Why does a Sharpie vanish from a Ziploc bag while an expensive paint pen wipes off a pencil case? This episode digs into the two completely different chemical failures behind those frustrations: low surface energy plastics and release agent contamination. We break down the four surface categories you need to know — porous, low-energy plastic, high-energy non-porous, and outdoor — and explain exactly which markers (and which solvents) work for each one.
