[GreenKeys] Re: rust remover and aluminum

[Paul A. Pennington]

    It surprises me that Muriatic acid can be used to remove rust.  I once 
used it to try to clean my garage floor.  The fumes from it rusted all the 
metal tools and brackets in the garage.  I guess the key step is washing it 
off.  Pretty scary stuff.
