Alright, so this is one of those dumb things that slowly drives you crazy but never feels big enough to actually talk about, right? You do a load of laundry—your favorite black hoodie, those leggings that somehow still fit—and it comes out looking like someone attacked it with chalk. White streaks. All over it. Like your washer just gave up halfway through and said, “Good enough.”
I used to think it was the clothes. Or maybe the water. Then I blamed my detergent. Then I wondered if maybe I just wasn’t meant to own black clothing. But nope. Turns out it’s a whole bunch of tiny mistakes that add up to laundry chaos. And yeah, I’m gonna walk you through all of them, mostly because I’ve made every single one.
So Apparently You Can Use Too Much Detergent
Okay, this one still annoys me. You buy detergent, you want your clothes clean, so you pour a big ol’ cupful in there. More soap = cleaner clothes, right? No. Apparently not.
If you go overboard, the detergent doesn’t actually dissolve. It just kinda sloshes around, half-heartedly, and then decides to attach itself to your pants in the form of dried-up white gunk. Especially if the water’s cold. Especially if your washer is one of those “efficient” ones that uses three tablespoons of water and calls it a day.
Fix? Use less soap. I know, groundbreaking. But seriously, you probably only need like… a tablespoon. Maybe two. That full cap? Marketing scam. Unless you’re rolling in mud daily, you’re good with less.
HE Washers: Somehow Both Smart and Stupid
I have one of those high-efficiency washers. The kind that proudly tells you it’s saving the planet while simultaneously not rinsing your clothes properly. Love that journey for us.
The issue is they don’t use a lot of water, which, fine, I guess. But it also means there’s not enough liquid in the drum to fully rinse out whatever soap or softener or dog hair you’ve thrown in there. So stuff comes out with residue. Little white lines that feel… sticky? Dry? I don’t know how to describe it, but you know what I mean.
Anyway. Use the “extra rinse” setting if your machine has one. Or just run the damn thing again, which is annoying but does help. Also—some people swear by tossing a splash of vinegar in there. I’ve tried it. Didn’t ruin anything, so… why not?

Overloading = Laundry Jenga
This one’s on me. I cram as much laundry into the washer as humanly possible because I hate doing multiple loads. If I can close the lid, it fits. That’s the rule.
Except—shocker—when you overload the washer, your clothes don’t actually move around. They just spin like a dense, soggy brick. Which means the detergent doesn’t reach everything, and whatever doesn’t get rinsed off ends up streaked across your leggings.
So, yeah. Don’t pack it full. Give stuff room to swish. Which sounds obvious, but I’ve ignored that advice like… every week for years.
Detergent Not Dissolving? Cool.
So even if you’re using the right amount of detergent, it might still not dissolve. Maybe the water’s too cold. Maybe you dumped the detergent in wrong. Maybe your washer’s just in a mood. I don’t know.
Something that helps? Turn your clothes inside out before washing. I don’t always do it—who has time—but when I do, the streaks are way less annoying. Also, make sure your washer’s filter isn’t clogged. I didn’t even know there was a filter until I Googled “why does my washer hate me.” Turns out it matters.

Fabric Softener Might Be Screwing You Over Too
Okay, this one hurt. I was a big fan of liquid fabric softener. It smells nice. Makes everything feel cozy. But guess what? It leaves behind gunk. Not just in the machine, but on your clothes. Especially darker stuff.
One day I noticed this weird film on my black T-shirts. Thought it was detergent at first. Nope. Softener. Just… sticking to everything like cling wrap with a grudge.
So I stopped using it. Switched to vinegar (again—vinegar is having a moment here), or sometimes I’ll toss in that Lysol laundry sanitizer stuff when I want to feel like I’m doing something extra. Clothes are still soft. No streaks. No regrets.
Use the Right Soap for the Right Machine. Yes, There’s a Difference.
If you have an HE washer, it needs HE detergent. The end. I used regular stuff for months because I didn’t realize there was a difference. Seemed like a scam. But no. The suds level actually matters. Too many suds = not enough rinse = gross white crap on your clothes.
Now I just buy the ones labeled “HE” and sleep a little better knowing the machine’s not having a meltdown every time I wash socks.
Still Seeing Streaks? Hit Rinse Again
Even after you’ve fixed all of this—detergent, load size, water level, etc.—sometimes you’ll still get a rogue streak. Because laundry is chaos and we’re all just trying our best.
When that happens, just run an extra rinse. Yeah, it’s annoying. But it works. Gets rid of the last of the suds or whatever’s clinging to your stuff. And it’s easier than rewashing the whole load and yelling at the drum again.
Honestly, I don’t think white streaks are ever going to completely vanish from my laundry life. But I’ve cut them down a lot just by doing less. Less soap. Less softener. Fewer clothes per load. I guess that’s the theme here: chill out on the “more is better” thing.
And keep some vinegar on hand. Apparently vinegar fixes everything. Laundry. Dishwashers. Relationships. (Okay maybe not that last one.)
Anyway—if your black jeans are coming out looking like they got in a fight with a bottle of baby powder, at least now you’ve got some options. Or, you know, you can just pretend it’s part of the look. I’ve done both.
