How to Wash a King Comforter – The Right Way

Washing a king comforter at home is a nightmare. It barely fits in your washer, it doesn’t agitate properly, it comes out still dirty in spots, and your dryer can’t handle it so it sits damp for hours. Sound familiar? The good news: you can wash a king comforter without any of that hassle.

Here’s how to actually wash a king comforter the right way – whether you bring it to a laundromat or try to make it work at home. The fastest way to wash a king comforter is in an oversized commercial machine.

Why Your Home Washer Can’t Handle a King Comforter

A standard home washer has a capacity of about 4-5 cubic feet, which translates to roughly 15-20 lbs. A king comforter alone weighs 8-15 lbs depending on the fill material. That means your comforter is taking up 50-100% of your washer’s capacity before you even add water.

The result: the comforter can’t move around enough to actually get clean. Water and detergent don’t circulate properly. You end up with a comforter that smells clean on the outside but still has body oils, sweat, and dust mites trapped inside the fill.

And that’s assuming it even fits. Most king comforters have to be crammed into a home washer, which puts stress on the machine’s bearings and suspension. That’s how you end up with a $300 repair bill on top of a still-dirty comforter.

The Best Way: Use a Commercial Washer

Commercial washers at a laundromat are built for exactly this. At The Laundry Spot, we have three machines that handle king comforters easily:

• 60 lb washer ($8.75) – fits a king comforter by itself with room to move
• 80 lb washer ($12.25) – king comforter plus sheets and pillowcases
• 100 lb washer ($14.25) – king comforter plus your entire family’s weekly laundry in one load

The difference isn’t just size. Our commercial machines spin at 165 G-force during the extract cycle. That means your comforter comes out significantly drier than from a home washer, which cuts dryer time in half and prevents that damp, musty smell you get when a comforter takes too long to dry.

Step-by-Step: Washing a King Comforter at a Laundromat

1. Check the care label – most comforters are machine washable, but check for “dry clean only” first
2. Treat any stains – pre-treat visible stains before you leave home. A simple spray-on stain remover works fine
3. Choose the right machine – for a king comforter alone, the 60 lb washer is plenty. If you’re adding sheets and pillowcases, go with the 80 lb. Our staff can help you choose
4. Use the right cycle – select a warm wash with a cold rinse. The touchscreen makes this easy. Avoid hot water on down or synthetic fill
5. Don’t overdo the detergent – commercial machines need less detergent than you’d think. One normal dose is enough. Too much detergent leaves residue in the fill
6. Dry on medium heat – use our 75 lb dryer. Medium heat protects the fill while still drying thoroughly. The comforter will be much drier coming out of our washer than a home machine, so dryer time is shorter
7. Check for damp spots – before you fold it, pull the comforter apart and check the center. If it’s still damp, run another 10-15 minutes

Total time: about 60-75 minutes including wash and dry. Total cost: $8.75-$14.25 for the wash plus $3.00 for the dryer.

How Often Should You Wash Your Comforter?

Most experts recommend washing your comforter every 2-3 months. If you use a duvet cover, you can stretch it to every 4-6 months since the cover is doing most of the work. Pillows should be washed every 3-6 months as well.

If anyone in your household has allergies, wash the comforter monthly. Dust mites, pet dander, and pollen build up in comforter fill and a home washer simply can’t flush them out the way a commercial machine can.

Don’t Want to Do It Yourself?

We also wash comforters through our pickup and delivery service. Schedule a pickup, leave your comforter out, and we’ll wash it in our commercial machines, dry it properly, and deliver it back to your door. $1.75/lb, 30 lb minimum per pickup. Most king comforters with sheets and pillowcases hit the minimum easily.
