I've been watching some videos from a couple of years ago that AG did with Mike Phillips. I've been hearing him say he throws his pads in the washing machine. I couldn't believe it. My pads are a few years old. I use them about twice a year on two cars. After I'm done, I put them in a bucket with the powdered pad cleaner and conditioner and I used the polishing pad brush on them. It's always worked OK, but never gets the pads really clean. It was never able to get all of the Colonite 845 out of my red pads. Last night, I washed them like I wash my microfiber towels, All Free & Clear and an ounce to WG microfiber cleaner (in the liquid bleach section) on the "white clothes" setting (hot wash, cold rinse and a second rinse). I've never seen my pads come out so clean. Even the red pads with years of Colonite 845 no longer smell like Colonite. And the pads come out dryer than when I wash them in the bucket.
