<VV> Muriatic Acid Vs. Phosphoric Acid

[ScottyGrover at aol.com]

Phosphoric acid can be found in most hardware stores; it does an excellent  
job of cleaning iron and steel products, works slowly enough for you to  
maintain control of the operation  and leaves a protective coating (think  of 
the bluing on a rifle barrel.)  Muriatic (hydrochloric) acid is a bit  
strong-- would definitely clean your parts but requires much more careful  
handling.

I have  read about both of these acids in the Corvair tech guide, does 
anyone have any  experience with either one of these. 

I want to clean up some  half-shafts and suspension parts. Is Phosphoric 
acid easily found , if so  where? Which one seems to work better? 

What's the mix ratio  of water to acid on the Muriatic acid. Once dipped in 
the Muriatic acid, what  additoinal prep is needed other than washing them 
off prior to painting.  

Thanks.
