too much.

Tips
Use 1-3 px to remove stray pixels or correct edges without disturbing nearby detail.
