Neutralizing Rust Dyed Fabrics and Fibers

I'm in the process or updating my rust dyeing information - the part about neutralizing. Substitute out Baking Soda for the salt!!! I thought I had done this about six years ago, but apparently forgot to do so. So use 1-2 tablespoons of Baking Soda per gallon of water and upwards of a quarter cup of baking soda to 4 gallons of water.
