    Re: Soda Blasting For Mold Removal???

    Posted by v on 12/09/06

    Yup yup yup! You can tell these guys are experts. First of all ... You
    don't cook with baking soda. You us BAKING ... POW - DER. Sodium
    bicarbinate doze not kill mold. But if you keep cooking with it, you may
    kill some body close to you. Ask Mary what she uses in her cookies. Chloren
    bleech suppossidly kills mold. As well as BORAX, another mineral that is a
    poisen also used as a cleaner. Good old 20 mule team.
