[Chrysler300] Dropping acid not recommended

["Richard Barber" <c300@xxxxxxx>]

Acidizing chemical plant process piping to remove corrosion and deposits
with minimal attack of the good stuff is done with inhibited muriatic
(hydrochloric) acid--often with heat and almost always with circulation.  I
would not recommend it for motor vehicle (c3oo)ling systems as the
inhibitors prevent attack of metallic components and are carefully selected
and dosed for the job.  

Disposal of spent acid solution must also be done carefully to protect the
environment, eyes, skin, paint, garage floors, sewer piping and the
wastewater treatment plant.  If you decide to play boy chemist, rubber
gloves and goggles are recommended--as well as plastic (not galvanized)
buckets to catch the cleaning solution.

Oxalic acid crystals are available from cleaning chemical companies.
Formerly that was the primary component of Dupont #7 radiator cleaner----if
my memory serves me correctly.  Similarly you must follow the cleaning
routine with a neutralizer, usually baking soda.  I don't think that is as
harsh as muriatic acid.

Matt; I used Murattic acid (a gallon of pool cleaner will do). Run it 
through the system for a bit - re-flush it out and with baking soda to 
neutralize any residue acid. Another product I use to use was Ironcad 
(or was it Irontite- I think that is thecorrect name). May be hard to 
find and is expensive but was the best radiator cleaner (it's is a two 
part cleaner).
