Is there a chemical that "undos" highlighters(yellowish thing)?
Well, this is an insufficient question, I suppose. Yellowish light can be absorbed by viewing from a blue glass (cobalt glass, as we call it), but the process is purely physical. The chemistry is in synthesizing or employing the blue chemical on the highlighter. Since the question is incomplete, my answer is incomplete, too.
Is there a method I can get the yellowish thing off the page... sorry i'm no pundit on this matter so my question may sound absurd and be incomplete.
