Jeans are made of cotton denim, and cotton loves to shrink under high heat—it’s like it’s on a mission to become a crop top from 2001. The tumbling action in the dryer also stresses the fibers, so your sturdy work jeans start looking like they’ve been through a mosh pit after just a few cycles. And those dryers with “sensor dry”? They tend to overcook your jeans because denim is thick and tricks the moisture sensor. You might pull them out feeling like you’ve wrestled a damp, stubborn cat.
Sidenote: Have you ever noticed how dryers don’t care about your feelings? They just spin and spin, laughing at your laundry.
When It’s Actually Okay to Use the Dryer
Now, I’m not here to be a laundry absolutist. There are moments when the dryer is your friend. If your jeans are 100% cotton and you’re fine with them shrinking a bit (say, they were too loose in the waist), a short, low-heat cycle can help. Or if you’re washing raw denim and want that tight, vintage fit—go for it, but prepare for a snug ride. Dryer balls are also a lifesaver: they fluff the fabric and reduce wrinkles, so your jeans don’t come out looking like crumpled paper.
But never dry jeans with zippers, rivets, or buttons on high heat. Those metal bits can heat up like tiny branding irons and leave scorch marks on the fabric—or worse, scratch the dryer drum. Your machine will hold a grudge.
