    I don't see the use for vinegar at all- the Dawn is cutting the oil,
    alkaline is better I always say washing soda (sodium caerbonate, but

    Cascade. The formula for this varies with the state it is sold in but
    it will contain washing soda and a sodium silicate ( which is an
    excellent degreaser) -- state to state formula differences will be
