UGG Disco Slides Sandals Size 9

These definitely need some TLC. I wouldn't know the first thing about trying to clean these without them losing their fluffiness. I'm assuming the soles are supposed to be off white or almost like a grey/cream color? I can't tell. If they are supposed to be white, then they are every dingy. If you think you could clean these up, then here's your chance to get them at a great price. I just need to declutter and want them gone. They look like they could be super cute and comfortable.
