Hey there, sunglasses lovers! If you’ve ever spent a sunny day running errands, hitting the beach, or even just wandering around the city with your favorite metal-framed shades, you know that one part of the pair that always gets overlooked? The hinges. I’m not just some random blogger here— I’ve been in the metal sunglasses game for over a decade, so I’ve seen firsthand how grime, oil, and even a little rust on those hinges can turn a $200 pair (or a trusty budget pair you grab every morning) into something that feels clunky, sticks when you open them, or even slips off your face mid-conversation. Today, I’m breaking down exactly how to clean those metal hinges like a pro, no fancy tools or weird chemicals required— and since I’m in the business of making and selling these frames, I’ve tested every single trick here on my own products, so you know it works. Metal Sunglasses
First off, let’s talk about why those hinges get so gross, anyway. Metal sunglasses hinges are made from stainless steel, titanium, or sometimes brass (for budget pairs)— all sturdy, but they’re tiny. The gaps between the two hinge leaves, where the screw sits, are like magnets for stuff you don’t want: sunscreen residue, body oil, dirt from your shirt, even leftover hand sanitizer if you’re washing your hands a lot. Add in humidity or if you sweat a ton, and suddenly you’ve got a sticky gunk that doesn’t just look bad— it’s why your shades won’t open all the way, or make that annoying squeak when you adjust them. I’ve had customers message me saying their new pair got clunky after a week— 9 times out of 10, it’s just a dirty hinge, not a broken one. That’s the good news! You don’t need to replace the whole frame, just spend 5 minutes with stuff you probably already have at home.
Wait, hold on— before you grab anything, a quick pre-clean check. Not all metal hinges are the same! If your pair is high-end titanium or surgical stainless steel, you can use basically anything, but if they’re brass or have a tiny coated finish (like matte black), harsh scrubbing or strong chemicals can scratch that. I always tell my team to test any cleaner on a tiny, hidden part of the frame first— like the inside of the temple arm that touches your headband— to make sure it doesn’t discolor. Skip anything with bleach, ammonia, or oven cleaner, obviously. That’s a no-brainer, but you’d be surprised how many people grab that because it’s in the pantry and start scrubbing. Don’t do that.
Now, let’s get to the actual cleaning steps, starting with the gentlest, easiest method (for when it’s just a little grime) and moving to the deeper cleans for when it’s been a few months.
First, the Quick Daily Clean (for minor buildup): Grab a clean, soft microfiber cloth— the same one you use for your sunglasses lenses works! Fold it up so it’s thick, then gently rub around the hinge in a circular motion. Wait, why “around” instead of directly into the gap? Because if you poke too hard, you can push the grime deeper into the hinge, which makes it way harder to get out later. If the gunk is a little more stubborn, dampen a tiny corner of the microfiber with warm water (just a drop, don’t soak it) and give it the same gentle rub. I do this every time I put my shades away at the end of the day— takes 10 seconds, and my hinges never get too gross. Pro tip: Don’t use paper towels or napkins! They have tiny wood fibers that can scratch the metal, leaving little scratches that will catch more dirt later. Trust me, I’ve had a handful of customers send me photos of that over the years.
Next up, the Deep Clean (for when your hinges are sticky or squeaky— like you haven’t cleaned them in months). This is my go-to method, and I’ve used it on hundreds of pairs before they ship out to make sure they’re perfect. You only need three things: a small bowl of warm (not hot!) water, a drop of mild dish soap (the kind you use for dishes, not the antibacterial kind with fancy scents), and an old toothbrush— the soft-bristled kind, not the hard one for scrubbing tiles. Here’s the play-by-play: 1) Take the toothbrush and dip only the tip of the bristles into the soapy water, so it’s not dripping. 2) Hold the frame so the hinge is facing up, and gently brush the bristles back and forth in the gap of the hinge, not just on the surface. Do this for 10-15 seconds per hinge, don’t scrub like you’re scrubbing a burnt pan. 3) Once you’ve brushed both hinges, dip a fresh corner of your microfiber cloth into plain warm water, and wipe off any soapy residue from the hinge and the surrounding temple. 4) Now, the most important step: dry it immediately! Metal hates sitting wet. Grab a dry part of the microfiber and press the hinge dry, getting into every little gap. If you leave water there, it can cause tiny rust spots over time, especially on lower-grade metal. I’ve had a few pairs come back from customers saying “my hinge rusted” and it turned out they left the shades in their car wet for a week— this method prevents that.
