These are bar none these best cleaning pads I've ever used. They also come in a mitt form as well. They don't hold on to dirt at all so there's no chance at scratches (I've never had any from using them). I have tons of Griots stuff. It's all fantastic, especially the polisher (made by Makita). The clay is by far the best I've used too...
