If you put the plastic etching container into a larger one with hot water and rock the etch tub back and forth, a small board like this one should etch in under 5 minutes with fresh FeCl3. <br /><br />Also, the Sharpie ink comes off easily with methylated spirits. You can also use metho on a small piece of paper towel as an eraser of markup errors.
