Do you erase pencil markings in books?
When erasing pencil marks on LGB's I recommend holding the page down firmly with your fingers. The reason for this is that if you don't you may wrinkle or rip the page. Whenever possible always erase in the same direction. My ersaser of choice is the grey neading eraser, but I also use a pink or the white rubber erasers. I like the greay because it seem to get into the indentations left they the pencil better then the others.The white eraser is good when the grey doesn't work but depending on the paper the pink can leave a pink stain. If the marks were made by a hard pencil you're still going to have an imprint on the page. When erasing remember to erase as softly as possible. Don't try to remove it all in one rease, all you'll end up doing is ripping the page.
