Hey everyone! If you\u2019re part of the climbing, outdoor, or even industrial gear game\u2014you know how frustrating it is to pull a carabiner out of your bag that\u2019s got that weird, fuzzy rust spot on it. I run a small Carabiners & Clips supplier, and trust me, I\u2019ve been there. Last year, I stocked a batch of aluminum screw-gate biners that sat in a warehouse storage nook for a few months, and by the time my wholesale customers picked them up, like 10% had surface rust that made \u2019em look beat before they even left the building. I spent way too much time troubleshooting, testing different hacks, and even consulted a metallurgist buddy of mine to get the science right (no, I didn\u2019t just Google \u201chow to not rust carabiners\u201d and call it a day). Carabiners & Clips<\/a><\/p>\n

<\/p>\n

First off, let\u2019s cut the BS: not all carabiners rust the same. I get questions all the time about steel vs aluminum, right? Aluminum biners are way lighter, but they form that protective oxide layer naturally\u2014only if they\u2019re not sitting in moisture that breaks that layer down. Steel biners (the ones you use for heavy industrial rigging or big wall climbing) are the rust magnets because they\u2019re mostly iron, and iron + oxygen + H2O = rust, full stop. That\u2019s basic chemistry, but most people miss that the tiny gaps in the gate, the screw mechanism, or even the small scratches on the body are where rust starts. Scratches are like tiny doors for moisture to get to the iron underneath, so storing a biner that\u2019s all scratched up isn\u2019t just a cosmetic issue\u2014it\u2019s a durability issue, too.<\/p>\n

Now, let\u2019s get into the actual storage stuff that I\u2019ve tested, that works, and that I now preach to every customer who buys biners from us. I don\u2019t do the fancy, expensive \u201crust-proof\u201d storage units unless it\u2019s for bulk heavy-duty steel biners for industrial clients. Most of this is stuff you can grab at a hardware store or order online, no fancy budget needed.<\/p>\n

First, let\u2019s talk about the enemy: moisture. Rust doesn\u2019t happen without water vapor, even if you can\u2019t see it. A lot of people leave their carabiners loose in their gear bags, right? You throw in wet ropes, sweaty gloves, a water bottle that leaked\u2014all that moisture is just hanging out, wrapping around every biner. Even if you just cleaned a biner and thought it was dry, if you toss it in a bag with other gear that\u2019s got even a tiny bit of dampness, you\u2019re gonna get rust. I did a test last month: I took two identical steel biners, wiped one down with a microfiber until it was bone dry, put it in a plastic tub with a silica gel packet, and left the other loose in a gear bag with a slightly damp chamois. After 3 weeks, the loose one had a surface rust spot on the screw, the tub one was totally fine. That\u2019s a small test, but it\u2019s proof.<\/p>\n

So, step one for storage: don\u2019t let biners sit loose in dark, damp spaces. Most people know this, but they ignore it because it\u2019s easier to just toss \u2019em in the bag. But if you\u2019re storing gear long-term (like if you\u2019re a climber who stashes biners for next season, not grabbing them every weekend), this is non-negotiable.<\/p>\n

Now, what to store \u2019em in. I\u2019ve tried plastic bags, canvas gear bags, metal boxes. Let\u2019s break it down. Canvas bags are actually bad if they\u2019re not fully dry first\u2014they hold moisture, like a sponge. I learned that the hard way with a batch of aluminum biners a while back; I put them in a canvas gear sack that I\u2019d used on a damp trail, and a week later, there was tiny rust on the gates. Plastic is better, but not just any plastic. Clear zip-top bags work, but you have to squeeze out all the air first. Wait\u2014why air? Because air has moisture in it, especially if you\u2019re storing in a basement or a garage where humidity\u2019s higher. Squeezing the air out creates a mini environment that\u2019s low-moisture. Pro tip: if you\u2019re storing steel biners for months, put a single silica gel packet (the ones you get in shoe boxes or electronics) in each zip bag. Silica absorbs up to 40% of its weight in moisture, so it\u2019s like a tiny dehumidifier for each biner. I buy bulk silica gel from a industrial supply site, it\u2019s way cheaper than the tiny ones, and I throw a handful in each bulk storage bin for our shop, too.<\/p>\n

Another option: hard plastic tackle boxes. Wait, not just any tackle box\u2014get one with a sealable lid. The ones with the rubber gaskets on the lid keep out humidity way better than open-topped ones. I have a set of these for my personal climbing biners, and I label each compartment by type (screw-gate, quickdraw biners, steel rigging biners) so I don\u2019t have to dig through a pile, which scratches them (another rust trigger). One thing I hate is people stacking biners on top of each other without any separation\u2014metal-on-metal contact can scratch the finish, and also trap moisture between the biners. So in the tackle boxes, I use small pieces of foam or even the cardboard inserts that come with new biners (don\u2019t throw those away! They\u2019re free separators) to keep each biner spaced out. I once skipped that step and had two steel biners rub together in storage, and the scratch line turned into a rust line within two weeks. Not worth it.<\/p>\n

Wait, what about oil? I\u2019ve had customers ask if they should coat their biners in WD-40 or light oil to prevent rust. Let\u2019s be real\u2014climbers and riggers don\u2019t want their gear greasy, especially if you\u2019re clipping to a rope or using it on bare skin. Grease also attracts dirt and dust, which is another issue. My metallurgist friend said that for short-term storage (like a month or two), a very light coat of food-grade mineral oil works on steel biners, but you have to wipe it off completely before you use the biner. For aluminum? Don\u2019t do it. The oil will clog the tiny gaps in the oxide layer, and aluminum is soft, so you might leave residue that\u2019s hard to get off. I tried WD-40 on a test biner once, and when I went to use it, my rope got all gunked up. Worst mistake. So oil is a no-go for most people, unless you\u2019re storing steel biners long-term and have a way to degrease them before use.<\/p>\n

