One gentleman I met used a kind of rake on a roller. It was hand held and he would roll it back and forth for a minute or two on the terry with it still on the buffer. No the buffer was not operating. The rake/roller loosened the residue and fluffed the terry up. I asked where one would get this and he wasn't too clear with me. It may have been a tool for another application.
