ChatGPT to the rescue! (Working on a vintage mini belt bag.) Has anyone here tried any of these methods with success? Here's the advice from AI:

I'm working on a vintage Coach bag, rehabbing it. The hardware is a pushlock made of brass. It's quite tarnished and I want to take it off the bag to clean it. I have a special two-pronged tool which is supposed to remove it. It won't come off. It seems to be rusted. How can I remove it without hurting the hardware or the leather bag it's connected to?

If your vintage Coach bag’s brass pushlock is stuck due to rust or tarnish and won't come off with the two-pronged tool, here’s a safe step-by-step approach to remove it without damaging the hardware or leather.

Step 1: Lubricate the Mechanism (Break Down Rust or Corrosion)

Since the lock is likely stuck due to oxidation or rust on the screws or fasteners, try applying a gentle penetrating oil to loosen it.

  • Best options:
    • WD-40 Specialist Penetrant Spray (for rusted metal parts)
    • PB Blaster (penetrates deep into rusted areas)
    • Liquid Wrench
    • Mineral oil or sewing machine oil (gentler but slower acting)
  • How to Apply:
    • Dip a cotton swab or precision dropper into the oil and apply it sparingly around the screws and any moving parts.
    • Let it sit for at least 15-30 minutes (or overnight for severe rust).
Avoid spraying directly onto the leather! Apply the oil only to the metal and use a paper towel to protect surrounding leather.


Step 2: Apply Gentle Heat (Expand the Metal)

If the pushlock is still stuck after lubrication, warming the metal slightly may help expand it and break the rust seal.

  • Use a hairdryer on low heat and direct it at the metal only (not the leather) for about 30 seconds to 1 minute.
  • Try the two-pronged tool again while the metal is slightly warm (not too hot to touch).

Step 3: Tap Lightly to Loosen Rust Bond

Using a small rubber mallet or the handle of a screwdriver, gently tap around the fastener while applying light turning pressure with the tool.

  • Do not hammer too hard, just a light vibration to encourage movement.

Step 4: Try a Vinegar or Lemon Juice Trick (If Rust Is Severe)

If the rust is still holding firm:

  • Dip a Q-tip in white vinegar or lemon juice and gently dab it onto the rusted screw area.
  • Let it sit for 15-30 minutes, then wipe off and try using your tool again.
Do not soak the hardware in vinegar—it could discolor brass. Just a light application!


Step 5: Last Resort – Manual Loosening

  • If the screws or rivets still won't turn, use a tiny flathead screwdriver or needle-nose pliers to gently wiggle the hardware back and forth to break the corrosion bond.
Do not force it too hard—vintage brass is soft and can bend or break.


Final Step: Cleaning the Brass Once Removed

Once you successfully remove the pushlock, you can clean and restore it:

  • Brass cleaner (e.g., Brasso, Bar Keepers Friend, or Wright’s Brass Polish)
  • Lemon juice + baking soda paste
  • Rub with a soft cloth or a toothbrush
Do NOT soak brass in harsh chemicals—this can remove the vintage patina.


Summary:

  1. Apply penetrating oil and let it sit.
  2. Use gentle heat to expand the metal.
  3. Lightly tap around the fastener to loosen rust.
  4. Try vinegar/lemon juice if rust is still stuck.
  5. Wiggle gently with a small tool if necessary.
With patience and care, the pushlock should come off without damaging the leather or hardware.

I think I would try the heat and vinegar steps before the oil. It would be hard to keep the oil off the leather.
 
Hi everyone, new to leather maintenance. Been using Bick 4 leather conditioner, it’s a good one on the lighter side. However I also tried Saphir Renovateur which seems to pull dye out of the surface and leaves a sticky residue (probably am using too much). Could someone confirm if they have the same experience and whether the dye can transfer onto clothing, also when Renovateur should be used? Thanks!
 
A huge thank you to whateve for all of my authentication requests! Bick 4 isn’t enough for this lovely bag so I’ll be using Leather CPR and Blackrock soon. Had no idea the strap can be configured 4 different ways until I read the product card that came with it which I find super neat :) View attachment 6148913
You're welcome! I've always loved this style!
