I use the DP pad cleaner - the powder stuff that mixes into a bucket of water. Handy when you can't get to the cleaning part right away. As far as dedicated pads, I get the idea that a lot of the pros segregate their pads as to the type of product used. I tend to just use polishing pads for polish, whether it's Meguiars #83 or #105, and the finishing pads for the lighter polishes such as meg's #205. I have some blue, red and black pads for the final finish, but I have yet to use them. I think the rationale for the separation is that sometimes you may not get 100% of the product out of the pad. I could be wrong. Pads take a lot of cleaning, regardless of the method used.
