Toss in the wash with cold water. Air dry. Boom.
Disappointing
"These were cute, for the first two weeks. Then they got dirty, and I washed them, because they’re “washable” and they stayed dirty. Nothing unusual got on them, just dirt from regular wear. They’re decently comfy, but they slip off too easy. I don’t even wear them anymore. It’s been a year and honestly I’m just upset I spent the money. The other style I got were a little better, but also definitely not worth the money, even on sale."
