Is there a chemical that "undos" highlighters(yellowish thing)?
The discussion centers on the challenge of removing highlighter marks, specifically the yellowish ink. It highlights that while viewing through cobalt glass can absorb the yellowish light, this method is purely physical and does not chemically remove the ink. The conversation indicates that a chemical solution for "undoing" highlighter marks is not straightforward and requires a deeper understanding of the chemistry involved in the ink's composition.
