Look, we get it: it can be tempting to never want to wash your best cashmere sweaters. Maybe you had a traumatizing moment with stray knitwear making its way into the dryer. Or maybe you just spent a ton on fancy cashmere and don’t want to risk ruining your investment. We’ve all been there. But the fact remains: sooner or later things are going to get stinky or, even worse, stained and you’re going to need to figure out how to wash cashmere sweaters.
Before you ask, yes you can dry clean cashmere sweaters. (You can dry clean basically anything if you really want to, frankly.) In fact, that little tag inside the waist of your sweater would tell you that’s what you’re supposed to do. Dry cleaning’s got a dark side, though: they use a ton of harsh chemicals to get the stains and odors out of your gear. Over time, these chemicals will start to break down the fibers in your favorite sweater and before you know it, you’ll be way worse off than if you just gritted your teeth and learned how to clean a cashmere sweater yourself in the first place.
So let’s get to it. No time like the present to learn how to clean cashmere sweaters after all.
Cashmere may be a versatile material to wear, but it’s delicate as all hell. Makes sense if you think about it; anything that feels that soft would require an equally soft touch to keep it looking its best. So if you were wondering, “can you hand wash cashmere?,” the answer is a resounding “yes, please.”
The process is relatively simple, actually. Start by filling up the tub, the sink, or some other large vessel with lukewarm water. Once it’s full, add in one load’s worth of gentle, cashmere-safe detergent — you’ll find our favorite picks below — and mix it up until you get some suds. Then it’s time to start dunking. Working one garment at a time, dip your cashmere sweaters into the soapy water until they’re fully submerged and swirl them gently for about a minute. You want them good and soaked.
Once all your sweaters are in the tub, leave them to soak for up to 30 minutes. That’ll give the detergent time to do its job. After that, drain the water and rinse off your cashmere thoroughly with cool water. You want to get rid of all the suds.
At this point, you’re going to want to wring out your sweaters. Do not wring out your sweaters. This will stretch out the knit and leave your cashmere deformed and ill-fitting. Instead, ball them up and squeeze as much water out of them as you can. Now you’re ready for drying.
Need to clean your cashmere sweaters, but don’t want to do it by hand? A washing machine is still an option, but there are some measures you should take to keep your cashmere as safe as possible. First off, we’d suggest investing in a mesh laundry bag — that’ll keep the cashmere fibers from coming into contact with the washer’s machinery and wearing or snagging. Second, you’ve got to make sure the machine’s on its gentlest cycle. Make sure the water temperature is set to cold and the spin’s on low, otherwise you risk shrinking or felting your sweaters. Finally, take your sweater out to dry the second that buzzer rings to reduce any creasing. And don’t you dare think about throwing it straight into the dryer.
Where a lot of people go wrong isn’t actually in how they wash their cashmere, it’s how they dry it. Our advice: stay away from the dryer. The hot air inside is notorious for shrinking sweaters down to unwearable sizes, even if they’re set on a supposedly wool-safe setting. It’s just not worth the risk.
For a gentler drying process, re-shape your sweater into how it looked before you began washing, lay it out on a drying rack, and let it air dry. This can take up to 8 hours, or longer if it’s a particularly thick sweater. Yes, it’s a slow process but it’s the only way to ensure your sweater fits properly when all’s said and done.
Speaking of, don’t hang your sweater on a hanger to dry, as that’ll stretch out the fabric. Not to mention, you’ll get these weird bumps on the shoulders from the corners of the hanger. (We’re speaking from experience, here.)
If you need your sweater to dry more quickly, lay it down between two dry towels and roll all three up like a sleeping bag. Then unroll it, replace the towels with fresh dry ones, and repeat. This won’t get all the water out of your sweater, but it will help reduce the amount of time on the drying rack.
And there you have you, you’ve successfully washed (and dried) your cashmere sweater.
The key word in picking the right detergent for cleaning cashmere sweaters is “gentle.” Regular detergents can be too rough, damaging the natural fibers and stripping away cashmere’s sought-after softness. So what you’re looking for are cleaners specially formulated for knits and delicate fabrics.