Now, what about pre-storage prep? You can\u2019t just toss a dirty, mud-caked biner into storage and expect no rust. That\u2019s like leaving a wet towel in a drawer and wondering why it smells. If you\u2019re storing biners for more than a week, you gotta clean \u2019em first. For aluminum biners: use a mild soap (dish soap works, just no harsh chemicals) and warm water, scrub off any dirt or grime, dry immediately with a microfiber towel (cotton towels leave lint, which traps moisture\u2014fun fact!), and then let them air dry for 30 minutes in a dry, sunny spot (sunshine kills surface moisture and doesn\u2019t scratch). For steel biners: same soap and water, but you can use a soft nylon brush to get into the gate and screw threads, then dry right away, maybe a quick wipe with that food-grade mineral oil I mentioned if you\u2019re storing them for a while.<\/p>\n

Wait, another mistake people make: storing biners in a garage or basement. I live in Portland, OR, where it\u2019s damp 8 months out of the year, so my garage is a no-go for long-term gear storage. If you have to store gear in a place like that, get a dehumidifier for the space. I have a small dehumidifier in my bulk storage room, and it keeps humidity at around 40-45%, which is perfect for biners\u2014no moisture buildup, no rust. If you don\u2019t have a dehumidifier, put your storage bin on a shelf above the floor, not on the ground. Concrete floors hold moisture, so even if the rest of the space is dry, the bin sitting on the concrete is gonna get damp over time. I learned that when I stored a batch of biners on my basement floor once, and they all had minor rust on the bottom of the bodies. Moving \u2019em up a shelf fixed that instantly.<\/p>\n

What about quickdraws? Everyone has those quickdraws with two biners on a nylon sling. Storing those is a whole different thing. I used to just bunch up quickdraws and toss \u2019em in a bag, but the nylon sling holds moisture, so the biners attached to them get rusty. Now, when I store quickdraws, I hang them on a foam pegboard rack in my dry storage room. Hanging them keeps the sling stretched out so it dries faster, and the biners aren\u2019t touching anything. No more metal-on-metal, no more trapped moisture. That\u2019s a game-changer for quickdraws. I bought the pegboard from a hardware store, and the pegs are just the plastic ones, super cheap. I hang each quickdraw by the sling loop, so the biners dangle free. No rust spots on quickdraw biners since I started doing that.<\/p>\n

Wait, let\u2019s test another myth: do stainless steel biners rust? I get this question all the time. Stainless steel isn\u2019t rust-proof, it\u2019s rust-resistant. It still has iron in it, and if it\u2019s exposed to salt water (like if you take it climbing at the coast or work at a marina) and not dried, it can rust. Salt is a huge culprit for rust, by the way. Salt breaks down that protective oxide layer on aluminum and accelerates rust on steel. If you\u2019ve got biners that came in contact with salt, you gotta rinse them with fresh water before storage, no exceptions. I once had a customer send back a batch of coastal steel biners that had rust spots, and they told me they just hosed them off with salt water at the beach and put \u2019em in their gear bag. When I tested that, the salt water left residue on the biner, and within 10 days in storage, rust started. So salt = bad.<\/p>\n

Now, let\u2019s talk about what we do at Carabiners & Clips when we\u2019re prepping orders or storing our own inventory. We don\u2019t just stack biners on pallets. Our bulk steel biners go into sealable plastic totes with silica gel packets, and the aluminum biners go into separate totes because they don\u2019t need the oil treatment. We check the humidity in our storage room every week with a cheap hygrometer (you can get those on Amazon for like $10) to make sure it\u2019s under 50%. We also inspect every biner before it goes out to make sure there\u2019s no surface rust, but we also include a little sticker with storage tips for long-term use, because we know even the best gear can get rusty if you store it wrong.<\/p>\n

Here\u2019s the thing: rust isn\u2019t just cosmetic. For carabiners, especially if you\u2019re using them for climbing or rigging, rust can weaken the metal over time, which is a safety issue. I don\u2019t mess around with that, so I make sure all my customers know how to store their biners properly. If you\u2019re a casual climber who uses biners once a month, you don\u2019t need a fancy setup\u2014just wipe \u2019em down, make sure they\u2019re dry, and toss \u2019em in a sealed plastic bag with a silica gel packet if you\u2019re not using them for a while. If you\u2019re a rigger who has a whole fleet of steel biners, invest in that sealable tackle box and the dehumidifier, it\u2019s worth it to not have to replace rusted gear.<\/p>\n

Wait, I should mention one more thing: don\u2019t leave biners in your car, especially in the summer. Your car can get up to 140 degrees F in the sun, and hot air holds more moisture, so that\u2019s a perfect recipe for rust. I learned this when I left a set of biners in my trunk after a rainy climbing trip\u2014when I pulled them out, the screw gates were all fuzzy with rust. Never again. If you\u2019re traveling with gear, keep it in your living space, not the car.<\/p>\n

<\/p>\n

At the end of the day, storing biners to prevent rust isn\u2019t that complicated. It\u2019s just about keeping moisture away, not scratching the metal, and prepping them before you store them for more than a few days. If you have more questions, or you\u2019re looking for bulk biners that are built to last, don\u2019t hesitate to reach out for a procurement consultation. I\u2019m always happy to talk gear, whether you\u2019re a small gym owner, a rigging company, or just a climber needing a new set of biners. We\u2019ve got a wide range of aluminum and steel biners for every use, and we can help you pick the right ones based on how you use and store them.<\/p>\n
