Hey guys, if you’re like most of the dudes shopping for quality men’s knitwear, you know a good sweater, hoodie, or cardigan is an investment. Whether it’s that buttery cashmere crewneck you grabbed for work meetings or a chunky cotton-wool blend you wear on weekend hikes, you want these pieces to last years—not just a few washes before they fade, shrink, or lose that perfect shape. Men’s Knitwear
As someone who’s been supplying men’s knitwear for over a decade, I’ve seen way too many guys make the same avoidable mistakes when washing their knits. Most of the time, these errors aren’t super obvious—they’re just small, lazy choices that add up to ruined, unwearable pieces. Today I’m breaking down the most common ones I see, plus quick fixes so you can keep your favorite knits looking fresh for ages.
Let’s start with the biggest one by far: throwing your knitwear in with the rest of your laundry, no sorting, no care label check. I swear, I’ve had customers bring back sweaters that shrank so much they now fit their kid’s dog, and the first thing I ask is, “Did you wash it with your towels or jeans?” Nine times out of ten, yeah. Why’s that a problem? Two reasons. First, the care label on every men’s knit is there for a reason—even if it’s just a tiny piece of paper sewn on the inside hem. Half the guys I talk to never even glance at that, right? Some knits need cold water, some can’t go in the dryer, some need hand washing. If you ignore that, you’re playing roulette. Second, washing knits with heavy items like jeans or towels means they’re rubbing against way more abrasion than they were designed for. That fuzz you see on your sweater after a few washes? That’s pilling, and it’s way worse when they’re tumbling around with zippers or rough fabric. I always tell my team, if a customer sends back a pilling sweater and I spot it was washed with denim, I can almost guarantee that’s the cause.
Next mistake: using way too much detergent, or the wrong kind. Dudes, I get it—you want your stuff to smell fresh and feel clean. But over-detergent is a killer for knits, especially cashmere or merino wool. Excess detergent leaves a residue on the fibers over time, making them stiff, scratchy, and even causing them to fade. And here’s a pro tip: don’t use regular laundry detergent for knits. Most regular stuff has enzymes and brighteners that are way too harsh for delicate fibers. I recommend a mild, wool-specific detergent, or even a gentle baby detergent if you’re in a pinch. Way too often, customers ask me why their cashmere feels like sandpaper after washes—nine times out of ten, they used the same Tide they use for their work shirts. Oh, and another thing: never pour detergent directly onto the knit. That can cause discoloration or even a spot that won’t come out. Always dilute it in water first, then add the sweater to the soapy water.
Then there’s drying knits wrong. So many guys see a “hand wash” label and think, “Great, I can just throw it in the dryer for 20 minutes to speed it up.” Stop. Just stop. Heat is the enemy of knits. Hot water (or even warm water) causes shrinkage, and the dryer’s heat will turn a perfectly fitted medium sweater into a crop top. Even if you have a “low heat” setting, the tumbling action alone can stretch out the shoulders and neckline. The right way to dry? Lay it flat on a clean towel. Wait, not just any towel—use a thick, absorbent one (old cotton bath towels work) and roll the sweater up with the towel to squeeze out excess water. Don’t wring it, that’s another mistake! Wringing twists the fibers and can permanently warp the shape. Once you’ve squeezed out most of the water, lay the sweater flat on a drying rack or another clean towel, reshaping it to its original size—stretch the shoulders a little, pull the hem straight, adjust the cuffs. Let it air dry away from direct sunlight (sun fades colors fast, especially dark knits like navy or charcoal). I’ve had customers come to me with a cardigan that used to fit their broad shoulders, now it’s tight across the chest and sagging at the hem—9 times out of 10, they hung it on a hanger to dry, and the weight of the water stretched it out. Hangers are for button-downs, not knits.
Another one: ignoring pilling and using rough tools to fix it. Pilling is totally normal, especially with cotton or wool blends, but a lot of guys make it worse by using a razor or a rough fabric shaver that’s too aggressive. Those can snip the actual knit fibers, leaving holes or fuzzier spots. The correct way is to use a gentle de-piller specifically made for knits, or a sweater stone (they’re cheap and work way better than a razor). Run it lightly over the pills, not back and forth too hard, and you’ll remove the fuzz without damaging the fabric. Pro tip: do this before the pills get super bad—once they’re thick, it’s harder to fix, and more likely to cause damage.
Wait, what about mixing colors? I know you’ve heard this before, but it’s worth repeating. Even if you think a light gray sweater is “safe,” if you wash it with a brand new red hoodie, that red can bleed onto your gray and turn it pink. I’ve had so many guys panic when their new white crewneck turned light blue after a single wash with their son’s blue socks. Always wash dark knits separately from light ones, and test new colors for bleed before washing them with anything else. Just dab a little water on the inside seam of the new item, press with a white towel—if color comes off, hand wash it alone the first few times.
And here’s a weird one I see all the time: over-washing. Dudes, your knitwear doesn’t need to be washed after every single wear. Unless you spilled coffee on it or it got super sweaty (like, gym-level sweaty), you can wear a sweater 3-5 times before washing it. Knits’ fibers have natural oils that keep them soft and shape-resistant, and washing too often strips those oils, making them fade, shrink, and get scratchy. I have a customer who’s been wearing his merino wool cardigan 3 times a week for over two years, and he only washes it once a month. It still looks almost brand new. That’s the secret. If it just smells a little musty or has a faint stain, spot treat it instead of washing. Spot treating: dab the stain with a little mild detergent and cold water, let it sit for 10 minutes, then gently blot with a clean towel. No need to throw the whole sweater in the wash.
Now, let’s talk about what to do if you do make a mistake. Did you shrink your sweater? Don’t panic—you can sometimes stretch it back. Dampen the sweater a little, then lay it flat, gently pulling the shoulders and hem to the original size, and let it air dry that way. If it feels stiff, you can use a wool conditioner after washing, which adds back those natural oils. And if you’re ever unsure about a care instruction, just check the label—we print all of ours clearly, with easy-to-follow symbols, and if you have questions, don’t hesitate to reach out.
