Well, let's see. The provided sources are a bit like asking for directions and being handed a brochure for a new car. They're more interested in selling you new sofa covers than helping you with the ones you've got. But fear not, I can help you navigate this domestic minefield.
The short, and admittedly frustrating, answer is: maybe! It's a thrilling game of upholstery roulette, and the outcome depends entirely on a tiny, often hidden, fabric tag on your cushion cover. This tag is the sacred scroll of sofa care, and you must find it before proceeding.
This little oracle will have a cleaning code. If you see a "W," rejoice! That means water-based cleaning is a-go, and you can likely use the washing machine. If you see an "S," back away slowly. This stands for "Solvent," meaning it's a job for a professional dry cleaner only. "W/S" means you can use either, but you should still be cautious. And if you find the dreaded "X," it means vacuum only. Don't even look at it with a damp cloth.
If you are one of the lucky ones with a "W" tag, zip the covers completely shut. Wash them all together on a cold, gentle cycle with a mild detergent—this prevents one cushion from looking like a sun-bleached cousin to the others. And whatever you do, do not put them in a hot dryer unless you're trying to fashion new covers for a doll's sofa. Air-dry them or use a no-heat tumble setting to avoid a tragic shrinking incident that will make getting them back on the cushions an Olympic sport.
