Re: Fire extinguishers

["Michael DeLuca" <mdeluca@xxxx>]

Many years ago in a time before Deloreans where built, I use to 
recharge dry chemical fire extinguishers.
The dry chemical that was used and I believe is still used, is 
basically Baking soda or Sodium Bicarbonate, they add something to
it to help keep it from absorbing moister and clumping. The propellant
is dry nitrogen (if you used compressed air from a standard air 
compressor it would have too much moisture and would clump the 
contents of the extinguisher). 
My point here is that other then making a mess I wouldn't think that 
the actual chemical from a fire extinguisher should not be particular 
detrimental to the interior of a car as far as from a chemical 
reaction standpoint. I'm almost surprised the Arm and Hammer people 
don't promote it as a way of keeping your burnt car smelling clean
and fresh after a fire LOL.
