How to Restore Old Metal Kitchen Cabinet Hinges

Assess the Damage

Before doing anything, inspect each hinge closely to identify issues needing attention. Look for:

• Loose screws or missing screw covers causing wobble
• Rust buildup preventing smooth operation
• Gunk, grease, or grime buildup
• Cracks, chips, bends, or other damage

Make notes on which hinges need which repairs so you can systematically restore them.

Clean the Hinges

Thoroughly clean all hinge components to remove gunk interfering with smooth motion.

• Remove hinge pins and separate the two sides of each hinge.
• Scrub with a wire brush to remove rust and caked-on grime.
• Soak in white vinegar to dissolve grease buildup.
• Rinse well and dry completely.

Lubricate the Hinges

Lubricating helps hinges glide effortlessly again.

• Apply a light machine oil or lubricant spray.
• Work lubricant into all crevices and movable joints.
• Wipe away any drips or excess.

Avoid household oils like WD-40 that can collect gunk over time. Re-lubricate periodically for continued smooth operation.

Reinstall Hinge Pins and Tighten

With cleaned, lubricated hinge parts, reassemble and tighten:

• Insert hinge pins to reconnect both sides.
• Tighten any loose screws securely using a screwdriver.
• Consider applying threadlocker gel to prevent screws from loosening again.
• Replace any missing screw covers.

Check that hinges move freely without wobble after tightening.

Repair Any Damage

For hinges with cracks, chips, bends, or other damage, repair options include:

• Using super glue or epoxy to reattach broken pieces.
• Filling cracks or gaps with wood filler and repainting.
• Replacing significantly damaged hinges with identical new hinges.

Carefully remove damaged hinges and install replacements or make repairs off the cabinets for best results.

Test Operation

Once all hinges are cleaned, lubricated, tightened, and repaired, reattach cabinet doors. Open and close to test operation. Hinges should now glide smoothly without sticking, creaking, or wobbling. Adjust as needed until door motion is restored.

Maintain Improvement

Keep your revitalized metal kitchen cabinet hinges in great shape with:

• Periodic cleaning and lubrication every 6-12 months.
• Swift repairs if new issues arise like loose screws or cracks.
• Adjusting if doors become misaligned over time.

With proper care, your restored hinges can stay smooth and functional for years before needing to replace. Enjoy the savings and satisfaction of salvaging those old cabinets instead of buying new.
