Lighter Restoration: Mistakes I Made and What Experience Taught Me

Restoring vintage lighters is a rewarding hobby, but it comes with a learning curve. When I first started working on old petrol and butane lighters, I made plenty of mistakes. Over time—and after trial, error, and a few flying springs—I’ve learned what works and what doesn’t. If you’re interested in vintage lighter restoration or just starting out with your first project, here are some lessons experience taught me.

1. Springs. When you take apart anything under spring tension, parts will fly—and they can fly far. Vintage lighter springs are small and easy to lose, so keep a finger on the plunger until the pressure is released.

2. Mud. Don’t make mud. Years of grime plus any kind of liquid equals mud—and mud is nasty. Do yourself a favor and get some small brushes. I also use a little blower: a battery-powered air duster and a manual one. Narrow wire pipe cleaners are also great—just make sure to check the dimensions. Many are made for drinkware and too large. Straw cleaners will work in a pinch, but actual pipe cleaners are also very handy. PRO TIP: You can use the manual blower to see if you have a flint jam. If you stick it in the end of the flint tube and air moves freely, you likely don't have a jam. No air, you're clogged.

3. Work surface. Screws, springs, wheels… they all roll—and roll away fast. Make it harder for parts to escape. I like using hand towels to soften the surface, and I find takeout container lids helpful for corralling small pieces. A good workspace makes vintage lighter repair much less frustrating.

4. Have a plan. Before you take a lighter apart, make sure you know how it goes back together. Do some research. If you can’t find any videos or references on reassembly, there’s probably a reason. If you do find tutorials, watch them a few times and only disassemble to a safe point. I’ve learned the hard way by taking a lighter apart too far and not being able to reassemble it.

5. WD-40. My dad always said, “If it doesn’t move and it should—WD-40.” Well, yes and no. Here’s the catch: if you feel like you need to drown a lighter in WD-40, it probably means you need to take it apart instead. Once you soak a lighter—especially the file/flint wheel—it may never light again. Be cautious with any lubricant and keep it away from the wheel.

Fun Story

At a flea market, I once came across a 1950s Japan-made Ronson Standard look-alike. It had clearly taken a WD-40 bath.

I asked the seller how much. He said, “1950s Standard Ronson! $30. VERY GOOD LIGHTER.”

I replied, “First, it’s not a Ronson—it’s Japanese-made. Second, it doesn’t work.”

He argued, “WHAT? It works!” as he pressed the plunger up and down.

I countered, “I’ll give you $5 if I put a flint in it and it doesn’t spark.” Sure enough, I did—and it didn’t.

He still tried for $8, but I reminded him: once it’s drowned in WD-40, it’s done. So I relented him down from $30 to $5.

Lesson: Always take some extra flints shopping with you—you never know when you’ll find a hidden treasure.

✅ Takeaway for Collectors: Vintage lighter restoration is about patience, preparation, and the right tools. Avoid quick fixes like WD-40 baths, protect your workspace, and do your research before disassembly. With time and care, you can bring classic lighters back to life and enjoy the satisfaction of reviving a piece of history.
