I've been cleaning my pads with both dawn power dissolver and also regular dishwashing soap. They have come out clean without any stains. I usually let them soak in a bucket of hot water filled with dishwashing liquid and when the water becomes lukewarm, I then knead the pads until they come out clean. Wrinse them out under the sink and spin dry them on your machine. Let them sit overnight in a clean spot and they should be dry to put away in baggies or a pad box.
