I prefer Super Clean over Purple Power, Super Clean seems to be a bit stronger. A quick warning using Purple Power, Super Clean, Simple Green, and similar products- If you soak any painted parts in them for more than maybe a 1/2 hour, it will take the paint off. Also, do NOT use it to soak nay kind of die cast parts. A short soak, scrub, and rinse will be fine, but leaving die cast parts in those kind of cleaners will result in a ruined part, as the dissolve the metal. If you mist soak a die cast part, use Simple Green, as it will only discolor the part, but won't do any major damage. It will remove any paint from it, though.
