What UV Damage Does to Your Car Interior

Prolonged exposure to sunlight leads to:

  • Cracking dashboards and door panels
  • Fading leather, vinyl, and fabric upholstery
  • Brittle trims and warped plastic
  • Increased cabin heat, making your AC work harder

Boston summers may be short, but the UV index can soar. If you leave your car unprotected—even for a few weeks—you’ll start seeing signs of wear.

Using a UV spray like 303 Aerospace is easy and effective. Follow these steps for optimal results:

  3. Wipe evenly across the dashboard, door panels, center console.
  4. Buff gently with a clean microfiber towel to remove excess.
  5. Reapply every 3–4 weeks or after car washes.

💡 Tip: Don’t use on glass or instrument clusters—it may leave streaks.


Other Ways to Protect Your Car’s Interior

Aside from sprays, here are a few bonus strategies:

🧤 Use a Steering Wheel Cover

Prevents hand burns and fading from direct sun.

🪟 Keep Windows Slightly Cracked

Reduces heat buildup but only safe in secure areas.

🧽 Regular Cleaning

UV damage accelerates when dirt and grime are present. Keep your dash clean.

🧼 Apply Interior Coatings

Look for interior ceramic coatings that add an extra layer of UV resistance.
