Can isopropyl alcohol damage car paint or interior plastics?

Diluted isopropyl alcohol is commonly used as a paint panel wipe and is generally safe on cured clear coat when used as directed. Stronger concentrations or prolonged contact can strip waxes and sealants, dry out rubber and leather, and damage some plastics, display coatings and soft-touch surfaces. Use dedicated prep products where possible, and keep alcohol away from screens and delicate interior materials.
