How do you properly clean a vehicle before applying tint?

Proper vehicle surface preparation is one of the most important steps in window film installation. A clean application surface helps ensure proper adhesion, reduces contamination, and improves long-term film performance. Professional installation by a 3M Authorized Installer is recommended for best results.

To properly clean a vehicle before applying window film:

1. Wash and dry the vehicle thoroughly
   Remove surface dirt, dust, and debris using standard automotive wash methods. Ensure the vehicle is completely dry before moving to the next step.

2. Clean the application area with a solvent-based cleaner
   Wipe the glass and a generous surrounding area using a solvent-based cleaner. Wipe dry as you work to prevent residue or streaking.

3. Final wipe with Isopropyl Alcohol (IPA)
   Use a 2:1 mixture of Isopropyl Alcohol and water for a final cleaning pass. This step removes oils, residues, and remaining contaminants. Wipe dry immediately using lint-free towels.

4. Use professional surface prep tools when available
   For consistent results, installers may use the 3M Surface Preparation System along with lint-free paper towels to clean the application surface.

5. Ensure the surface is completely dry
   Before film installation begins, confirm that the glass is fully dry and free of contaminants.

For complete installation and cleaning procedures, always refer to the applicable 3M Instruction Bulletins.
