In that case, press the kneaded eraser into the area to pick up the excess graphite before rubbing the area with it . If the pencil mark is light gray,l there may be more clay mixed with the graphite making the line more embedded into the fibers and denting the paper. If the line is persistant, I use the white elaser c found on the end of the Pentel Clicker mechanical pencils . Because it it whlte it is not likley to discolor the paper as a Pink type eraser might. If you fine you need to apply prassure to remove the graphite , place something thin and hard under the area you are erasing to prevent denting the page or the page underneath. A hotel room plastic entry card or something else hard ,thin and smooth to protect the page and the page beneath. . Check you are not overly destroying the paper fibers as you erase.
