I belong to the Omar Khayyam school of erasures. He wrote, "The moving finger writes, and having writ moves on; nor all they piety nor wit shall call it back to cancel half a line, nor all they tears wash out a word of it."
Sorry, kiddo, but if you don't want to apply White-out, Tippex, or an eraser, you're probably stuck with it. It's difficult to erase something without trace.