Wait, what if the hinge is really stuck— like it’s not moving at all, or there’s that weird yellow gunk from sunscreen that’s baked on? Then we need to go to the Heavy-Duty Deep Clean, and this is where I recommend something super mild that won’t damage metal: rubbing alcohol (70% is best, the kind you can get at any drugstore). Don’t use 90% or higher, that’s too harsh. This stuff dissolves sunscreen residue and oil like nothing else, and it evaporates fast so no water spots. Here’s how to do it safely: 1) Put a tiny bit of rubbing alcohol on a cotton swab— just a drop, not so much that it drips. 2) Gently twist the cotton swab into the hinge gap, don’t force it. Twist it around a few times, you’ll see the grime start to come off on the cotton. 3) If there’s still gunk, take the soft toothbrush I mentioned earlier, dip the tip in rubbing alcohol, and give the hinge a very light brush. 4) Immediately wipe the hinge with a dry microfiber cloth to get rid of any leftover alcohol. I only use this method every 2-3 months, max, because it’s a little more harsh than soap and water, but it’s perfect for when a pair has been neglected. Just don’t use this on coated frames— like if your sunglasses are matte black or have a colored finish, the alcohol can strip the coating over time. Test that hidden spot I told you about first!
Now, a huge mistake I see people making: oiling the hinge after cleaning. Wait, should you oil it? Yes, but not with WD-40. That’s a big no. WD-40 is for locks and garage doors, not sunglasses hinges. It’s thick, it leaves a greasy film that will attract more dirt within a week, and it can damage the metal finish. Instead, use a tiny bit of silicone lubricant— the kind that’s made for eyeglasses, or even just a drop of mineral oil or baby oil. Here’s how: after you’ve cleaned and dried the hinge, open the temple all the way, put one tiny drop of oil on the hinge pin (the little screw that holds the two hinge parts together), then open and close the temple a few times to work the oil in. Wipe off any excess oil with your microfiber cloth— you don’t want it on your lenses or your skin. I only recommend oiling once every 6 months, unless you use your shades every single day. Too much oil will just turn into a dirt magnet again.
Now, let’s talk about some common problems people run into with hinge cleaning, because I get these questions all the time. First: “Can I take the hinge screw out to clean it?” Most of the time, yes, but only if you have a tiny screwdriver (like an eyeglass screwdriver set) and you’re comfortable doing it. If you’re not, don’t— you can strip the screw or bend the hinge. If you do take it out, clean the screw with a cotton swab dipped in rubbing alcohol, then put it back in. But I’ve found that 90% of the time, cleaning the outside and the gap without removing the screw works just as well, so save taking it apart for when it’s super stuck. Second: “What if there’s rust on the hinge?” If it’s just a tiny spot, you can gently rub it with a cotton swab dipped in a little baking soda mixed with water— make a paste, rub it on the rust, then wipe it off immediately. If the rust is big, that’s a sign you left water or sweat on it for too long, and you might need to replace the hinge. But don’t panic— that’s rare if you’re following the drying step I told you about. Third: “How often should I clean my hinges?” If you wear your sunglasses every day, once a week for a quick clean, and a deep clean every month. If you only wear them on weekends, once a month quick clean and every 3 months deep clean. That’s easy to stick to.
As someone who’s been in the metal sunglasses industry for years, I can’t stress enough how important this is. A lot of people think the only thing that matters is the lenses or the frame design, but the hinge is what makes your sunglasses functional. If your hinges are clunky, sticking, or squeaking, you’re way more likely to lose them or end up with a pair that feels like a hassle to wear. I’ve had customers tell me after following these steps that their 2-year-old pair that they thought was trash works like new again— that’s the best part of my job.
If you have a favorite pair of metal sunglasses that’s been giving you hinge trouble, or if you’re looking for a new pair that’s built to last (we use surgical stainless steel for most of our frames, so rust is basically non-existent if you clean them), don’t hesitate to reach out. We’re always here to help with any questions, whether it’s about cleaning tips or picking the right frame for your face. No question is too small— I’ve answered everything from “how do I adjust the nose pads” to “can I wear these in the pool.”
Wait, one last quick tip I learned the hard way: don’t clean your hinges right before you go out. Wait an hour after cleaning, so any moisture or oil can fully dry, so you don’t get streaks or greasy spots when you put them on. I once cleaned my hinges, threw them on my face, and had oil smudges right in the middle of the lens that took forever to get off. Oops.
Alright, that’s all I’ve got for today! Hopefully these tips save you from having to toss a perfectly good pair of shades, or at least make your go-to pair feel like new again. If you’re ready to grab a new pair of metal sunglasses that’s easy to maintain, or just want more details on hinge care, don’t be shy to get in touch. Let’s keep your shades working great, and keeping the sun out of your eyes.
