Silence Squeaks, Prevent Rust, and Extend the Life of Your Car Doors with Simple Maintenance!


1. Why Lubrication Matters โš ๏ธ

Ignoring door hinges and locks can lead to costly repairs and daily frustrations. Regular lubrication:

  • Reduces wear: Prevents metal-on-metal friction that damages hinges and lock mechanisms.
  • Stops squeaks: Eliminates annoying noises when opening/closing doors.
  • Prevents rust: Moisture and road salt corrode unprotected metal.
  • Ensures safety: Sticky locks or seized doors can trap you in emergencies.

Key Stat: 30% of door latch failures stem from poor lubrication (NHTSA).

2. Signs Your Hinges or Locks Need Lubrication ๐Ÿšจ

  • Squeaking or grinding when opening/closing doors.
  • Stiff locks requiring multiple key jiggles.
  • Visible rust on hinges or latch assemblies.
  • Door sagging (misaligned hinges).

Pro Tip: Test doors in winterโ€”cold worsens stiffness!

5. Common Mistakes to Avoid ๐Ÿšซ

  • Over-lubricating: Excess grease attracts dirt.

6. How Often to Lubricate โฐ

  • Hinges: Every 6โ€“12 months or after car washes in winter.
  • Locks: Annually or if stiffness occurs.
  • Post-Rust Treatment: After removing corrosion.

Pro Tip: Lubricate hinges during oil changes for consistency!
