What You Should Know Before You Start
Method A: Heat and Peel
- Identify whether the banner is exterior or interior. Exterior banners are easier to treat with heat applied from the outside; interior banners may require limited or reversed heat exposure.
- Clean the area around the banner to remove dirt and grit that could scratch the glass during removal.
- Warm the edges of the banner with a hair dryer on low to medium heat, keeping the dryer several inches away and moving it continuously to avoid concentrating heat in one spot.
- Gently lift an edge with a plastic scraper, a plastic card, or your fingernail, then slowly peel the banner back. If resistance is encountered, reheat the edge and continue peeling in small sections.
- Continue heating and peeling in small sections until the banner is fully detached.
- Wipe away adhesive residue with isopropyl alcohol or an automotive adhesive remover on a soft cloth, then buff the glass with a clean microfiber.
Method B: Chemical Removal for Residue
Use a solvent‑based remover that is safe for automotive finishes and glass. Always test on a small, inconspicuous area first and follow the product’s instructions.
- Test a small patch of the glass with the remover on a soft cloth to ensure no adverse reaction with tint or coatings.
- Apply the remover to a clean cloth rather than directly onto the glass and gently dab the residue. Let it sit for 60–90 seconds to soften the adhesive.
- Gently wipe in a circular motion with a plastic scraper or card to lift the softened adhesive. Avoid metal tools that can scratch the glass.
- Reapply remover as needed and repeat until the residue is gone.
- Clean the windshield with glass cleaner to remove any solvent residue and dry with a microfiber cloth.
